Hello
I have a sealed ch system that I am trying to fit a new 3 way valve (leaking) and a water pump (nocking) in one go, problem is that the two shut off valves at the pump are solid screw type and will not turn even with a large bladed screwdriver so I am stuck.
Looks like my only option will be to partially drain the system but I only want to drain it low enough to swap the pump & 3 way valve leaving the rads full, hope this makes sense
I have two drain valves that I am guessing are for emptying the system but I am not sure which one will do the job these 2 valves are located at the lowest point at the hot water cylinder one is permanently cold and the other gets hot when the boiler is heating the water.
Is my plan to lower the water above pump / 3 way valve workable, any help would be appreciated. Thanks.
