Help: My bath cold water Tap is very slow
 

Hi everyone.

I wondered if anyone could help.

I turned off my water this morning to fit new taps down stairs.
Drained all cold and hot water.

Now everything is plumbed back in and I get hot and cold fine everywhere APART from the bath where my cold tap runs very slow, a trickle. Hot tap is fine.

The wash basin in the same bathroom has no problems on the cold tap.

I can’t work out why this tap isn’t working?

I know my hot water from the bath comes from cyclinder and there is a cold water tank in the loft so could these be related?
I’m guessing the other taps are directly on the mains?


Any help appreciated.

Thankyou.

Edit: Sorted it.
Just blocked both hot and cold and the pressure must have sent the air up back into the tank as it bubbles and now working.

Glad you got it sorted. Sounds like a simple air lock.

It's common practice to feed the cold water tap of the bath (only) from the same tank that provides the water to the hot water cylinder so both are under equal pressure. This is to ensure that shower mixers can regulate the temperature properly.

The wash basin cold tap is fed from the rising main so that potable water is available here. It's advisable NOT to drink from the cold bath tap. You never know what might have crawled into the loft tank and died. :D

I was going to suggest air locks - glad it sorted itself.

If you ever get an air lock in a pipe fed from a header tank and it won’t clear itself, you can clear it by attaching a hose to a tap that’s fed direct from the mains, then to the tap that’s dribbling, and using mains pressure to force the air back up to the header tank.
