Tap pressure

[davetherave]

Hi all Fitted new bathroom mixer tap with shower attachment only to find I've lost most of my cold water pressure. I have a combi boiler running hot water and central heating and downstairs water seems to run off mains. Cold water upstairs runs off loft header tank. The tap instructions indicated a low pressure min drop of 1.8m from tank to tap. It would appear that I just have this height. Any suggestions for keeping these taps and improving pressure would be welcome. Thanks Dave.

Thanks Dan. I'm not a plumber but like to do most things myself. I find these forums helpful as opposed to most stores where people are only interested in trying to sell you something! Cheers Dave.

can you reroute your cold feed to come from the mains?

Best way would be as Tom says,not matter what ,you are not going to get a good shower with the set up you have now 🙁

imho

Dave, you need to disconect and remove the tank. Connect the mains water feed pipe which supplied the ballcock onto the outled pipe from the tank, this will give you a balanced suply to your bathroom taps which will solve your problem.

Hi Brian Thanks for post. I live in a housing trust property but the landlord will only repair / replace existing old units. Do you think I can make the connection you suggest simply and still leave the tank in situ. Cheers Dave.

no reason why you would have to remove the tank but you will need to drain it as the water will go staingant so you may as well remove it at the same time

Ferret is right and if you want just leave the tank in place and pipe around it
