Good morning,
I have a query about single check valves/double check valves/non return valves and their purpose.
I moved into a flat built in the 1960s and I think the bathroom was last upgraded around 2007 perhaps even before.
I am going to get it completely redone next week (new suite/ taps etc) and want to have single check valves installed in the bathtub water pipes and the basin pipes because the pipes don't even have isolation valves or anything.
Could someone advise if check valves of any kind are mandatory to have installed and if so their purpose and how many are necessary. My main concern is ensuring their are no back flow water issues, fresh water is always flowing in the correct direction and would appreciate advice from experts so that I can then inform the workmen what extras I need for the bathroom revamp, thank you.
