My watermain burst.

The emergency plumber showed up and said oh the waters all ready off a the main the leaks stopped ....I'm off toodle pip.

So trying to get the water back on.

Rerouting the water from whence it leaked under a concrete slab (another story about how the insurance company were going to dig up the slab to repair)

How ever what I have is old black poly pipe.

Measuring about 26.8 or a shade under 1 and 1/16th. Od

And c' 21mm Id

It had a compression fitting on but obviously I have no olive and it went direct 22mm copper.

Trying to go to blue water pipe.....but at this stage I'll convert from that black pipe to anything to get the water back on so the girls can come home.

Going to the merchants in the morning but it would be nice to know what I'm looking for before I start. Google's not throwing anything up.

Found these which would likely do......but would you bury it out of site ......although at least if it does go again it'll only flood the garden....not the sodding dining room.

alkathene pipe or MDPE fittings are what you need

If you can take a small piece of black pipe in with you to be sure what you're buying fits what you have

Yeah that's what I'll be doing..... Been through all the fittings in bnq doing the same tonight with a bit of the pipe.

According to Stevenson plastics it should be a 3/4 black alkathene..... But that doesn't seem to correspond to a 3/4 fitting

So this should do ? I don't like things described as universal as per my first link..... Nothing universal was ever good. Not even universal soldier .

Universal or transition coupling. Philmac or plasson are the best makes. They work on outside diameter so you should find something.

I don't know about fittings for alkathene, but most types of screwed pipe fittings have nominal dimensions that are not obviously related to the dimensions of the pipe.

+1 for philmac here. There's a couple of estates round us that are all plastic from the 70s. Bloody nightmare. Brittle and thin walled...
Rip it all out is my advice!

If there is one around your way I have had luck with graham plumbers merchant for some odd waste fitting that wasn't anywhere else. It's a bit of luck as to who is in and what's in stock.

We have the technology now. Time to fix.

Fyi..... No water does not constitute an emergency when it comes to insurance. Even with an 18month old child. *

The leak does..... But as I'm not full idiot I'd stopped the leak immediately to minimise damage.

*Complaint lodged and give the broker their dues the underwriter has had a kick up the arse and compensation has been started. They still can't repair till next week. Due to needing a ground works team......

I guess we can cancel that ground works team.

Cheers plumberists for putting my mind at ease on.the universal joints.

We have water back on and it's routed far better.

Even when I got a response yesterday insurance still want to dig up the dining room floor slab. - no one needs that. They don't need the cost and I don't need to move out for 2 months or more. They need to lift the floor and bring in proper dehumidifiers and dry out the slab good and proper before laying a new floor. Thankfully the sub floor under the house has dried out almost fully. All the standing water is gone and it's just damp rather than saturated.

Hopefully the assessor on Thursday is much more pragmatic especially now that the water is back on and routed sensibly.

Will leave it open for a bit to be sure it's not leaking then bed the pipe and joint in sand and backfill.

Well done and good luck. Insurance companies are buggers.
