First off, apols for my absence from here for last six months: my arthritic fingers not been up to using keyboard.
Anyhow, my Qu.
Having a nackered bath tap, have decided to replace with a batth filler/shower mixer.
Should I place a double check valve in the cold water feed to this?
I would have thought such devices would have incorporated some such function, but nowt int description informs me that they do!
My cold water pressure normally delivers around 13 litres per min, but on rare occasions will disappear completely. (Not being caused by any other water draws within the property) When this happens, should the mixer be in use, I am concerned that hot supply from a header tank will feed through the mixer to the cold supply.
Thanks in advance, and regards to all on WW.
Have looked in from time to time, and my thoughts are with you, even though I have not been joining in.
