I had to drain the cold water tank to fit a new thermoelement in my Grohe shower.
When i refilled the cold tank i discovered I have an air block in the hot water system.
I think this is most likely because I ran the shower before the cold tank was full.
I have tried many methods to clear the air block. Hose between hot and cold taps, reverse hose washing machine method and holding palm of hand over shower room basin mixer tap to force cold water into the hot pipe.
I have a Stuart Turner 3 bar monsoon pump. After using the above methods I can get water to flow out from the hot taps briefly and the pump runs, then in slows to a trickle and stops. The pump stops.
I took off the hot in hose to the pump and cold water is gently pushing up on the hot side (as though it has crossed over in the pump).
The kitchen tap which is not pumped won't flow. The basement hot tap which is pumped will flow for a while, but only cold (even though the hot water storage tank is hot).
I'd really appreciate any advice - The hot storage tank is hot, but I can't get any flow from it. The pipe leaving the top of the tank has a valve, this is fully open, but no flow. I suspect there is air in the cylinder.
Thanks
