Cynthia Asked :I have to replace my shower unit as it appears it does not have a non-return valve or if it does it has failed. The manual Sagittarius unit is very similar to the one I have. I need to know if it has a non-return valve in-built or if I have to buy one. I understand this is needed as it will affect the new boiler just installed.
Answered By QS Team :
Yes, this valve has non-return valves in elbows.
