could someone please explane the correct lcation of double check valves?
I have been plumbing up to my sink, in the kitchen. I have had a look at a few installations and they do vary, I understand that the valve is to protect contamination.
I have seen the valve fitted just after the stopcock in one persons house, and on another I have seen one just fitted where the main tee of to the boiler.
1,what is the correct location for a double check valve, and can you have more than 1 in line.
2, why a single check valve
thanks Darren
