Plumbing. Isolation valves that don’t leak?

Are there any recommended brands?

I understand they might go wrong as they don’t get used often but it’s really frustrating when you’re trying to fix one thing and the f***ing things don’t close properly.

Do you have a cold or hot water tank? If not then I wouldn’t bother as you can just turn off at the main isolation tap where the mains comes in.

Trouble is the main isolation tap shuts off the water to the rest of our flat and the flat upstairs, so individual isolation valves are preferred.

Because I’m a bit of a plumbing saddo, I have a yearly reminder in my calendar to go round the house and exercise all the isolation valves and all the radiator lockshields. As with anything mechanical, they don’t like not being used.

Oventrop very spendy though

Ballofix or Pegler, but be prepared for nearly £10 each for 15mm

Happy to pay 10 pounds (though the 50 pounds for Oventrop might be excessive).

I think Toolstation have Pegler

Anything other than ball valves has failed for me. Hep2o washing machine valve was useless after c6 years.

I’m now discovering that most isolation valves have compression fittings at both ends. A like for like swap means I need 15mm compression on one end and half inch male thread on the other end.

Never straight forward is it?

You can get flexible tap connectors with a built in valve that are 15mm to 1/2 inch. Dunno if that might be an option.

Search for tap isolation or service valve rather than just isolation valve

Thanks 5lab! That’s almost perfect but I need the half inch connector to be male instead of female.

Yes I saw the tails with built in valve but they were pushfit at the end and tbh wasn’t sure how that works.

Bought this exact one last week. I think it’s the configuration you are after.

Edit actually maybe not as it’s the same connections as 5labs.

Going to try this one

Butterfly valves tend to last longer and easier to turn off
