Hi, thanks for reading post.
I’m working in a large house which has 3 upstairs bathrooms all with showers and baths. Hot water pressure is very poor so looking to add a booster pump to the hot side. Cold is taken from mains to all bathrooms.
Have added booster pump to system and turned off secondary system pump and valves so no hot water should be returning back to cylinder. But the pump is constantly on and pressure indicator on cylinder is showing large fluctuations. Struggling to trouble shoot why water still returning back to cylinder.
System is quite old so could secondary system valves be perished? There is one immediately before and after the brass pump?
Any advice greatly appreciated. I have a small building contract company, and customer wants us to increase hot pressure.
Many thanks.
