Plastic pipe

[Fredstudio]

Hey I have some 15mm plastic push fit pipe to connect on to. I think it's either speedfit or hep20. My question is can you use any pushfit fitting and liner on push fit pipe. Or does it have to be the same make as the pipe?

The insert and the pipe should be the same make at least.

It's a very grey area when it comes to warranty, all manufacturers will guarantee their "system" or their fittings onto copper. 25 - 50 years.
Once you start mixing inserts / pipe / fittings you are on your own if there is a problem, they will all walk away from it.

I thought it was the sleeve insert and the fitting that needed to be compatible.

Take Speedfit for example, I don't think their sleeves will fit in Hep2O fittings and similarly Hep sleeves won't seal as designed in a Speedfit fitting. It's all to do with the o-ring position. Whereas pipe is pipe is pipe as it has the same external diameter and I know either sleeves will fit 15mm pipe because I have used both types of sleeve and fitting when modifying pipework temporarily during building renovation. The final system always has the correct pipe, fittings and sleeves to ensure reliability.

Incidently I always check the o-rings are in place since a fitting without an o-ring caused chaos and much damage before it was discovered!

I've mixed pipes and sleeves and it is generally OK. Only exception is Speedfit sleeves which are tight in Polyplum pipe. So now I use other sleeves for everything.

Thanks the pipe is white with black K's on it. Unsure whether this is speed fit or hep2o

 

[Fredstudio]

It's more of a black star. I think this is speedfit?

 

[SandyLyon]

Hep2o tends to have h and v marks alternating on the pipe in Black on Standard pipe and Red on Barrier pipe.

Thanks what marks do speed fit pipe usually have on them?
