Plumbing Valves
Plumbing valves help isolate individual fittings, shut off water supplies and make maintenance easier. Choose from 15mm and 22mm isolation valves, service valves, stop valves and basin shut-off valves, including straight, angled and concealed designs for different installations.
Single and double check valves help prevent reverse flow, while thermostatic mixing valves blend hot and cold water to deliver a more controlled outlet temperature. Our selection includes 15mm, 22mm and 28mm TMVs, with TMV2 and TMV3-approved options available for suitable domestic, commercial and accessible bathroom projects.
Air admittance valves allow air into the soil system to help balance pressure and protect trap seals without letting foul air escape. Choose from 110mm push-fit and solvent-weld models, along with combined pan connector and air admittance valve designs where space or access is limited.

Double check valve
25th February 2026So, according to the regulations, a double check valve, is needed to be fitted to our shower hose for our bidet. Having wasted money on 2 previous JG push fit, double check valves, only to find they were both really loud because they were attached to the mains water pipe. So, every time we flushed the loo, had the washing machine on, filled the sink etc there was a loud whiring noise due to the mechanism. We had to pay to have them removed. We then purchased this very discreet double check valve, that doesn't sit direct on the 15 mm pipes, so is perfect as a retro fit, to meet regs. It screws on really easily, where the hose attaches to the mixer. It does whir a little but not as loud as the JG and only when we use the hose is in use. So, we have a much quieter home as a result and the double check valve matches the chrome mixer and hose too, so very pleased.
