Hi
I’m in the process of redoing my bathroom and adding a exposed thermostatic shower mixer
I have a Potterton Titanium 33 (ErP) Combi Boiler
My question is do I need to add non return valves to the hot and cold feeds to the mixer ?
If necessary what is the maximum distance from the mixer that would be ok ?
Reason I ask is I have fitted everything already and intended to add them but forgot
I can add them about a metre away which is still exposed to fit
Cheers
