I posted a question last week regarding the water pressure/flow in our shower. The hot water pressure is pretty bad whereas the cold is superb.
The pump supplies both the shower and the bath taps, and I've noticed that when the hot water pressure/flow starts to drop in the shower, if I tuen the shower off and run the hot water tap in the bath it'll cough and splutter some air out, then it'll run but the pressure will build up and then slow down again.
Then when I turn the shower back on the pressure is pretty good for about 30 seconds before it drops again. All the way through this the cold water pressure/flow to the shower and taps is spot on.
I've been up in the loft and checked the cold water tank when the shower is running as I thought maybe it was emptying faster than it could fill but this isn't the problem - than tank is massive and fills adequetely. I just wanted to check the pipework looked correct before I attribute the problem to the pump.
This is how its set out:
The little air valve on top of the hot pipe that comes out of the pump is open too so I dont think thats the problem. Got a feeling a new pump is going to cost a fortune - its a hansgrohe/Axor/Pharo one yet I cant seem to find them anywhere.
Any help much appreciated, thanks
