Hi
Now before you laugh, yes I still have in my house the original Potterton Heating system from the 70's. As it has tanks in the loft, I assume its a gravity system. The problem is that radiators upstairs are perfect, but for the last week, the downstairs are cold. After reading these forums, Im sure it must be the pump as it doesn't make the kind of noise it used to!
I've attached several photos for you experts to study, including the diagram which is stuck on the Potterton door, I've marked in red where the pump is.
The pump is a SMC Comet 2-120F, what I'd like advise on is.. Are there direct replacements for this old pump, and if so, am I right in assuming that I need to drain the whole system, and undo the 4 bolts I've pointed out in the photos.
PLease any advise on if Im correct with the diagnosis of pump failure, and how to replace pumps.
Or am I totally off beat?
Thanks
