Opella plastic plumbing fittings

[PositronicRay]

Hi all

I've just replaced my dishwasher and the Opella appliance valve is leaking, its a sort of plastic compression fitting. I thought it would be as easy as local plumbing new valve and "jobs a goodun"

It seems loads of different types/makes of plastic fittings so not that easy.

I went onto the Opella web site and they don't do this sort of stuff, just bath and shower stuff not the plastic plumbing.

Does anyone know of stuff that's compatible that I can just screw on so I don't need to replace all the fittings under the sink?

[rufusgti]

Pic would help.
All the pipes fit all the fittings, but the inserts are different. So just get a new fitting with the correct insert.

[PositronicRay]

This is what I'm left with about 2cm of stubby plastic pipe (I've put a bit of garden hose over it as a temporary repair)
The T piece sort of screws down over a push fitting/collar

The bloke in the plumbers merchant suggested I just cut off the old valve and just push a speed fit valve on it.
Tried this but it just pisses out water.

What's the best thing to do now?

Phone a Plumber lol.

Has the pipework any scores on that you are connecting onto and have you fitted the correct insert into the pipe

[PositronicRay]

No I didn't put an insert in. I didn't know I needed one (I do now I've googled speed fit)

Even if I get an insert (plumbers merchant bloke did not tell me about these) I don't think I've enough pipe left to fit it into. I notice from the speed fit website that you have to use speed fit pipes, also hacksawing pipes is a no no.
Guess what, I've hacksawed it.

The stubby bit of pipe isn't scored however.

Is the collar on that tee able to unscrew? If so, take it all apart, discard the plastic pipe and replace with a short stub of 15mm copper and fit a compression washing machine valve instead.

[PositronicRay]

The collar does unscrew. Do you just put some copper pipe in and nip it up?

IIRC there is a grab ring inside the fitting ,you need to push it off the pipe in the right directions or your bugger it up,

,I would replace with copper to

[PositronicRay]

Okay

It's important once I start I complete the job. Otherwise the the water stays off and I incur the wrath of Mrs PR.

So unscrew collar, push seal fitting off the end, push it back onto some copper pipe. do up collar and compression fitting on the other end?

Can I hacksaw the pipe?

Yes looks like hep2o fittings, so if all else fails tou can butcher a fresh hep2o 15mm equal T.

When you unscrew the joint and pull the pipe off the grab seal will only come off one way, pull it out over the end where you have the hosepipe if that makes sense.

One you reassemble the T joint you can either push in fresh copper (no inserts required) but make sure its not a rough edge as it will cut the rubber which forms the seal.

Okay I see the hep2o grey fittings are discontinued, although some still available on ebay. I'm nervous about reusing the gripper ring, if anyone can screw this up I can.

I'm hoping to the job tomorrow, do the white hep2o use the same gripper ring?

No, but if you screw it up, you can just replace the entire tee with a new one. You could just put a compression valve on the existing bit of pipe if there is enough sticking out.

Make sure to use a metal insert though.

[PositronicRay]

The existing pipe is only about 20mm and plastic.

You can put compression on to plastic. As long the pipe goes fully into the compression fitting, it will be fine.

So one of these

with one of these stuck in the stubby bit of pipe.

http://www.screwfix.com/p/hep2o-hx60-15ws-push-fit...

I've only got 15-20mm of stubby pipe, will this be enough?

Or should I also get this.

http://www.screwfix.com/p/hep2o-push-fit-equal-tee...

+ some copper pipe?

Am I okay hacksawing the copper pipe if I'm careful and de-burr or do I need a pipe cutter?

I'd get all of the above. You can hacksaw the copper, just file any sharp bits off so they don't snag the o-rings.

That's a polyplumb fitting. You may be able to salvage the grab ring if you slide it off the pipe the correct way.
Other than that, just buy a straight polyplumb coupler and use the guts out of it to aid your repair with a short length of copper and a standard washing machine valve.

Thanks, I'll pick one up.

[PositronicRay]

Thanks chaps for your advice

it took me 10 mins once I had the kit. It was a polyplumb fitting, I bought a spare but didn't need to use it the locking ring just slid off as advised.

I used some speedfit pipe, some speed fit inserts and the speedfit washing machine tap I bought yesterday from the plumbers merchants. All for a couple of £ from Wickes

I should have just fitted a new Wickes/polyplumb washing machine tap in the 1st place and not cut the old one off as advised by the plumbers merchant. "Just hacksaw it off and bung on one of these" is what he said.

You live and learn.

Good stuff. Problem solved with no dramas....
