plastic pipe

[shezzaar]

Hello guys,
We are currently renovating a property. The first fix plumbing has been done in plastic (speedfit).
Today I have been trying to fit the pipes in for a new kitchen in plastic pipe (plumbsure). My connections and inserts are also plumbsure.
Everything works well on the first fix, and the pipes I put it are all strong connections. But when my pipes are connected to the first fix pipe the connections are loose when pulled.
Its all in 15mm pipe
Is this because the pipes and connections are made by different companies?
If so is there a way I can connect both the pipes without having to get speedfit connections, pipe etc?
thanks

You will need to use a compression connector to joint them together. Isolation valves would be a good option for you

If your that concerned use a compression connector. Problem solved.

im only slightly concerned because i was able to pull the pipe off (albeit with quite a bit of force) but with the same amount of force on the other sections they didnt pop off.
to put the issolation valves on the plastic pipe would it be the same like it would be with copper, but with an insert in the plastic?

 

[kay-jay]

Yes its the same but with inserts

Plumbsure are a B&Q brand. You must not mix pipes and fittings and inserts from different brands. Besides the difference in manufacturing tolerance between different brands, you will invalidate the guarantee. If it's done in Speedfit pipe then don't skimp on cost, use Speedfit fittings. A flood could cost you much more.

Compression fittings on plastic pipe in the hands of a novice will only lead to disaster. If you do use these use soft copper olives and the Speedfit insert designed for compression fittings, not the Supaseal ones with the o rings. These are only for Speedfit plastic pushfit fittings. Follow exactly the manufacturers instructions before fitting.

This is very good advise and best you follow it to avoid much pain and suffering in the near future

why not use a small amount of copper between the different brands, this will stop them having to be compatible.

why not rip the lot out and put all copper in :74:

Good idea.......bit like a demilitarised zone :41:

nothing wrong with plastic if fitted correctly, sadly alot of it isnt fitted correctly and it give its use a bad name. We dont slag off copper everytime theres a leak on it or its been fitted badly, we blame the installer.

I hate seeing compression fittings on plastic pipe. It's my pet hate infact.

I prefer to see a coupling, a small length of copper and then the comp' fitting. I know this is another joint, but it's better in my humble opinion.

Totally 100% agree.
