I have recently fitted a Surestop isolating valve, the incoming side is 15mm copper and outgoing 15mm Hep20 plastic pipe, both push fit, the other end of the plastic outgoing is into a 15mm compression fitting. When I previously used Hep20 pipe with Hep20 fittings I remember inserting a stainless steel sleeve into the ends of the plastic pipe - are these sleeves only used as part of the Hep20 fittings or should I have used them both ends of the outgoing pipe from the Surestop fitting i.e. where the pipe is inserted into the Surestop fitting AND into the brass compression fitting? Thanks for any answers.
you need inserts whenever the plastic is being connected to a compression fitting - so if the fitting has an olive it needs an insert
I thought inserts were recommended by all makes of plastic pipe and on all fittings, be they compression or push fit
Cheers tom It just sounded from Sean's post that he was saying use inserts with compression fittings Not really read all the op post so don't know what fittings he is using just thought to mention that you need them in all instances Sorry Sean if I've misunderstood your post
a lot of folks up here only use the inserts when the mating fitting is copper, so has an olive - so the support sleeve really is required - but a hep - hep joint they don't - I suspect it's old habit from the old system and pre their in for sure ridges on the inside of the fittings - none of my hep to hep joins have inserts, zero leaks each to their own eh ....
I don't know what sean has written, i have him on ignore, but inserts are essential on all jointed pipe. if you get a leak ( and it might not leak for a while) h2o/speedfit/polypipe will have no resonsibility as the joint is not made as per MI's http://www.jhplumb.com/system/brand...ginal/Hep20_Technical_handbook.pdf?1279698363.
taken from speed fit pdf manual. Make sure to always use a Pipe Insert when using Speedfit Pipe. This makes the pipe completely round ensuring the best possible seal between the ‘O’ ring and the outside diameter of the pipe. When using Speedfit Pipe with a compression fitting the Insert gives rigidity to ensure the pipe does not collapse under pressure as the compression olive is tightened
so there you have it jinfromdorset, for tips on plumbing, trust the plumbers, for tips on pen pushing others can help,
Er sorry Tom but I gave the 1st correct answer and I'm just a mere diy'er......... When I said 'I thought inserts, etc' I knew they should be used with all fittings, honest.....was just being polite and trying to help the OP But I do get the subtle nuances of your comment !
Cheers tom.plum I only comment when I think I have something to add and believe that my advice is correct Love the emoticon (if that's what these things are called) I would have no idea on how you put that on here so once again, I salute your impressive talents kind sir.....
you're very welcome Dave, that sean is quick to point out any bad advise from others, but goes quiet when he sprouts dung and is corrected, that's why I have him on ignore, he's forced a few knowledgeable tradesmen away from this site with his ' i've got a degree in dung speading', I'm glad a person as yourself can see throu him ,
you will never make me go quiet Tom - everyone here is an adult (?) I can't force anyone away from this site your repeated attempts at restarting the long forgotten discord of the past is noted
