How to orient elbow adapter correctly?

[JStracks]

Hello,

I'm new to plumbing so there may be an obvious answer to this!

As you can see in the photo below, on the cold inlet of this mixer unit I have used an elbow fitting to ensure the hose is straight without any bends necessary. However when I try to use the same elbow fitment on the hot inlet, when fully screwed in and tight the fitment faces up rather than down where I need it to.

Any help and advice would be great.


Thanks all

Sorry to say you can’t install that mixer on water regs (uk water laws) as it’s in vicinity of a cat 5 appliance eg toilet the mixer also must comply with cat 5 regs

It’s a bidet unit so not sure where else it should be installed other than beside the toilet. But ignoring the regs for a second, do you have any advice about the elbow?

More layers of ptfe to make a cone on male fitting so its tapered when going in female fitting.

Thankyou - I did try that originally, but seemingly no matter how many wraps of PTFE, it it doesn''t make a difference to the final orientation

You don't necessarily need to tighten it till it stops though, do you?

Getting back to Shaun's point, if you can put the end of the hose in the WC pan then it is essentially an illegal installation under UK law... unless you supply the water via a break tank to protect the mains (your neighbours - not just you) from possible contamination.

You can have an actual bidet next to a WC, but what you have there is a kind of hose thing you use while sitting on the loo.

I see - the bidet does have backflow prevention valve to help with that- but as I understand, still technically not up to regulations. What is the real world risk of this? I'm not arguing, genuinely curious.

Regarding the not tightening it until it stops, I tried to stop turning it when it reaached the correct orientation, but it was still fizzing/dripping considerably - would the best bet to be put even more PTFE on?

more PTFE

At the moment with the sorry state of PTFE being sold I'm using at least 20 wraps, then run your finger through the threads gently to stop it bunching up and being pushed out when winding it on.

Don't forget that even a hair of a turn anti-clockwise is enough to cause it to leak (quite frankly if you did this by accident you didn't have enough ptfe on in the first place)

Gotcha- I'll give it a go - thankyou.

Regarding the water regs - it's not up to code without an ai gap/cistern for each feed as I now understand. I think a none return valve on each feed is the most I can do, I simply don't have the space for anything more than that. Provided it isn't left submerged in the toilet pan for a prolonged amount of time AND the none return valves don't fail, I think the risk is practically none existent?

I’m gonna sound pompous but as industry professionals, we have a duty to protect our wholesome water supply and in turn public health.

Check valves, like any other fitting, can fail. I’m sure every seasoned professional plumber has come across a failed check valve.

The regs are there to mitigate the risk. I can’t put a % to what that risk is, but it’s there.

I’m also not in the habit of ‘that’ll do’ kind of work, so won’t advise you that.

What someone else does, I’ve little control over and won’t lose sleep. I just ensure that what I do, is done correctly, not only to protect health etc but to also protect my reputation.

I guess my post isn’t much help but though I’d pen my thoughts.
