Hello,
Here's a picture of a bathroom sink tap. I think it's by Pegler.
I'm struggling to find out how to remove the headgear. Pulling the handle hasn't worked, although I'm wary of using too much force in case that's the wrong thing. There's no retaining screw visible. It's not obvious that the end cap pops off where the gold rings start. Can anyone suggest what to try and the level of force to use?
I want to get to the innards because it's dripping... It's quarter-turn on a typical domestic combi-boiler installation, the output is divided; hot water comes out the left half of the spout, cold the right half.
The hot side of the tap has started to drip. The frequency has slowly increased, I'd say it's now faster than a drip a second, although it varies a little through the day. Sometimes the tap will start a high-pitched whistling. That can continue for about a minute and will then be replaced by a fast noisy vibration in the tap and pipework as if it's some kind of water hammer. It can be quelled by twisting and holding the handle in the off direction, even though it's already fully off, but if you let go the whistling/hammering noise returns instantly.
So instead I have to heat up the body of the tap where the handle joins it by turning the tap on for a bit, the handle then becomes stiffer to turn, presumably due to expansion somewhere, and when returned to off the noises will have stopped and the dripping will have slowed. The dripping soon returns to normal as the tap cools. Obviously, a dripping hot tap and a combi boiler is a bad combination, the boiler is firing up every twenty minutes.
This is my first faulty ceramic disc tap. Is this typical of a failing cartridge? Can I temporarily swap the hot and cold cartridges to check the fault also moves, even though that means the taps will need to be turned the other way to normal?
Thanks, Jack.
