NEED HELP WITH FACET

remove the end of the gooseneck (or whatever style you have) where the water is supposed to come from. There should be a screen in there that may be clogged with debris.

Clean it out and re-install

Did that and it still doesn't work. This is a gooseneck facet.Any other suggestions?

Is the pipework galvanised or copper in your house?

If it is galv & probably old it has a nasty habit of corrosion build up inside. The hot is worse than the cold.

If neither the hot orcold is working a chunk of corrosion could have travelled to the mixer pipe & blocked it.

Switch off the isolator taps under the sink. take off the pipe attachment to the faucet get a bucket. Put the pipe in it & open the isolator tap. This will tell you if your problem is within the faucet or further down the pipes.
