Low cold water pressure problem


Hi peeps,
I am new to this forum but am a semi skilled DIYER, done my kitchen and bathroom all myself and on budget.

Anyway I am hoping for some advise, the bathroom is fitted with mixer taps, the problem is low cold water pressure from the tank in the loft, it was OK before when there was individual hot and cold.

The water runs off a combi boiler except the cold feed upstairs for the bathroom and toilet.

Can this be corrected without having to get a pump, am I missing an obvious solution?:confused:

Please help

Thanks.

Low cold water pressure problem


Do any other faucets have low p.s.i ? If not I would (you might think this sounds ludicrious) remove the line at the faucet and remove the shutoff valve (shut off the main 1st obviously) and look for little rocks or pebbles that accumulate by valves. I've had to use my compressor w/ blowgun attatchment to blow the damn things loose ...

I'm getting the feeling that you are gravity feed on the cold side?

Sounds like when you did the new plumbing that some scale inside the pipes may have been dislodged, and is partially clogging the cold side of the faucet.
Turn the water off, take the faucet apart, lay a towel over it, and turn the water on briefly to flush it out.
Good luck!
Mike

thanks allot for the suggestions, going to try some of these at the weekend, i think there is an obsticale too as I have had to empty the loft cold tank twice in as many weeks to if there was something in there it my be blocking the out let, the pipes in the bathrrom seemed to be running free and easy before I did the basin tap change.

Will it matter if the basin mixer is dual flow or not with the unequal pressures?

No. If you take the faucet apart, dual handle (cold side) or single handle, it should flush out. Mike
