Fully serviced pitches are becoming increasingly popular. With the facilities in caravans including showers that can actually be used as showers rather than just to hang wet clothes the only downside was the water supply and disposal.
The supply side is catered for quite easily and there are a number of commercially available kits on the market to adapt your caravan’s internal water system to either a direct feed via a pressure regulator or a controlled feed to top up your Aquarol. It’s easy to understand why commercial kits are available, all they have to do is connect from a tap to your caravan’s water system via a length – or multiple lengths of hose and 99% of the time this can be achieved.
However, a system for the drainage is a little different. The problem is water has an annoying habit of only wanting to flow down hill. Before deciding on how I was going to tackle the drainage for our caravan when on sites, I looked what other people were doing. Nearly all were using a length of the standard grey ribbed flexible hose to connect the Y piece to the drain. This seemed OK if the hose length was one or two metres, but after watching one fellow caravanner keep wrestling with what seemed like a 300 foot length of springy pipe which most of it was just coiled round and round on the ground and every time they did the washing up he had to come out and lift sections of it to drain…. that was the way I didn’t want to go. I would have thought cleaning it afterwards would be a bit of a chore as well.
I wanted to go with a rigid pipe and still have the ability to adjust the length without resorting to short lengths of pipe and adaptors. On a trip to the local Screwfix Direct store I checked out the plumbing section. I wanted to use cheap standard pipe and parts where possible. The choice of sink drainage pipe seemed the way to go. There are three colours generally available, Grey Black and White. The Grey and Black have UV stabilisers so that years of being clipped to the outside of houses doesn’t degrade them. The white however is designed only for interior use, but it did offer an advantage. White is easier to see on dimly lit caravan sites and for the amount of time it would be outside I don’t think the UV element will be a factor.
There are two diameters of pipe available and one slides neatly inside another. So using the smaller diameter ‘upstream’ I could effectively have a variable length of pipe. A few elbows and angles should allow me to easily adapt for most conditions.
They say a picture is worth a thousand words….
I used the flexible pipes of the ‘Y’ adaptor that came with the caravan to connect up a manifold to join both caravan drain outlets. There is enough flexibility in these pipes to enable the outlet run to be skewed away from the van. I cut the two 3 metre lengths of pipe down so they could easily fit in the gas locker.
This is the set up used at Troutbeck Head CC site….
As the drain for the pitch was directly at the rear of the caravan, I used a length of flexible to add on a 45 degree bend so the pipe would run rearwards…..
I joined on a short length of pipe to my main “trombone’ sliding section with an adaptor and for good measure, I used a spare block of wood to support he extended length….
At the drain end, I use a 90 degree bend to point the flow down into the drain….. with a handy brick to keep it in place!
The original collection of fittings and lengths of pipe came to less than £12, and so far this system has allowed us to use all the serviced pitches we have been on, with one exception… Lady Heyes… for some reason the two pitches we have been on there, the EHU post and drain have been on the awning side of the van. Ho Hum…. you can’t win them all.
In use we haven’t had any problems and both the main sink, bathroom sink and shower drain easily. When we are breaking camp, the pipes are easily cleaned with running water and being white, its easy look down them to check they are clean. All the fittings are kept in a bag in the gas locker along with the two 2 metre and two 1 metre lengths of pipe. As the two sizes slide inside each other there is only really two lengths to deal with.
I hope it gives you some ideas on how you can connect up to a fully serviced pitch. If you have any ideas that would improve my system… let me know, anything to make things easier!
I already had a 2 into 1 adaptor supplied with the caravan that used the normal ribbed flexible pipe, so I used two of the three lengths of flexible pipe off this to make the connections between van and my system. I can always revert to the adaptor in the future if required. By using the flexible pipe as a connection to my ‘manifold’ it allows me to use it with the wastehog if required and I can just bend the manifold upward to remove the wastehog for emptying without having to disconnect anything.
The biggest advantage of using standard plumbing items is I can always go to a DIY store and add to the system if we find a pitch that I can’t connect too. I’m just looking now for something similar to a small awning pole bag that can take pipes at 2 metres length… or even the possibility of storing longer lengths along one of the caravan chassis rails.
Total price for this setup was £11.60. You can find everything here at Screwfix Direct

