Hello
I have a shower fed from the cold tank and hot cylinder, no pump (water-saving!). please excuse any terminology errors here..
Plumber replaced part of the feed to the cold tank last week and his new pipe rises a little higher - about an inch - before entering the tank. The RHS of the ballcock is therefore a little higher but this tilts the ballcock lever so the water level in the tank is about 3 inches lower than it was before.
Can this affect the water pressure for the shower and bath - they seem worse? 3 inches isn't lots but the pressure aint great as it is (tank is three floors up, one floor above the shower). I did have to clear a lot of crud out of the tap filters to get them running at all after the work. At first some taps let almost no water out but improved a lot when I removed the lumps of rust and copper salts blocking the filters (the system has been out of use and drained down for a year - this is not the plumber's fault!).
He says bend the ballcock lever, which I didn't want to do as three inches is a lot and the rubber flange may not marry that well after that. I did consider doing this myself but felt I would then be annoyed if I broke the thing fixing his error.
Is there any other reason to worry that the cold tank now has a lower volume?
I would appreciate some wisdom on this. My recollection of basic physics suggests the head of water should affect the pressure although maybe not by much...
I usually do all plumbing myself but we found some leaking lead pipe (!) when a gas safety check was being done and I'm living 100 miles away so it seemed best just to have someone else do it. I would never have left the inlet at such a different height but I'd like to know if it matters at all.
thanks in advance!
