ᐅ Combination of Existing Composite Pipes with New Ones

Hello Dear Community,

I am planning to move my bathroom to a new room and therefore need to extend or reroute the water pipes. For this, I bought a press tool from Rems with TH profiles. I also bought suitable pipes.

However, I have encountered a problem:
My “old composite pipes” seem to have been pressed using the Rothe system, because on the one hand the pipes are marked with “Alulaser-Plus” and the press profile looks like RN20.

My question is:
Can I simply install a TH press fitting in between, or are the pipes only designed for Rothe fittings?

I would really appreciate any answers.

Very neat!

So you only need fittings with TH profiles – good and affordable ones like Pipetec or similar.

The fittings and pressing profile don't really matter for the pipes. The pipes just need to have the right size. RN is the profile. 20 is probably the pipe diameter. So normal 20mm (3/4 inch) multilayer pipe.
I would just cut it off (of course deburr, etc.) and continue with a Pipetec fitting with TH profile.

For the pipes, the fittings and the pressing profile don’t really matter. The pipes only need to have the correct size. RN is the profile. 20 will be the pipe diameter. So a standard 20mm (0.8 inch) MSVR pipe.

Thank you very much for your feedback. I’m relieved now. I will do it that way. I wish you a great day.
