Changing Kitchen Tap.

[huguybear]

Hello, hope someone can help. I'd like to change the kitchen tap but don't know how to turn off the water supply under the sink. Would anyone be able to advise where it might be located? The blue taps on the second picture are not shutting off the water supply from the tap.

Many thanks.

The blue levers are for isolating your washing machine and dishwasher(?).

You might not have any isolating valves for the hot and cold supplies. Track further down the pipes, they may have fitted them lower down.

If not, you might need to turn the mains stopcock.

The blue valves are for something else.
Trace the pipes upstream and try looking for an isolation valve. If you can't find one then turning off the stopcock might be a good idea.
Are you on a gravity fed system?
Too late!

If you have a tank fed system for the hot (cold almost certainly mains) turning off the stopcock will not turn off the hot water. To turn off the hot you would need to close the valve (if any) feeding cold water into the very base of the hot water cylinder.

Thanks for your reply. No that's a fairly new built and I have a combi boiler.

Thank you. No , I have a combi boiler so the stop clock won't shut the water supply off but I'd rather turn off the water from the isolating valve.

The stop cock will turn off the mains water. Your boiler should have its own isolating valves. Shut those and then run the tap. you should only have about 15cm(?) of water in the pipes to deal with.

No need to touch the boiler isolation valves, as with a combi, the stopcock isolates both hot and cold.

And fit service valves at the same time you change the tap.

Good point. Thanks.

Does the new tap have flexi pipes or does it have hard tap feeds like the ones you have?

Really not wishing to patronise but if you are struggling with how to isolate the water to the tap then you may find it a touch difficult to actually swap the tap out as there may be a bit of alteration needed to get the new one to connect to the supply. Those HEP fittings may need altered and you will need a key to remove the current pipework for starters.

Typically, the water shut-off valves are located under the sink, near the pipes that connect to the tap. They're often small valves with a lever or knob that you can turn to shut off the water supply. However, the main shut-off valve is usually located where the water supply enters your home. It could be in a utility room, basement, garage, or even outside your home. Once you've shut off the water supply, you can safely proceed with replacing the kitchen tap. Just remember to open a tap somewhere in the house to relieve any pressure in the pipes before you start working.

If you're still having trouble locating the shut-off valve or need further assistance, don't hesitate to reach out to a professional plumber. They'll be able to help you identify the correct valves and ensure the job gets done safely and efficiently.
