Can anyone advise.
Just fitted a circulating pump to HW tank. Connects the vent pipe (approx 60 cm from tank top) to the drain connection.
When the pump starts up it is fine. However, it collects air and then stop pumping.
I have avoided puttting an essex value in as the top connection already has a power shower and the vent. the power shower is fine.
Should I
a) Get a lower speed pump (this is a CH pump on setting 1 - 35w)
b) Move the connection closer to the tank connection
c) Accept that an essex valve must be installed - route both the powershower and circulating off the inner connection. Vent of the top as standard.
Thanks
Geoff
