Inlet Fitting

[DIYC]

Guys,

I'm redoing my bathroom and have my new toilet ready to fit.

I have 15mm HEP20 pipe with a shut off valve all plumbed in.

However, now I'm a bit confused!

The toilet came with a flexi pipe to attach to the bottom of the cistern, it looks like a tap connector.

The nuts on both ends of this flexi pipe are both 15mm and both female.
Female at one end is fine, as the cistern connection is male.

My question is, how do I connect the other female end of the flexi pipe to my 15mm HEP20?

Many thanks, great site, have found reading other posts invaluable!

If it is easier ignore flexi and connect to your existing with a 1/2 inch tap connector

My question is, how do I connect the other female end of the flexi pipe to my 15mm HEP20?

One of these:

Gas4You - I considered that, but the grey hep20 pipe looks a bit cheap compared to the flexi hose.

I also considered fitting some copper tube to the end of the flexi and then a HEP20 15mm straight connector onto that!

But I thought I'd ask the experts what the proper way is.

Softus has the preferred choice so far, but has anyone any idea where I can get my hands on one of those?

Plumbing merchants round here carry very little HEP20 in stock and have long lead times on ordering it.

Is it me or is HEP20 not used anymore?

Thanks again guys.

There's no one single perfect way, but you might want to consider the best compromise of ease of fitting, ease of dismantling when you need to, reliability, and aesthetics.

Ring around your local merchants. There's a John Guest version of this adaptor, which would do you perfectly well, viz:

I have to order them myself, but I keep lots in stock so if you're really desperate I can send you one.

Er, I think it's you.

Softus, many thanks for the offer but I got one eventually (and then decided not to use it!).

I went with a piece of copper into the the last HEP20 elbow which I've connected to a flexi tap connector with a shut off valve built in.

Now I have a new question, though I appreciate this may be the wrong forum (please don't shout if it is!).

The pipes in my bathroom now look like this...

I just want to check what (if anything) I'm supposed to earth?

The copper pipe top left goes into the ensuite (room next door) and is the original pipe.

The copper pipe at the bottom goes into the airing cupboard and looks to come from the loft? again this is the orginal pipe.

The copper pipe top right is the small piece of copper I used to connect the HEP20 to the flexi tap connecter on the toilet.

The rest of the pipe (in the middle of the piccy) is HEP20

Do I need to earth any of the pipes in the piccy?

I'm assuming you don't need to earth plastic.
I'm also assuming the original pipe work is already earthed.
I'm just wondering whether I've broken the circuit though by putting a chunk of plastic inbetween the copper at the bottom and the copper top left?

What about the bit that goes to the toilet - or is that too small to matter?

Thanks again!

C.

Best to raise a new topic on the Electric UK forum, and include a link to this topic.

You'd have difficulty, because plastic is not a good enough conductor.

I'm also assuming the original pipe work is already earthed.

It's best not to make assumptions like that.

Clearly you have broken it, but whether or not the plastic needs to be bridged is actually the question.
