Has Hep2o changed since 2013?

[Albumen]

I fitted my own kitchen plumbing in 2013. Copper where I could, but mainly Hep2o, using what was the "new" version back then. White, as opposed to the old grey stuff.

Has the white Hep2o changed at all since 2013? Especially the connector release tools (which I've got).

I need to do a small job, connecting to my previous pipework. But it's in a horribly awkward spot, and I may not find out exactly what I need until I'm into the job, with both cold supply and DHW (we're on a combi) turned off. Loads of merchants round here seem to sell it, and a quick fake purchase has lots of "67 available to collect" type responses.

But I don't want to get half way through the job, go and buy a new elbow (for instance) and find out that - "oh, they changed the way that works".

Thanks.

Got a photo of your existing ones?

If they look like this then no they haven't changed.



HEP are known to be stubborn sometimes though when trying to demount and can take the insert with them making them unusable.

Here we go then.

Really glad you asked for a photo. I'd forgotten that I had used some of the old stuff. I wish I hadn't now, but at least I'm forewarned. But most of it was in the white. Why on earth did I mix them, just to save a few quid because I had some old left over, presumably. The only leak I've ever had with Hep2o was when I reused pipework. In which case replacing the old grey T with a new one might be problematic. You can see where that is, hopefully, at the back of the fitted units. I should be able to reach under there OK, but if there's a lot of tugging to be done it could be tricky.

You can unscrew the grey ones and snip off the grab ring. Even easier than the white ones.

Thanks for the replies folks.

Just to explain the photos above, and a couple of supplementary questions please.

There are three vertical pipes. From left to right:

1. Hidden, but you can just see the elbow, is cold supply to mixer tap
2. Vertical going up from the grey T is hot supply to mixer tap.
3. Vertical from white elbow is hot (yes!) supply to dishwasher.

Now, god alone knows why I connected the dishwasher to hot. It shouldn't cause problems, but when our non-cheap Miele had problems the engineer suggested it was sub-optimal. But the location (at the top) is really awkward. So while I'm doing this (which is replacing the kitchen tap), I may as well connect the dishwasher the right way.

Questions:

1. Is there any reason why the dishwasher connection can't just be on the deck, in the void under the cabinet? I'd clip both the supply and the DW hose to the floor to secure them . But it would make that job easier, and more secure, than connecting at the top end. I think at the moment it's clipped to the wall, but of course I can't get at it without carving a hole in the back of the cabinet.

2. There's enough "twist" in flexi tap connectors for me connect the hot and cold anyway I want, yes? I mean the hot and cold supply don't need to be going up the "right" way round. Even better, are there really long Hep2o 10mm tap connectors? (checked, can't see any)

Or this might be my opportunity to drill holes in the bottom of the cabinet, and bring the vertical supply inside the cabinet, so it's accessible. Which is probably what I should have done in the first place.

No problem, the hose should reach ok.

There's enough "twist" in flexi tap connectors for me connect the hot and cold anyway I want, yes? I mean the hot and cold supply don't need to be going up the "right" way round.

No problem, as long as they are connected the right way round.

Not sure what you are looking for there. Do you mean long flexi tap connectors?

Thanks. Is the grab ring on the pipe? In other words, will I have to shorten the pipe a bit? I've got the proper cutters and everything, just that it might change how I manage things.

Yes. I was wondering about long flexi connectors going all the way down the back of the cabinet to the pipework that's just above the floor.

Though the more I think about it the more I think I should get this inside the cabinet, where it's accessible in the future.

EDIT. Though that is a slightly mixed blessing. At the moment if there's a leak, especially a bad one at mains pressure, with luck most of the water would go down the back of the units, and escape to the void under the floor through the gaps at the ends of the floor boards. Whereas if it's inside the cabinet it could ruin the units.

In other words, will I have to shorten the pipe a bit?

No, to take the grab ring off the pipe. Snip the grab ring leaving the pipe alone.

At the moment if there's a leak

Think positive, you won't leave any leaks...

 

[Albumen]

Think positive, you won't leave any leaks...

Yes, I should. And until this "leak" (I can't work out if it's the tap or the tap/drainer junction) I hadn't had any.

If it's not clear, I'm very much an amateur plumber, but I tried to do things properly, investing in the right, and high quality, tools, and being super careful.

Thanks. I must have done that, but for the life of me I can't remember what it looks like. I must have some old ones in my "Hep2o bag" in the loft.
