Kitchen tap problem

[kevcrane]

Hi

I am new to the plumbing industry so please excuse me if my question sounds a little dumb.
A guy has rang me to ask why his kitchen mixer tap has water coming from the cold side but NO water coming from the hot side. The mixer tap is a lever type action and runs off a combi boiler. My guess is that it could be the ceramic disk or could it be that it is blocked???

Many thanks

yep could be

need to attend and find out

could be an NRV blocked if fitted

assuming they have HW else where by the way

As said need to isolate water and strip it down to asses it.

yeah, hot water else where in the house

Probably a blocked non return valve. Normally when a cartridge goes on a quarter turn tap it will drip, not shut off all together. Though there is a chance the disc in the cartridge has broken and been left in the closed posistion.

Not a stupid question mate. Should be quite easy to isolate the supply, and check it through.

Also look at the spout of the tap for blockages. Most kitchen taps are a pipe within a pipe, to prevent backflow. I once had a tap which was blocked on the hot with a lump of limescale. Check the spout too!

Definitely not a stupid question. So far 5 replies and 74 views. I'm one of those views because I didn't know the answer either and I suspect a good 50 others didn't know either!!

Thanks for asking it!!
