What Type Of Plumbing Fittings Should I Use?

Article by Peter Smith - Caravans Plus

We have three styles of plumbing fittings.

Push-on fittings

Push-on fittings

We mostly supply John Guest push-on fittings. Other compatible brands are DM-fit and WHALE.

Push-on fittings suit the semi rigid plastic pipe and are ideal for a new installation for Caravans and Motorhomes. Many of these fittings also screw on to threaded appliances and taps.

We stock a complete range of the most popular 12mm size fittings, and a limited selection of 15mm fittings. The size is measured on the Outside of the pipe (OD) and is a true metric size.

It can be used with Hot or Cold water, under pressure.

Full details on using these fittings

Hose and Clamps

Hose and Clamps

The last more basic form, is hose that clamps onto fittings. Generally used where manual pumps and cold water only is used. Larger diameter hose is also used to fill water tanks, connect between water tanks, as well as drain from sinks and showers.


Connections between the above plumbing systems

It is possible to join from one plumbing system to another using fittings. We have designed the online shop to allow any plumbing appliance or plumbing fitting to show what connects to it.

Look for the 'Product Connections' link below each products description.

    Hi. I'm no expert but I had almost the same problem with my slide on camper. In my camper, the town water filler assembly contains a spring-loaded non-return valve to allow water to go into the camper, but prevent water flowing back out through the assembly when the 12V pump is being used inside. It sounds to me that your non-return valve is leaking. In my case, I solved my problem by installing a new non-return valve in the piping just inside the wall where the town filler pipe enters. Alternatively, if it's not too expensive, you could replace the whole town water filler assembly that contains the non-return valve. There are several videos on YouTube that discuss this problem. In some cases, the problem has been caused by a rubber O-ring in the non-return valve becoming loose and the problem was fixed simply by pushing the O-ring back into place. Good Luck with your solution.
