Hi, can anyone advise me on the correct direction of flow? I removed the pump to clean it, but didn't note the direction. Should the flow be towards the motorised valve or away?
central heating pump Urgent Help!!!!
- Thread starter carctol
- Start date
I had a trainee who forgot to check a pump direction ( once! ).
In that case it was remote from the boiler and the motor valves.
He had to try it and see the flow at the boiler. His first guess was wrong! Now he takes my advice and checks first and draws an arrow on the adjoining pipe!

Whilst that is the correct way to design most systems nowadays, older systems used to have the pump on the return because it ran cooler there. You cannot guess!
Many commercial systems have the pump on the return too.
Most combi boilers also have the pump on the return. ( I would say all but someone will know about one that I had forgotten about with it on the flow! ).

No need for that, Gasman1015. Chris is absolutely right. It's unlikely but possible.
Carctol - all you need to remember is that the pump should drive the water from the highest point in the boiler to the lowest point, regardless of where it, or the valve, sits in the circuit.
Indeed he was. This is a subject close to my heart. Once, laid up wth flu, I had to call an engineer (CORGI) to replace a pump that broke down in mid-winter. He fitted it the wrong way round and rogered the boiler. "Oh, I thought it was one of those with the pump on the return" said he, writing out a bill for £180.
From that point on, I vowed to do all this stuff myself.
