Water dipping from tap constantly.

Sir_luksik

Hi folks. I'm trying to replace the old mixer tap in the upstairs bathroom myslef as I thought it would be an easy job. However, despite turning off the main water supply and turning off the valves in the house the water is still dipping from the tap. Any ideas what might be causing this?

I've found that due to the age of some plumbing some taps can keep dripping even when you've turned off everything.

If it is just a drip you can sometimes lessen it by turning on other taps in the house. That might give you enough leeway to change the tap.

Unfortunately the issue is not with the tap itself. The water is still coming to the tap through small plastic pipes from the floor. When is unscrew the tap the water is just coming, it's at very low pressure but still. Will be a.lot of water by the time I change the tap.

If you have a length of pipe coming up to the tap then you can cut it and very quickly put in an insert then put on a push fit isolation valve

Only issue is checking if you have 1/2 inch or 15mm pipe. Irish fittings are imperial but there is still metric pipe around.
