My shower and bath taps are both fed by a Hansgrohe 2 bar pump. The Hot Water is fed from the tank and the cold feed comes directly from the Cold water tank in the loft (I think, not sure it its mains or not).
When the shower is running the pressure seems to slowly drop off quite badly. I've found that if I turn the shower off and then turn on the HW from the Bath tap (which is also fed from the same pump) it seems to sort the problem out. When I turn the bath tap on there is sometimes a cough and a splutter then it blasts out. BUT, if you leave it for a few seconds the pressure will slowly die down, then a few seconds more and it picks up again, and continues this cycle. If I then turn the tap off and turn the shower back on the pressure is back at the shower?
There is a small air vent type pod with a small black cap that tightens and unscrews on the pipe that exits the top of the cylinder through the surrey/essex flange. The cap is loose to allow air to escape.
The pump doesn't sound too quiet when its running either, but it was fitted when I moved in and therefore I've assumed its a normal level of sound it makes. Although a retired plumber friend said it was too loud when he heard it running, and suggested that I strip and rebuild it if possible.
Any ideas chaps?