Instead of relying on a brick or a sandbag to hold down the end of the drainage tube, I use a 2 litre PET drinks bottle. It weighs nothing when empty.
Just a thought for storing pipes a rotary line or parasol cover is the ideal size and much cheaper than pole bags from camping shop.
Nice One!
Great check list of materials. Just popped into local DIY store and very easy to use. Looking forward to using your system at next couple of serviced pitches we use. Thanks.
Thanks Simon. This is brilliant and the pictures show what a flexible solution this is. I’ve just cross-referenced it on a Caravan Club discussion, which is how I originally found you. I’m looking forward to reading your other chronicles now.
Glad I came across this article to prevent the wrestling with 10m of flexipipe and poor drainage! Parts from Screwfix still cheap now. Aleady had the “F” shaped piece to go into the wastemaster, so two lengths of pipe, two straight connectors, two angled connectors and the 90 degree end piece for about £11.50!
Excellent article, thank you Simon.
Wow, brilliant. It always appears to be my job to sort out the grey drainage as Mr H generally disappears with a beer by this point in the setting-up process. I too have dealt with python-like grey pipe (to the point we went and bought some white, straight pipe last summer to run the grey pipe through to keep it straight and going in the correct direction) but this looks much easier. I’ve also stood in 2cm of puddle int he shower, hoping and praying it won’t gush over the top of the shower tray. Screwfix here I come!!! Thank you.
Great idea. I bought all the bits, convinced that it wasn’t going to be as easy as you made it look – but it was, and better than wrestling with the grey hose python. The worst bit was wondering how to fit a 3m pipe into the car to get it home, but the Passat swallowed it no bother. I think I’ll make up some sort of sandbag to weigh down the pipe at the drain end instead of relying on the site to have a few rocks lying around.
Hi Robert
I like the sandbag idea!!!!
Thank you for this great idea I have made up sets for different situations now and stashed them in a bags4all specially made bag. Got lots of interest on our stays both in the U.K. and especially France. Given the details to a Dutch friend of ours.

How do you connect the grey flexi pipe to the white pipe, is it just pushed fitted?
HI
The grey flexible pipe is a push fit in one of the standard pipe connectors.
Was looking for caravan drainage ideas and found this. You are a genius! There aren’t too many places in NZ that you can use this system but we’re now sorted for when we can. I did feel like crying however – the cost of 4m of pipe and 3 jointers came to a bit over $100NZ.. about 55 pounds.
Hi Simon, saw this sometime ago and thankfully now found it again. Tried the flexi hose but this is ideal and it will be on my New Years resolution list!
Finding your blog very useful and entertaining.
Thanks for taking the time to pass on your thoughts and ideas.
Allan
That is brilliant thanks will pop into Screw Fix with your spec ASAP

Great article. Thank you. Just bought a Sterling Elite 650 and couldn’t work out the best way of sorting this problem as I love using our own shower
Thanks for this article. I was browsing the internet recently looking for ideas to resolve this ongoing problem. I had been using this type of pipe but hadn’t even though about putting the smaller one side the larger one. I have been out and bought myself a kit as per your list. I even sat and made a small case for it all to go in from a torn awning bag. The new caravan is now completely ready for this season. If I could just find a solution to having the tv aerial trapped in the window and had the courage to fit some speakers into the shower room all would be perfect.

