Thread: Joining into existing 90mm PVC pipe

Seems a pity to waste the overflow water into the storm water drain, can't you direct it to somewhere more useful such as swimming pool top up if you have a pool or on the garden? If you can't or dont see the need to do this, then you can buy a T or Y junction joint from Bunnings to do the job.

90mm is pretty thin wall and therefore flexible. If you dig up about a metre either side you should be able to get enough flex in the pipe that you can cut it, lift it up and then spring a t-piece on (with primer and glue of course)

If you don't want to bother digging a hole big enough to spring in the tee, then Iplex makes a repair coupling (scroll down). Basically, a joiner that comes in two pieces, with a locking strip for each side. You'd just have to dig enough to fit the tee and the coupling then.

Didn'trealise they made them in 90mm, only ever seen the 100mm ones. Good to know, although up here you'd probably have to wait more than a week to get one.

The repair coupling is what I'm after, although surely I don't have to order one in from NZ!? I wonder if Bunnings stocks them...?

Don't quote me on this, but I think the local regulations require it to be plumbed into the stormwater. I have to send photos of the tank to claim the Govt rebate and don't want to give them a reason to knock it back. Although the stormwater pipe just runs out into the garden at of the back yeard anyway so it won't be wasted

They could probably get one in. A decent plumbers supply shop would stock them I'd imagine.

Iplex are in Australia too.....

Mate better than a repair coupling, which incidently only come in 100mm, you can but 90mm slip sockets, so the socket fits over the pipe and can freely slide along the lenght of the pipe. You only need to dig up enough to cut in a tee or junction, aswell as enough for the slip socket and your done.

Pretty thin but as brittle as buggery, it will snap as soon as look at it, a handy hint is to cut it with a hacksaw, as a woodsaw will just rip chunks off it, 90mm is a prick of a stuff, thats why I always use 100mm DWV, gives a better job allround.

If you follow Pawnhead's link to the Iplex website you'll see thay do come in 90mm. I thought they only came in 100mm also.

????? hey so they do, I wonder how readily available they would be from your local plumbers supplies........... might suss that out.

Well, after all that, Bunnings sell this 90mm coupling that doesn't have a ridge down the middle like the other ones I have seen. So, it simply slipped over the pipe, I joined everything up leaving a gap, then put some glue on and slipped it back to join up the gap. Easy. Here's a few pics of what it's all about. The only catch is, this little piece of plastic was $5.50!!!
