Hello all,

First post here and hoping someone can help me.

In my bathroom I have a mixer tap on the sink. Individual hot and cold taps. They are a quarter turn so suspect they are ceramic. The problem is with the hot tap.

When it is turned on it can take 10 seconds before anything comes out. It will then run absolutely normally.

Turn the tap off, and on instantly and it will run. Turn it off and wait 15 -20 secs and again will take 5-10 seconds before you get any flow. The wait time seems to improve once a load of hot water has run but is still there.

The hot tap is fed from the same pipe that supplies the bath. (Same type of tap) The bathroom hot tap when turned on has instant supply so guessing not a feed issue but sink tap issue. I'm not convinced it is an air block but happy to be corrected. I think the issue is in the tap. Is what I've described likely to be a cartridge issue.

p.s. The tap does not drip at all.

thoughts???? thanks

proberbly a sticking head gear, as you assume it is ceramic, it coulld also be rubber washered 1/4 turn.
the head needs comming of to determine any-how and greasing up and rewashering.
as there is wear in the head that is causing the sticking of the washers.
 
Thanks Redsaw34.

By way of exploring further I have noticed that if I turn on the hot tap in the sink and nothing comes out, I can turn on the tap on the bath and as soon as I turn the bath tap off the sink tap runs.

Does this suggest a pressure issues and therefore maybe an air block?

Thanks
 
no, this sugests the washer is sticking. the sudden rush of presure from closing the bath tap forces the basin tap open.
ah ah,