Have a great season!
Plastic-Express were prompt sorting out the order and the items arrived well packaged via Tuffnell Couriers within 48 hours. Followed the advice above and now have a great waste pipe set up for serviced pitches!
Thanks for this, when I contacted Screwfix most of these items (eg pushfit pipe 32mm x 3m) are sold in tens and not individually
Hi Dave
I think that might be a recent thing. I do know they are all available from B & Q as I checked a few weeks ago. I also think that it might be cheaper now than it was when I made my original set up.
Just ordered all the bits from plastics-express online. Thanks Simon
Let me know how you get on with plastic-express, I’ll include a link if they are OK.
Thank you Simon. Best article I have read on a caravan focused site. What you describe has happened to us with our new Pursuit in France. Took 8 days and set up that would make Wallace and Bob the bodgitt happy. Finally got them all to drain away but drew up plans to do something similar to your idea. When we get back it will be the first job.
Hi Simon, I have used your listed set up, plus a few more elbow and other odds and ends at all the serviced pitches In have been on. I have even had to cope with the caravan being parked the wrong way for drainage because I did not have a fresh water hose extension for the aquaroll. getting the flow right was a problem, but I got it sorted with corner steady blocks etc.
At the end of the stay just use what hot and cold water you have left to flush through and you have clean pipes. I cut all the tubing so that it would fit in the front locker of my Lunar Clubman along with my “Bag of Bits” Brilliant.
We seem to be staying at the same sites, Old Oak, Plough Lane, one day we may meet up as we use both sites on our trips south. We are off to Two Mills Touring Park Norfolk for a week this weekend, then back to Plough Lane at the end of October for the Autumn colour show at Westonbirt Arboretum and Dyrham Park.
Great blog Simon, enjoying the gear reviews also.
tell you what, Simon this is the most useful blog I’ve seen and you’re right that pictures speak volumes. I’m hopeless at DIY but even I fancy myself to get this right. I’ve just bought a 2015 model but I don’t know what the size if the drain holes are in diameter. I’ve just bought the ‘Drain Away’ from Care-avan (I now realise it’s a rip for what it is) but I don’t know whether the diameter of the flexible hose is big enough. Would you know the answer? Great info on it all.
Excellent article.
I’ve followed your parts list, and added a 40/32mm connector in order to form a seal between the 2 pipes if need to go beyond 3 metres.
As I was messing about with the corrugated hose supplied with the caravan I realised the OD/ID of the corrugated hose is the same as the plastic pipe so formed a manifold that plugs directly into the caravan drains. I think this will reduce the build up of muck in the corrugations.
I have a Kador / Safari strip from a previous life, so will use short lengths in the skirt track to make supports for the drain pipe if it runs alongside the caravan to maintain a suitable drop along the length. Similar to your Fiamma part.
I’ve fitted the 32 inside the 40 with a cap on the end and fixed using cycle carrier straps to the caravan chassis underneath to keep out of the way for travelling.
just been to screwfix last night to make this , amazing idea, i got a flexble piece of pipong so no need for extra joints etc to carr it connects from the t piece dierc to 32 mm pipe
Great article. I have become frustrated at having to lift the flexible waste pipe to fully drain for some time and we have suffered from back up into the shower tray. This will also be great for serviced pitches in Holland this summer.
I have just purchased the relevant bits from Screwfix for the sum of £12.60 and will use them at the Edinburgh or Strathclyde Caravan Club sites this weekend. There are sellers who charge £10 just for the t section near the caravan waste outlet.
Great idea !!! far cheaper than the readily available stuff !!! Just one small question (or is it me being a bit dim ?) on the shopping list, the last item is 2 x 90deg conversion bend …is that 2 x 32 or 40 or 1 of each ??? Sorry typical northerner !!!!
Hi Peter
The conversion bends are 32 to 32 – Its a 32mm female to 32mm male, most bends are female to female. One is used to make up the first part of the manifold so it allows the flexible pipe to push into it but the bend pushes into the ‘T’ piece. you can see it better in the close up, second photo down in the ‘update 1/7/2013’ bit of the article. I used the second bend so send the pipe off sideways as seen in the photo “The Old Oaks, Pitch No 2, Walnut circle”
Hope that helps
Simon
P.S…. now’t wrong with northerners… I’m one meself.
Cheers Simon,
Will be off to thou local Plumber’s tomorrow to purchase said items…. plus a bugee and noticed the wooden leg thingies !!! off to obtain some wood about inch thick and eight inch square…. being a Northerner and damn proud of… shall look in ones shed first, also some string to fancy them up a bit, make them look expensive !!! thanks again !!! Got told today we talk funny …… I said we look funny too but who cares !!!! According to the girls in Milton Keynes we all wear flat caps.. I said its true !!! see ya soon. Will send pictures of first outing soon….well if I get back !!!
I have only just come across this blog. I have used super pitches for a few years now using just the corrugated pipe. This looks so simple to do even an idiot like me will find it simple. I will just have to wait until I get back from Spain in February to get the parts sorted. Then see if I can use them before going to France in May.
Thank you very much.
Super Article. My first super pitch booked for Easter 2015. Got the shopping list and now all the ideas I need to implement – great
You mentioned advantage of a site with two taps for filling a water jug or kettle.
Every site can in effect become a two tap site if you use a splitter that screws onto the tap. One side for the van connection, one for the jug or kettle (or hosepipe to,wash the van or car). They have a small lever on each outlet to turn supply on/off.
Hi Simon
I’ve been considering getting super pitch gear for some time so what a find Caravan Chronicles is, and this blog in particular. Thank you for going to the trouble to list all parts required, and detailing some of the set ups you have used at various sites, so next stop is Screwfix or B&Q. I have just ordered the Aquarol kit so we will be all set for our visit next week to Old Oak.
I have also been reading other items on this blog. Great content.
Once again thanks for the tips.
Hi
So glad you find the blog useful. Hope you enjoy your trip to The Old Oaks… probably our favourite site. Say “Hi’ to Tara for us.
We’re off to ‘sunny’ Blackpool next week to do out annual ‘cycle the illuminations’ trip… just hope the weather cooperates!
Cheers
Simon & Sue

