Loss of water pressure after installing new shower and bath

[triggaa]

Hello All,

I have just installed a new bath and new shower and in the process I seem to have lost my water pressure.
Used to be great now its no better than a dribble.

I have extended pipes but not by much.

Downstairs the pressure remains fine, its just upstairs.

I'm wondering if I have some how damaged the header tank stopcock whilst turning it off and on or whether there is debris in the pipes some how.

I'm a DIY'er and new at it and am a bit stuck.

Any help would be appreciated.

Thanks

Matthew

are there any isolators that arent open fully

Have you checked the basin? If the flow on the basin is reduced I'd be looking at the stopcock or gate valve.

If you've closed gate valves there's a good chance they are jammed shut.

Check for filters at the end of the nozzle , take of shower head to check flow

have you used flexis anywhere, is there a kink?

Common fault

If the new taps have check valves in built. There could also be another problem

Thanks for all your replies. I think I have discovered the problem.
I check all of the tips I was given above, with a more experienced friend, and found no faults. Without either the shower unit or bath taps connected I had brilliant pressure. On further investigation this is what I think caused the problem......

1) The lack of water pressure in the shower
A) I bought Tool stations cheapest shower unit. It was faulty, only allowing the hot tap to run through, so only giving half the volume of water. I replaced the unit and it now works finr.
2) Lack of water pressure in the bath.
A) I used 22mm copper pipe to run the water up to the taps as all the books say so. But the flexi pipe that adds the copper pipe t the taps has a tiny bore, less than 15mm. This is the only reason I can find for the lack of pressure. bad design!
