MLCP Fittings dripping

[jackyp1234]

Has anybody had any experience of MLCP fittings leaking? I’ve used tweet top fittings on a few decent sized jobs and had zero issues, however I’ve just been to a job I’ve done and 3 fittings had a very small drip on them, crimp gun has been calibrated etc and pipework has been correctly deburred,

Has anybody else had any problems?

Cheers!

What pipe and fittings and size ?

 

[jackyp1234]

Cheers for the reply.

25mm and 20mm, worrying because we’ve just done a big job that’s about to be boarded next week, pressure tested to 5 bar and all seems fine just worried a small leak will happen in the future!

And the same brand of pipe all from the same supplier

yeah tweetop mate.

Never had an issue and installed miles of the stuff fully inserted ? All oring there you using u jaws ?

 

[ShaunCorbs]

Any pictures of the leaking ones ?

That’s what I wanted to hear, yeah using the u profile jaws, it’s in abit of a crawl space which was awkward to work it so I’m wondering if it’s maybe dislodged one of the o rings pushing the fittings on, I love using the stuff so was hoping no one else had issues with the fittings etc! I’ll get a pic next time I go, it’s a very small drip. Not a constant drip more just a small build up on the fitting if that makes sense! Was just abit paranoid about the big job we’ve just done in it but should all be fine. Thanks for replying mate

Just to put your mind at rest I did a test removed all the oring and pressure tested upto 10 bar not one drop held fine

So yes sounds like it’s dislodged one of them and it’s not in fully or something else

You sure it’s not condensation?

Definitely not condensation mate it’s clearly on the fitting, like I say I’ve used it loads and not had an issue but this has got me thinking that maybe the fittings weren’t the best quality even though they seem great, I think we’ve probably just struggled to get the pipe in square and dislodged the o ring, I’ll just have to move on from it I think!

Fittings are top notch mate would chop it out and refit

Shaun,

The job we’re doing at the moment in tweetop, I’ve pressure tested at 5 bar and not had a drop, would you expect a leak to show its self at that pressure straight away.

Paranoia setting in!

Yeah will just do that and move on! Glad to hear you rate the fittings it’s horrible when you start doubting the quality of materials when you’ve installed so much of it!

Oh yes you would see a drop I’m guessing you left it for an hour etc ?
