A lot of new caravans now have the ability on a ‘super pitch’ to be able to attach a mains water feed directly to the caravan without having to have an Aquarol as a water reservoir, and this seems like a good idea. I started looking at the options available and was surprised at the cost of the only suitable system for our caravan. I also wasn’t keen on the plastic regulator. This got me thinking, maybe it was time for a little Caravan Chronicles DIY project.

I wanted to come up with some sort of contrivance that was assembled from stock components that were easily available anywhere. After a brief search on Amazon I came up with my shopping list and ordered everything (see links below).


The result was a simple to use commercial pressure regulator that I could use our existing blue water hose that originally connected to the Aquarol and standard hose fittings that allow me all the options for connecting up.

IMG_0526As a temporary mount I used a couple of the small plastic hangars that Fiamma sell that slide into awning rails allowing you to hang things from. In this case a couple of cable ties held it in position. I’m currently in the bat cave folding a small aluminium plate to mount the regulator on that slides into the rail and has a foam padded back to protect the caravan. I opted to use brass fittings for the hose connections rather than plastic just for durability.

So how did it work out?

Well on a recent trip to Southport Caravan Club site (where the photos were taken) it worked extremely well. The initial set up was easy and to start with I reduced the pressure using the small screw on top of the unit to about 0.5 bar (7 PSI) to ensure I didn’t over-pressure the caravan plumbing. I increased this to about 1.5 bar and this gave an excellent flow rate with the added feature of not having to run the internal water pump.

Something that was in the back of my mind however was what if the regulator failed and full mains pressure was allowed through to the caravan’s internal plumbing? As I’d used a commercial unit, hopefully the chances of this would be very slim to non-existent as these units are designed to be permanently installed in commercial and domestic plumbing installations however I also added another little handy gadget at the tap end…

IMG_0547This ‘Y’ fitting has two small ball valves, one of each outlet. So when we go out, I simply turn off the appropriate ball valve. Having a ‘Y’ adaptor also allowed us to fill up our Brita filter jug or draw water off without having to turn the tap off and disconnect the caravan hose. All in all everything worked out perfect. (note I have since changed the blue hose adaptors shown for brass ones for durability).

One last thing…

If you are at all worried about water quality in your caravan, connecting up this way will allow you to thoroughly flush out your caravans water system and give you clean water from your caravan’s taps, (especially In summer too, when the sun has been warming up the water in your Aquarol all day) all you need to do is just run the tap for a minute or so to get cold fresh mains water.
