Stuttering Water Supply

[nevmac]

Hello,

I have a problem with the hot water flow within my house.
It is very obvious when using one of the power showers, where it stutters and really struggles to get the water needed. It seems as if there is water in the system.
I have drained the system, and put in a 'u' bend in the copper pipe that exits the top of the hot water tank.

Any advice or suggestions would be great.

Thanks,

Thank you for your response.
I am slightly lost on this? The pump was done 'professionally' so am assuming that is all ok.

The problem with this stuttering water is that it affects the other shower as well which draws water but does not use this pump.

I might be mistaken but AFAIK there shouldn't be any draw off from the horizontal vent pipe (the one out the top) until after it meets the vertical vent and that's has to be 450mm min long. I also thought a 'u' bend was only to go from a Essex?

Hi. The main supply to electric shower and the supply via pump are not related. have a word with neighbours as it could be work taking place on water company main and effect others in the area, until such time as any air is drawn off.

what is the pipe for that tees off the hot feed to the pump?

i believe that is the hot water pipe, and the plumber has teed off of it to feed the new pump for the new en-suite shower.

The tap in my en-suite now drops to a trickle when i turn it to hot. This also seems to be the case for the shower in the main bathroom. I have not tried our en-suite shower.

HELP...PLEASE
