As always - PH is bound to get the answer quicker than anywhere else!

I'm looking for a replacement flexible hose - for my toilet. The setup (as done by previous owners of the house) is as follows.

Plastic pipe comes through bathroom floor into a isolation valve. Flexible hose goes from isolation valve to toilet inlet on cistern. Condensation runs down the flexi hose and has made it rusty, now having had some of these flexi hoses fail on me previously, I'd like to replace this rusty one before it does too.

Now, finding the correct hose. Obviously, the connector to the toilet is a simple screw on with rubber washer as you'd expect. But the one to the isolation valve is the same as well - i.e it is not a compression joint.

Now I thought I'd seen the correct flexi hose on Screwfix - but can I find it now? Everything seems to have a compression joint on one end.


Anyone point me to the correct one?

Sounds like he's isolated it with a washing machine valve...

B&Q do one that sounds like yours here. That's a 500mm long one - haven't looked to see if they do other sizes.

Or you could replace it and the isolation valve with a combined item for a neater finish.

Was this the one you saw at Screwfix? - http://www.screwfix.com/p/flexi-hose-1-2-x-1-2-x-3...


Another option would be to replace old isolation valve with a flexi hose which incorporates an isolation valve as well - BQ do them as I fitted one for a customer last week. Screwfix do a similar one - http://www.screwfix.com/p/flexible-hose-with-valve...

ETA - Sorry didn't read the last line of previous post

That's the one I saw - cheers. This house is a nightmare of bodges!!

Question about replacing with a combined one though - the isolation end will be compression fitting right? How do these fair on a plastic pipe? I've only ever put compression onto copper pipe which I can understand how the seal works - wont it squash the plastic pipe?

You get a metal insert/collar that goes into the plastic pipe which the comprerssion fitting tightens up on.

Maybe this depends on the plastic, but that's the only kind I've used.

Plastic pipe uses pipe inserts in the end to prevent it being compressed too far and causing leaks. This is the same whether you're using plastic pushfit fittings or brass compression ones.

The downside to compression fittings on plastic pipe is that the olive tends to embed itself in the plastic so removing it is usually more hassle than it's worth, even with an olive cutter. Unless you really need to change the compression nut, I'd leave the nut and olive in place, wrap some PTFE around the olive a few times and you're good to go - it'll be no less reliable for it, and likely more reliable than plastic hose with various cuts and scratches from trying to get the old olive off.

Ahhh! cheers.

Now I just need to measure the fittings I have then as presumably the plastic pipe is 15mm

There's a big clue here. Throw away the flexi-hose and do it properly instead.
