The John Guest 12mm Check Valve is the perfect fitting to stop the flow of water from reversing and returning the way it is fed from in your hot or cold John Guest plumbing tubing. It features a one way non return valve that shuts itself when the back flow of water is detected. This compact check valve will fit in confined spaces in your Caravan, RV or Motorhome and can be used for many other applications to stop back feeding of water. Certain fixtures such as water filters may require you to install one of these 12mm non return valves when plumbing them up to ensure water flowing in the one direction. There is a direction of flow arrow located on the body of the fitting for clear installation. The maximum working pressure is 1000 Kpa and maximum its temperature rating is 65 Degrees Celsius intermittently. Its ease of installation uses the same John Guest push fit technology where stainless steel teeth grip the tube once pushed home. Locking collet clips are optional but encouraged to stop accidental disconnection of the tube and fittings.

This is an industry-standard plumbing connection system for 1/2" (12mm) "Speedfit" pipe to be connected to "Speedfit" Twist & Lock fittings. The system allows you to connect pressure hot (80°C) and cold water plumbing throughout your RV, caravan or boat on your own, without help with almost zero likelihood of hose bursts. The hose comes in 2 colours, there are a huge number of standard (BSP, etc) type fittings to enable you to connect to sink faucets, hot water systems, toilet cisterns, indeed any potable plumbing at all. If you need to connect up almost any plumbing application, this is the one for you. Shown below are the various fittings that connect to the Speedpex plastic pipe via Twist & Lock fittings. To do the job, you will need fittings, pipe, pipe inserts clips and spacers, and a pipecutter. (You may not need all of this.) Most of the time, the hose simply pushes into the fitting. There are some fittings which are 'barb' type or 'stem' type. These connections are generally secured with a hose clamp. You will see 'stem' or 'barb' in the description to denote this. The tubing (Red or Blue) is made from Linear Low Density Polyethylene (LLDPE) and is foodgrade. You can even run compressed air, CO2 or nitrogen through it. It will take up to 150 PSI (10 Bar) at 20°C. Trust us, unless you are a plumber, this is the best and most efficient way to tackle that otherwise daunting plumbing job!
