Push fit fitting pressure test

Push fit fittings are now very common, yet some people do distrust them. This video shows how a pushfit fitting was pressure tested on a piece of copper pipe to almost 50 bar (724 psi) before it failed. So for all the people that do not trust push fit fittings you can be certain that they can hold considerably more pressure than you would ever get in a domestic plumbing situation.

The problem us plumbers have with push fitting is the longevity of them. There is never really an issue with these and how much pressure it can hold its more to do with when its left in place and over many years the fitting degrading due to the rubber seal. Unlike a fixed soldered joint where you can have piece of mind, then again saying that I still use these on occasions. Great test as usual! Thanks. 😀

Wow. That's amazing. I was beginning to wonder if the copper pipe would fail.

Big Clive sent me.

I’d have never guessed that high! awesome!

Thanks to Big Clive for linking this!

I was sat waiting and cringing for the screen to go on my tablet, a good test.

Spot on mate
Push fit connections are good enough for anyone's house.
Having used them for many projects I can highly recommend them.
One of my biggest worries was will it leak!
Every time I have used push fit connections they have never failed unless you don't push it home properly.

Great videos. And well done for not adding background music. It's unusual these days to find a video without drumming in the background.

Just put my mind at rest re plumbing my narrow boat, excellent video thanks so much.

very glad you did this test because I used these fitting to re-plumb my friends header tank and also my bathroom... I knew they must be good because they have been around a while but it's always reassuring to know the ultimate breaking strain

I found out how good they are when I went to cold pressure test a boiler and forgot the filling loop was open. One of the lads told me the boiler was leaking and after 'dissing him', I remembered about the test! The boiler had reached it's maximum pressure and the relief valve had opened (correction needed if a 'correct' term is known!). We went and checked every joint on the heating system and it was fine, hence, I swear by them now as I know what they can take (and more so now) Some great tips you keep showing, so thanks for them as you are never to old to learn new tricks.. :)

Very impressive, I am about to use two of these in a place only accessible with push fittings so the test gives me the confidence to carry on.

Great test but I think people's concern with push fit is the lifespan of the rubber seal rather than the pressure they can take. As always great videos, thank you for uploading.

I was surprised how much pressure it took before failing!

Recently had to replace a heater i installed 12 or so years ago, a lot of the internal parts in the Hep20 fittings had become soft and could be crushed between your fingers, i'm just not convinced plastic has the life span we expect from pipework, especially if its under floors or in walls where it could do a lot of damage if it leaked, the repair costs would be well above what was saved on original install over a copper system.

Thank you you have restored my faith in these fittings 💯👍👍

As someone who's never used push fit I found this video fascinating. I'm a convert! Thanks.

Cheers I was worried about my house as it's about 20bar pressure here being near the dam. I still am putting a reducer on to protect my appliances. But glad to see these live up the their name. Good video

[edwarddevon]

I have to cap two pipes off tomorrow. I'm glad I saw this video. Thanks!

[mikezeke]

as a plumber I've been loving these videos

[gazs]

as a plumber who uses push fit on installations im always wary of them. this has eased my mind. thanks. im shocked it took so much. military submarines cant take that much!!

After 12 years in my domestic house, I had to replace a plastic fitting. After conducting my research with 3 plumber supply stores. 2 stores had stopped stocking the plastic fitting and only supplied the old school brass and copper types because of negative feedback
1 store owner advised me to lift the attic floor boards (bungalow house with pipe running over head for the radiators) I was lucky to find 3 more plastic fitting out of 16 ready to slip off!! These plastic fittings expand a little tiny bit over time when the hot water passes through, they are supposed to tighten up again as they cool down. After 12years they no longer tighten up by themself and caused a ceiling leak

I have now replaced the plastic fittings to brass fittings and I expect get around 30+ years of piece of mind out of them.

Great video. Definitely instilling more confidence in the plastic push fit fittings.
