I have a grundos niagara 1.5 bar twin centrifugal positive head pump in my airing cupboard with a cold feed from tank in loft and hot from the cylinder next to the pump. I think it is coming from the side of the tank with warrix flange. I first used the thermostatic mixer shower this weekend and it has been successful for 3 showers. However this morning i used it and the pump did not kick in and no water came out of the shower. I tried turning the temp on the shower to the min and it worked fine (though very cold) turning the hot back up gradually made it warmer but the pressure disapeared and became splutery.
I think I may have an air lock on the hot side.
Is there an easy way I can try to remove this? My pump instructions say use an essex / surrey flange - has the plumber used the wrong kind?
