Speed fit v hep2o

[billonisland]

i have plumbed a kitchen in speed fit and when I lift floorboards find grey pipes which I think are hep2o
Can I join these using speed fit connections
Thanks.

 

[Bonni]

Yes.

 

[durhamplumber]

Yes.

It is not ideal.I would be v wary of it,particularly if its mains water,not sure what your insurance would say in a claim either.

You can and 99 times out of 100 you will be ok.

From a warranty point of view, you will be on your own, they both carry warranties for their own “system” (pipe, fitting and insert) or connecting onto copper, but if you mix systems, then all warranties are void.
Inserts are the grey area, some systems are designed to use stainless steel others plastic.

The way Hep2o suggest joining two makes of plastic pipe without compromising warranty is to use a compression coupler with copper olives along with the appropriate insert for each pipe manufacturer.

Edit. And don’t use any jointing paste on plastic

Indeed,great reply,so,,,,"are ya feelin lucky?"

You will get grey HEP, JG speedfit, Poly & less known/propriety makes, so it really is a bit of a lottery. Just make sure the insert fits reasonably tightly and makes sure the fitting is a snug fit, as they can have different OD's. I'd be wary about using compression fittings in areas that you can't get to.

In an unseen area I would trust compression more than a cobbling together of two plastics with a push fit

The warranty on these systems is worth the square root of fluck all anyway, even if you do stick to one manufacturer for everything, follow their testing procedures to the letter (they can tell whether you have or not) and jump through whatever other hoops they want you to. If a fitting fails, and you can prove beyond all doubt it was a faulty fitting which didn't look faulty when you installed it, all you get out of it is a new £3 fitting. There's no cover for the thousands of pounds worth of water damage caused by a fitting blowing off - you're on your own with that.

Probably best to stick to the same inserts as the pipe manufacturer to ensure the pipe is correctly supported, but the fittings all seal onto the outside of the pipe, which has to be 15mm (or 22mm etc) so that makes no difference IMHO

If you want to be bulletproof re. connecting Speedfit to Hep2O, and you have the space, make the transition with short piece(s) of copper, using Speedfit fittings on the Speedfit side and Hep2O fitting on the Hep2O side.

Can’t agree with that, we were on a site where a couple of coils of pipe that had a manufacturing defect were used, resulting in problems during testing, manufacturers technical support engineer came out did a report and covered all costs for stripping out, replacing and all repairs to plasterboard and flooring.

Some warranties cover the cost of the fittings etc, others are insurance backed. Go with the “cheap” stuff and take your chances.

Thanks everyone. I think the idea from old buffer #10 seems to make the best sense. Many thanks to you all for quick replies. Much appreciated. Bill.

Isn't Hep20 polybutylene?

Given that it is banned in the USA, I had always assumed that PEX was the better option. It seems to be chlorine in water than causes the PB to fail. That said, in my "non-plumber experience" I am not aware of cases of Hep20 pipes blowing up on this side of the pond.

Hep2o is Polybutylene as is Polyplumb and Speedfit Layflat

Thanks. I had assumed that the regular Speedfit is PEX, am I mistaken or is the layflat a different product?
