Which valve do I need for this

[BobbyJoe]

Which kind of valves do I need to prevent backflow issues with the plumbing in my home? Thanks

Where in your home is it happening, you have to paint the picture for us to help you.

This is like pulling teeth What is happening now that didn`t before.

The water supply in my home is contaminated due to backflow issues so I am trying to find out how to prevent this and was told that two types of valves need to installed in the bathroom pipework so I am trying to do a bit of research on this.

Clean water supply comes in and waste water goes out.
1 Are you in the UK?
2 Where does your water supply come from?
3 Where does your waste water go to?

right i think i know where you coming from

anything that mixes hot and cold

showers, mono style taps etc

to stop this you need to install a single or double check valve just before the valve/tap

Glad you are Shaun, thinking my crystal ball needs a service.

Bobby Joe, is this a new problem? Would rather cure the cause rather than the problem myself.

normally happens with lets say a shower with no check valves internally

mains cold and tank hot, the more powerful mains pressure will push back up into the hot cylinder and then back into the tank supplying the hot cylinder and cause it to overflow
