Title: RO stopped working after move
Post by: Sir Squeaky on June 17, 2017, 08:52:31 pm
Help please 😕
Moved to a new house with an outside tap with plenty of power but getting nothing out of the ro system.
Taken the filters out and screwed them back in but no joy.
Could shaking the membrane pipes about during moving have blocked them or something...? ???

Have you tried taking all filters out and switching the water on to see if it's getting through?
Then one by one put the filters back in to see if any are causing the problems

I bet you 1 million quid that it's low water pressure.

And how would you know that Tosh?  ;D
Seriously though guys, what now?

Shrek's idea is obviously the best one to start with.

Also check that any valves/gates/connectors (even on attached piping) haven't been accidently shut off.

Start at the tap.  Is water coming out? Then disconnect the first connector after the tap.  Is water coming out?  Repeat until you reach the input to the membrane.  Is water coming out?  Then go to the membrane output.  Is water coming out? Then on to the DI.  Is water coming out?  You get the gist.

Then come back and post where the water stops and we'll have enough information to begin giving you answers.

i had exactly the same, there is enough pressure to blow the connectors off when the RO is switched off.
and if the tap isnt open enough the RO cuts out.

i turn on the tap, switch on the RO, then open the tap more to allow the flow

Seems that the flow is right through after disconnecting one by one, but it's a poor flow.
Worked on Tosh's tap so must be water pressure problem.

If I get a booster pump (god knows which one), how much electricity will that use, and how long will it last being on 4 hours a day?

Damn! Squeaky posted just as I put a poll up!

Glad you got it diagnosed Rog.

Hi mate. If it's a roman style about £120 from pure freedom, mine runs 12-15 hours a day with no problems.
How much it costs isn't an issue as what are your alternatives?

They appear to be around £65 on amazon.
Same one though surely?

I use this one on my 450gpd RO.
The water pressure by time its gone through my prefilters but becore membranes is running at 32psi. I purchased this pump or one similar at it takes it to 75psi for effective use on my membranes. I run it once or twice a week filling my 1000ibc tank up and have the pump running for whatever duration. If im filling ibc tank from very very low level than the pump will be on for about 15 - 20 hrs non stop untill next time i need it.

Ok, so on my piddly little RO should I go for the 75gpd pump?
Don't want to risk blowing it

I believe the membranes on these work best at a psi of 70 and above.
So depending on what gpd ro you have, then the 75psi should work fine

I'm guessing it's 100gpd.
That's a fairly standard RO man little system isn't it?
It doesn't need a massive boost, just enough to get it flowing properly

Yep, so that pump should be ok for your purpose. Especially if its lime mine using 1/4 piping anyway.

Have you got the RO fitted the correct way round?
Title: Re: RO stopped working after move
Post by: Sir Squeaky on June 18, 2017, 03:55:02 pm
Yes. Didn't disconnect anything, just the tap

Cheers. I'll trust your judgement and order it then. I'm desperate so have to get it asap

Ive been using mine like this for about a year now with no problems.

I also use a gardiner back pack as a trolley system for the odd houses i cant park near too.  But when that dies, im also going to order the same pump and make my own trolley system as well.

Someone on the Facebook group reckoned you put the booster after the filters and before the membranes?
But I was told after the tap, so it's a better pressure going in like it should be

The first 2 or 3 prefilters (depending on set up) dont require high pressure for them to work, whereas the membranes do.
Therefore to get maximum flow n pressure through them, it is best after the prefilters n before membranes. Another reason for this is not to prevent a reduction in pressure which the prefilters will obviously do, tho not required.

If it goes after the pre filters, it limits the crap going into the pump 👍

I'm sorry but that's a myth, there's absolutely no difference in pressure or flow with having the booster pump before or after the pre-filters.
I've tried both ways,verified with pressure gauges and results were the same.

Thats interesting.
So its a personal preference, each to their own then  ;D
Although when you see what the pre filters look like when you change them, especially the sediment filter. You will be glad it aint going into the pump first

Seeing state of my sediment filter has put me straight off drinking tap water

If I don't push my hoselock connection properly on to my R/O I won't get any water flowing through the R/O, it may appear like it's pushed on properly but needs that little bit of a push to ensure it's on properly. I always disconnect my R/O and flush filters whilst transferring stored water to my van, then connect up R/O and wait a minute to hear water running into stored tank, if not I check hoselock connection is pushed on tight enough.
