Some of you may remember that a few months ago I had some questions about Buteline, and generally people advised against it. But I went ahead and replumbed a whole house in the stuff anyway and thought I would post my review to help others.
What is Buteline?
Buteline is a plumbing system that uses press-fit fittings using a crimp tool, to mechanically join pipe to fittings.

I'm torn.
I absolutely love the fittings. They are properly sexy-naughty. Really good quality and very reliable once crimped correctly.
But would I use this stuff again? No. It's too much of a pain in the arse to get the crimp tool in tight sections and you end up spending ages faffing about and trying to plan the runs so that you won't get into any situations where the crimp tool won't fit.
I hope this totally unbiased review helps some of you make a decision about this stuff in the future!

- The fittings are small. Much smaller than equivalent push-fit. They are hardly any bigger than copper end feed fittings.
- The fittings are permanent. Once installed correctly, it seems very unlikely that they will ever fail. I subjected a test rig to my own pressure and stress testing and I'm as confident in this stuff as I would be with a properly soldered joint. I can't say the same about pushfit.
- The solder-to-crimp fittings are great. We all want copper going up to our radiators and Buteline have fittings that you can solder onto the copper. Absolutely fantastic.
- The pipe seems sturdier than other plastic pipe and very rigid. I couldn't kink the pipe even when trying.
- The transition fittings (buteline to copper and buteline to speedfit) are superb for joining onto existing plumbing sections.
- No pipe inserts needed
- The joint is made to the inside of the pipe. This means you can get away with some light scoring on the outside of the pipe, which often happens when pulling pipe through joists. I still protected the pipe anyway.
- The size of the crimp tools is a problem. I had a few problems getting the crimp tools between some narrow joists. The smaller ratchet "pro" crimp tool saved the day but these are much more expensive and...
- The "pro" crimp tool didn't create as strong joints as the regular (big) tool. I had to cut down some sections and start again with the regular tool. There are calibration instructions for the pro tool, and they come with a little jig to confirm that the fitting has been fully crimped, but I found the jig pointless as some joints still failed the pressure test even though the tool said it was fully crimped and the pipe was fully pushed home. Re-crimping with the regular tool solved solved the problem.
- The non-standard 16mm pipe is a problem. Imagine you're running your 16mm pipe under a basin and you want to install some isolation valves. Good luck finding 16mm isolation valves. Instead you need to buy 2 transition fittings, 1 for each end of the 15mm isolation valve. At a couple of quid for each transition fitting this makes the job much more expensive than necessary. Additionally, imagine when someone sticks a nail through some 16mm pipe and some poor plumber comes along to solve the emergency, what are the chances of them having 16mm gear on their van?
- The fittings click when the system is heating up. I'm assuming that this is something to do with the metal crimp fitting. This for me is a real problem as one of the justifications of plastic is that it's far less likely to click than copper. With Buteline you don't have that benefit. The clicking is so damn annoying. And yes everything is clipped appropriately.
