I am going to swap a CH circulation pump. When I put the old one on I used brass gate valves, and it is on 28mm pipe. I have an idea I might have cracked or crushed a washer when I fitted it.
the replacement Grundfos pump has been kicking around in the garage for a while, and there is only one washer in the box, I have been looking online for 28 pump washers but not found any, am I looking for the right thing? Any suggs where I can get a pair?
TIA
edited: I have just measured the washer and it is 45mm o.d. grey hard fibre
