How to fit an isolation valve ⚡

How to fit an isolation valve into pipework using a quarter-turn compression isolation valve.
Isolation valves are normally easy to fit as the majority of them are compression or push fit, you can get valves that require soldering, but they are not as common and can be tricky to install without damaging the isolator.

Isolation valves are useful, because you can service items without having to isolate the water to the whole property. Ideally when installing a compression isolation valve, if you tighten the nut finger tight, then give the nut ¾ of a turn using a spanner/wrench that should be sufficient.

When one isn't a plumber, these videos are so super useful. I'll need to get good at DIY because we've bought a house that needs a ton of work.

Thank you. Appreciated.
Naturally a lot of plumbers don't want small 10 minute jobs even as they would pass by the house anyway. Our old plumber retired and it is almost impossible to find a reasonably priced plumber who won't charge more than half hour call out and parts. Now I have found the parts are only a small amount anyway but our old plumber only charged £30 for small jobs. That was a lot of his work and he did well taking on the small things.
One in Chichester through a checkatrade quoted almost £100 for a tap washer replacement. Checkatrade has really gone downhill and I shan't use them again after our last two experiences. I don't know how they are getting high reviews. The one star reviews are horrendous now. Seems they were bought out.

This video saved our Christmas! It's a long story, but this helped out massively! Thank you, and Happy Christmas!

Quite helpful. I attempted replacing mine before watching this video but it was terrible as water was leaking. After watching your video i did the second attempt and there were no leaks. The problem was that on the first attempt I just placed the valve and tightened the nut without pushing the valve further enough. 😂😂

Thank you so much. Finally fixed my leak and installed a new sink… and all thanks to you 😃

👍🤓👍 full bore version is the way to go wherever possible great video as always👍🤓👍🍰

Great video and really helpful info on the flexi tails. You have the knack of explaining things that other youtubers leave out. In this case the reason for flow direction. I bought pegler iso valves recently and neither had a direction of flow arrow. Your explanation of how to work out the direction helped. Thanks!

You know what? I´m subscribing from now on. This was informative enough to feed a family of five. Luckily I have no children. I will use my new knowledge very soon to replace a leaking (as in internal which causes a toilet with a broken sealing to have the water tank filled up within 10 hours even though the valve is closed) isolation valve.

I thought I knew everything about fitting isolation valves but that tip about the weeping screw was new to me, thanks! I have replaced valves in the past for that problem.

First time participating in any plumbing and your instructions and tips really did the trick. Thank you 👍

[edwardedward]

Thanks ! I was trying to find out how to connect a flexi tail to an isolation valve I now know you need the flat ended one !

[richardpowell]

Saving me a ton of money as I'm going to give this a go myself. ill feedback when I'm done.

Thanks so much for all your videos. You have helped me out of many sticky situations

V.useful video, with clear explanations and easy to follow. We ended up using 240 wet and dry sandpaper instead of a deburrer as we couldn’t find one in our DIY shop and it worked well.

Good instructions and informative video 👍👍. Was shocked at the size of that valve, would not like to change them too often.👍

The flat faced straight isolation valves look great, never seen those before and have sometimes struggled when connecting the flexi-tail hoses to get a reliable seal. Cheers for the tip, I'll be looking for some of those as I usually keep a few in the tool box for whenever changing a tap etc, having the isolation valves makes all future maintenance so much easier :) One tip I can share is if you're considering using the handled isolation valves, is to check the screw that retains the handle with a magnet. I've found a large number of these that use thinly plated steel screws that rust quite quickly, a replacement stainless fixing is a cheap fix and saves the handle falling off when the steel fixing rusts through, especially when you need to isolate a pipe in a hurry and the handle is missing due to a rusted fixing :) Keep up the great content :)

Great video, really informative and a great source of information for helping me to replace the isolation valves in my shower and toilet! Thanks.

[freemindmtb]

Had to replace mine as shredded the screw ....first ever time doing plumbing thanks man all worked out

[playeroflife]

Great video. Ty. I was dreading installing a new basin. But Ty for the clear instructions.

Good video and well explained. Why would you use a non full bore over a full bore?
I am planning to put an isolation valve on a pipe that feeds the toilet cistern, would full bore be better here or non? Space isn't an issue.
