Hunter Genova Pipework

[Nwalky]

I came across this for the first time yesterday, i have seen something similiar in the past when i was an apprentice but that was a long time ago.

Just thought that i would put this up so as to help anyone out there that may come across it. Its plastic pipe that takes cold main, in this instance it was also taking the hot from the combi which had been converted some time ago, i dont know if pressurised hot water bodes well with this type of system but it seemed to have stood the test of time...that was until i had to work on it.

I was changing bath taps, the bath panel was a pig to come off and then i was greeted with this on a Friday afternoon haha. A quick google of it and i was informed that it was pipework still used in America but used for a little while here in Britain. I ended up cutting it and repiping a decent section of it so that i only had one coupling on the plastic.

I used a 22mm compression fitting, used my gland pliers just to take off some excess paint and after a little persuasion the fitting went on, the plastic even took a hep insert which i put in just to give it a bit of rigidness for the olive to bite to along with (of coarse, because we use it everywhere) PTFE for good measure.

When everything was said and done, the fitting worked perfectly and i was able to continue fitting the taps, the cold never needed altered because it stood up to me working on it which i was quite impressed by.

Anyway, i just thought i would put this on because every little helps when someone, somewhere out there comes across this again. At least you know that a compression fitting in the van should get you out of a hole, i do think however that there may be different variations of the stuff which is why i had cut it back to an easier place to work, in case i had to file it or anything, luckily i was gifted with the fact that the pipework ran surface and was horrible in the first place haha

This is certainly easier to work on than heavy guage...god I hate heavy guage...

Looks similar to polyorc, solvent welded pipe installed when there was a copper shortage in the 70’s.

There's an estate near us that was done in this stuff, but only the cold mains. However you can't and shouldn't use compression fittings on them, however if it holds then Wouldn't like it to fail though...

You can still buy the fittings and special glue, with a fitting from the pipe to a female iron. From which you can go to compression.

They go brittle with heat, hence why it's snapped on you. In the lofts on this estate they all go brittle, and none of the hot pipework is done in it.

I have used it years ago on a health authority project for hot and cold water supplies, Hunter Genova chlorinated plastic I believe it was called now discontinued, George fisher does a similar product still , it is joined with a solvent cleaner applied to the fitting and pipe to remove contamination then a solvent type glue applied to the pipe and inserted purpose made adaptors to BSP should be used to convert to other materials never seen compression fittings used ?? , Kop

Don’t know if you’re not supposed to use compression fittings on polyorc, but mwm do one similar to a leadloc, with an insert. Fitted many, without many issues.