I have just found your site. What a fantastic site with some very interesting ideas. The waste water one is brilliant. Thank you
Brilliant write up and a brilliant idea. Thanks.

Two iossues with the otherwise helpful article
1. This works fine when the drain is close. However on many continental sites it may be 30-40 ft away central between 4 pitches. So the fixed runs will not do.
So it will be back to flexible grey water hoses.
I don’t use the ‘ribbed’ version as (like you say) it is difficult tyo clean. I use 1 inch flexible hose.
2. Again when long drain runs are required. As you say, there is a reluctance for the grey water to flow to the drain. Using a Y connector to join both Sink and Shower drains together next to the van provides the sink gray water with an alternative place to go – Back up the shower drain leg and into the shower tray – Not the best place for washing up water. The sinks are 4 ft above the connector whilst the shower drain is only 1 foot.
The ultimate solution is to ensure that the shower drain is seperated from the sink drain – both kitchen and bathroom. Then run each grey water run seperately to the eventual site drain. Normally I have found that a 10 ft dual length from the van then a Y connector works fine.
Hi Roger
Thanks for the comments.
My solution covers a lot of situations and was relatively cheap and easy to do, as I said in the posting, there are exceptions…. Lady Hayes was one for us.
I have never had a problem with sink water back-flowing into the shower tray. The outlet from the manifold would have to be 50% to 75% occluded I suspect for this to happen and as the flow rate from the sink is relatively limited I think the risk from the current pipe setup is low.
However, as you say some locations require the use of a flexible pipe to cover a distance of 20 feet or more will sufficiently reduce the flow, especially as it is unlikely that it will be on an even fall to the drain and could cause a backup into the shower tray. I think if the drain was that distance from the van, I’d revert to using our wastehog in preference to cleaning out 10 or 20 feet of flexible hose.
To stop any chance of a back flow and to stop any chance of smells from the waste pipework entering the van, I installed Hepvo waterless valves. http://www.hepvo.com/ and they are available in the UK (manufactured by a UK company).

Hi Simon
Excellent work so far sir.
Heartily congratulate you for your work in educating the caravanning world.
For my sins I’m a civil engineer by trade, and although im not a hydraulic engineer specifically, we are required to have a rough understanding of hydraulics for drainage purposes.
One of the reasons that the normal ribbed grey pipe is not ideal for use in longer lengths is due to its internal ribbing.
All pipes have a property known as their Pipe Roughness Coefficient. There are a number of different measurement scales but the principal holds that the coefficient varies according to how rough or smooth the internal surface of the pipe is. Steel or glass lined (chemical) pipes are very smooth and concrete is rough (obviously). This is on a microscopic scale by the way.
Smooth pipes allow the fluid to pass more efficiently whilst rougher pipes impede the flow.
The flexible (and ribbed) pipes automatically slow the flow down to a large extent (even with a 1m head) and then, when combined with a few undulations in the pipe position suddenly there is no flow.
Your 40 / 32mm pipes are smooth on the inside and will therefore be a far better solution that the ribbed pipe.
Don’t get me wrong, if there is a reasonable gradient the ribbed will work, just not as well.
As I said I’m no expert but this will certainly have an effect.
Keep up the good work
Regards
Rik White
Have to say Simon, I love readin caravan blog posts but this is up there owith one of the most useful ones ive seen around. Actually useful and will help a lot of people out.
Hi Sam
Thanks for the kind words.
I guess a lot of others must think so too, I have had nearly as many visitors so far this year as I did in the whole of last year – only about 400 more to go.
S
Clever as always… nice one!
Thanks Chris 🙂
I can’t understand why some of the magazines never do articles covering practical items like this? Caravanning had it’s roots in active DIY’ers and that seems to be lost now.
