Thanks Madrab. Just to clarify; the head was turned through 180 degrees from original so the pump is pumping down. In fact the arrow on the brass body points downwards.

The pump flow is pointing down and the F&E tank level rises about 3/4" as it heats up. So that's why I don't think it's water overflow and must surely be condensation collection in the overflow outlet pipe ?

Thanks fixitflav. I'm interested you think 36 degrees is not to bad. I just thought it seemed a bit hot. The pipe that is dripping is the one which leaves the top of the f&e tank and goes to the outside of the roof through the facia board. Not pouring but short periods of dripping during...

This is the pipework set-up before the pump was moved.

Just to add :- the boiler is set at 65 degrees there is no water entering the tank via hockeystick vent pipe when heater is on

Thank you all for your comments so far. Much appreciated. This is the current "H" layout on my airing cupboard. A bit more background..... I recently had a new Vaillant ecoplus boiler fitted. I cleaned out the system properly had all the radiators (18) off and cleaned them thoroughly. Replaced...

I am not getting over-pumping and it is definitely hot water migrating slowly up the feed pipe Thanks for your U Bend suggestion though, I think that might help a lot. I haven't had a chance to do this yet but will try.

I have an "S" plan open vent system newly flushed and new boiler, pump, etc etc replaced. Normal pipe arrangement, one zone for central heating and one for the hot water. All radiators and water HW tank heating fine BUT..... Hot water is migrating up the F and E tank feed pipe. By this I mean...
