Hi,
We had a Techflow 3 bar shower pump fitted a couple of months ago. The pump is fitted at floor level of the first floor about 8 metres from the hot water tank. It supplies an ensuite bathroom. The header tank is above the hot water tank in the loft.
When you try to switch the shower on (preset to hot) you get no water or pump for about 90 seconds. Once the pump does start the shower works fine.
The shower works from a Hans Grohe Ibox and has a rain head along with two pencil handsets, fitted at waist height. If I switch the diverter valve to the handsets I get water and pump on immediately.
In addition, the bath taps will switch on the pump immediately, however the basins suffer the same problem, cold water switches on the pump immediately but if you ask for hot, there is a long delay before the pump switches on and you get water.
There are two manual air valves on the hot and cold pipes going into the pump and I have checked these and there is no air.
So I just wonder if anyone has any ideas as to what is preventing the pump from switching on when the basins or shower ask for hot water?
Any help or ideas would be gratefully received.
Thanks for your help!!!
