MLCP questions

[Gone West]

I've not used MLCP before so I have some questions. I've looked at videos of Multipipe and Geberit MLCP systems and the Geberit system looks good for access in tight spaces. Can anyone give me some advice about makes they have used and how easy it is to use an adapter to go back to existing copper or plastic pipe.

With pretty much all makes, it's very easy to go back to copper or plastic as they sell them everywhere. For example: https://naturalgreenheat.co.uk/product-category/wras-approved-press-fittings/transitions-mlcp-to-copper-pipe/

I've used Tweetop, Maincor, Riifo, Uni-Press, etc. etc. They are all pretty much the same. The only thing you need to be aware of is what press jaws the brand uses. Some are available that can accept both TH and U, some are only TH or U and some brands have their own. So when you invest in a set of jaws, just make sure you use the compatible fittings. I have both U and TH as I had one supplier who was very good with one brand and then seriously let me down one time by supplying a huge coil of 32mm that was damaged in transit because they couldn't be bothered to package it properly and made it a nightmare to return it, so I had to switch to something else with reliable supply. But for me it's useful to have both sets of jaws because I use the stuff on all my installs.

With all the systems you have to plan out your job carefully to ensure access. Having a set of angled jaws helps but obviously adds to your setup costs significantly. The advantage with MLCP is you can often bend the pipe to give yourself access, but sometimes you need to use your imagination in tight spaces - e.g. crimp and then thread pipe into place.

Why go mlcp, and not just Hep2O? Hep2O is easy to get, pretty idiot proof (that's why I like it) and no special tools needed. Mixes with copper easily.

used mlcp for my upstairs bathroom rad installs, used geberit press chrome pipe tails.  used mlcp because roll ends left over from ufh install.  Already have a press tool, so found and bought the required jaw from ebay.

 

That said, I'm not sure I'd go out my way to specifically install mlcp, I only did to get rid of them 15-20m sections of pipe I had left over!

I'm only planning on plumbing one room with MLCP because of space for fittings, although if I like it, I might end up using it elsewhere. I was hoping to be able to hire the press tool.

I plumbed my last self build using Speedfit, which went well, and I was planning on using it for the rest of the plumbing here.
