Replace Radiator Valve with Out Draining the System. Updated. Part 1.

Channels like this are a godsend. Most plumbers want straight forward jobs. I don't blame them most are now over qualified for simple things like swapping TRVs, it's like paying a Consultant doctor to put on a bandaid.. I find it's near imposable to find a plumber willing to show up for small jobs or tackling tricky jobs that chances are could (i.e. the result of our builder deciding to sneekily do the himself). I had 4 plumbers out to unbalance hammering showers, two from the building company, two who worked for us before. The first 3 all went silent for months before vanishing, the 4th (best plumber I've known) to his credit found out what the other guy had done and implemented fix on the first shower he was meant to come back and fix the other one then he went silent for months. Then I found out he'd retired. At that point it had been 3.5 years of chasing, I'd had enough. Using google lens to work out would he'd used to replicated the fix on the 2nd shower myself. But it was super stressful because if it went wrong I'd really be in trouble. It was only possible because of youtube and a ton of google research. In the end it was all perfect even neater than the the 4th plumber because I wasn't worrying about going to my next job.

Sharing your years of knowledge to help people out who can't afford an engineer is very generous. Thank You.

Anxiety levels for a call back coming back down to manageable. Thank you very much. I'll contribute once I'm not running at a loss!

Worked like a dream. Worked well on a lower floor radiator. Thanks for all your helpful advice.

Mark, you are brilliant. So generous with your tips and advice. I am about to embark upon changing a couple of TRVs and thought I was going to have to drain the entire system. This is brilliant advice. I've subscribed to your channel, so looking forward to more from you. Thank you

Excellent comprehensive tutorial, thanks very much, gave my confidence to change a radiator valve.

Great video first time changing a valve saved me money and I got the job done easy enough. Well done 👍

Huge thank you, really gave my the ability and confidence to change the valve on my radiator. Saved me alot of money on a call out and a plumber. Thanks again, really great video :)

This is an absolutely brilliant video! Super informative, clear and helpful. Thanks for taking the time to create and post (both) of these videos. I'm an avid DIY'er and love to have a go at things myself first, so this sort of video is exactly what YouTube was created for IMO. Thanks!

Great video Mark. Your approach worked perfectly for me - thank you. One thing some people might need to consider is where an adapter is used in a TRV (instead of a normal olive) to step down from 15mm to 10mm.

Great video, told me exactly what I needed to know, job completed with no issues

I successfully changed out 3 radiator valves for thermostatic valves based on your earlier video. Excellent videos! Thank you for producing them with brilliant detail and confidence inspiring tone!

Thanks! Your video gave me the confidence to replace a faulty TRV that wouldn’t shut off - the added bonus of knowing what problems might arise helped me be prepared but luckily it was a straight swap

And this is the SHORT video???😯

Damn you, algorithm! Why didn’t you show me this video *yesterday*? Excellent details about locking upstairs radiators and supporting valves. Thank you.

Great Video Mark, I have to replace a Bathroom towel radio, and this has given me the confidence to do this, as I have to change the valves as well.

Thanks for the video. I had to change two valves after replacing an old downstairs radiator which is on a system with a combi boiler and my plumbing has never gone right before. This worked like a charm. Even to the extent that after allowing water to flow out of the existing valves, when i took the valve off no water came out at all. I had turned the boiler off (as the video advises) and all the other downstairs radiators off as well. The lack of water flowing from the pipes gave me the opportunity to remove the old olives and replace the nut Marvellous!

Absolutly fantastic explanation, thank you so much for taking the time to make these videos you an absolute top heating engineer.

I've used this approach for all my smart valves. 👍

Many thanks, great video which covers everything I think I need to know and without boring music in the background.👍
