I have a dripping tap. I’ve turned the cold water off and cleaned/checked the insert in the mixer tap and ll looks good. But the stop cock doesn’t stop hot water flowing. do I need to drain the system (?!!) or is there another way I can do this? It’s driving us mad... combo boiler probably 15yrs old.
Separate hot & cold levers on off feeding the mixer tap or a single lever on off? Do you have an isolating valve under the sink to the hot & cold feeds. What make is the tap?
There is an isolation valve for cold but can’t see one for hot. Atlas aquifer also have another dripping tap (!!) but I can’t see any Allen key or screws to remove the taps so I can get at the cartridge. Both have OK o rings in the sean neck
Is the hot water fed from a header tank in the loft, or direct from the mains? If the latter there’d be some Water storage in the pressure vessel, but not much. If there's a header tank you would need to empty it before the flow stops.
No header tank. so do I jet need to isolate cold then turn hot until it stops? I thought it may draw form the system and mean it empties the rads?
Some combi boilers have a small hot water tank built in (mine does) so after switching off the cold feed you may have to run the hot tap for a while to empty the tank. It won't drain the rads they're separate.
Turn off Combi electric and gas. Turn off Main stop cock in the street if you dont now wear it is. Open as many hot and cold taps and work with a load of old towels. if you've a combi you shoulndt have a hot water tank
Brill I’ll give this another go tomorrow my other taps are mixer, but no sign of how to take the the turn bits off. Reckon I need to take the while tap out?
The tank just takes up the slack period of waiting for the boiler to fire up and heat the flowing water. Without the tank there is usually about a 30s wait for hot water.
As said above, turn of cold isolator under sink, turn off combi, turn off cold feed isolator to combi, open tap on hot until water stops running out, remove cartridge and replace. Should work.
What they said ^^^^ The water to the rads and the hot water should be completely separate circuits. You wouldn’t want to bathe in what comes out of the radiators! Apart from the inhibitors, there’s probably all sorts of black sludge.
