On all the other 40” ROs I’ve looked at there’s no fitting that plugs in to the side at the top of the RO so my lid must just pop off with the need to undo it,if anyones knows different could they let me know please.
Thanks

I tried it again this morning and before I turned it on it let me wind the waste right out where’s before it didn’t,it ran full waste again for 30 seconds then on waste only it started leaking from the fitting and then the cap itself.
As soon as I turned the waste valve in for pure and pressure built up it leaked like billyo again,surely the membrane has an issue.

The fitting must surely just need more ptfe tape?

As for the housing & membrane, the o ring can't be sealing properly. Is the housing distorted/dented or can you not tighten it more? Is the o ring split? Water based lubricant help when putting anything with an o ring back together so as the o ring doesn't distort or cut.

That's what I would try anyway. It has to be something.

Where exactly is it leaking from?

Leaking from both sides of that black houseing and the stainless steel fitting that goes in the cap.

Have you not took this clamp off before trying to pop off the black cap? There shouldn’t be a gap-

[NWH]

I’ve just run it to waste only after taking off the metal band bracket and reseating it and tightening it up,with just waste it leaks from that fitting that goes in to the top of the RO or plastic cap then I turn it off.
If I turn the valve in to make water that’s when water squirts out the top of the houseing as well as that fitting but it leaks from the fitting all the same like I said with waste only.

[Don Kee]

Its not leaking from the black fitting when running to waste as you have less pressure running through the membrane.
Once you’re turning the tap to start producing, you’re ramping up the pressure which looks like it’s causing the leaks.

Personally I would say it’s not seated correctly, although I’m not sure why it would work the first time and not the rest.
Either that or something is now restricting the pure causing back pressure.

If it were me (and apologies if you’ve already done it, I can’t be bothered going back over all the posts), I would take the membrane out, rest set it and the reset the end cap correctly with the rubber “o ring” it should have.
Maybe give the brass fitting a quarter turn as well to tighten but be careful not to over tighten, especially if the thread it’s screwing into it plastic.

Those valves are crap btw, be worth changing it to a gate valve if you ever get the chance.

[NWH]

Thanks for that DonKee when I lifted the black cap off there was no O ring on these particular ROs which end does it slide out from what I’ve been reading it’s the waste end first,the weird thing is what could have dislodged the actual filter.
Thanks

That stainless fitting in the top of the cap doesn’t connect to anything inside does it ? I don’t really want to have to take all those 3 fittings apart with the pressure gauge on.

[Simon Trapani]

If you google ‘stainless steel ro housing’ it shows pictures of all the parts including o rings.

You just need to bite the bullet & take it all apart & start again. It’s now Sunday night & you’ve had 4 days off to take it apart.

[NWH]

Thanks Simon lol you sound like an old teacher in all honesty I don’t really want to start butchering anything until I speak to them tomorrow,I was hoping it would be a small fix if they tell me to take it apart I will have to but I don’t want to call them and them say you shouldn’t have touched it.

[Simon Trapani]

I’d still take it apart. An o ring’s come off or something.

They’re just going to want you to send it back. That’s even worse imo.

[NWH]

I can’t think they’d want me to send anything back unless they tell me to open it up and somethings cracked inside,like you say though somethings a miss inside like an O ring or it’s not seated right is my guess the younger bloke there is really really helpful the other older guy is a misery.

[NWH]

When I ordered it all I wanted a complete kit so I could start making water as soon as I needed to it just so happens I still have another static setup at another part of the county I’m using at the moment,it turned up with no hoses from waste to drain no hose from RO to tank in fact no hose I didn’t even get sent a spanner that undoes the Pre filters I said I want everything to start straight away.
I had to ring up next day and pay for pure and waste hose so I could turn the thing on as I don’t have anything where it’s gone.

[Don Kee]

I’m inclined to agree with Simon that I can see it being a “take it apart” jobbie.

Having said that, I agree with ringing the supplier first, if anything at least the problem is logged so that if there is something wrong, they can’t blame you for “tampering”.

[Smudger]

Sounds like an o -ring problem to me..

as said I use a champ housing but here is each end - the first has the gate valve for pure/flush - out the centre goes the waste - you don't undo this end


Second end is the water in - this end you open up to change the membrane - the other side of the cap is large O ring to seal ( this I did damage a year ago and it leaked - I had only pinched it slightly ) there is also a small o ring where the membrane stem goes into the cap - its not happened to me but I can see a possibility of it coming out - which I think would effect pressure
