Ok I’ve got one of these in the van with new filters about six months ago, recently added a booster pump as tap pressure here is about 20psi now got 60psi. The system is designed to make pure water at 60/40ratio of pure to waste. Now this never happens so am content with 50/50 however the following happens.  Pure water is consistent at approximately 1.2 litres per minute, however waste often starts at 1.2 litres per minute but then drops off to a trickle then to zero. This then fowls the ro meaning I have to flush and start the process over again. This goes on a good day for about half an hour and then settles down and all is well, but then sometimes like today two hours later I’m still fiddling and trying to work out what to do. Anyone suffer like this, I can’t leave the system alone ?

i think the best course of action would be to talk to icronic - its their system and would know what thew issues are in fixing it

Their advise now is to take it to one of their service centres, nearest is Harlow, too far!!!

I think those ROs are better run at a ratio of 40 pure to 60 waste.

I don't know what system Ionics employs to restrict the waste, so if you could take a photo of the waste tap I'm sure we can come up with an alternative that you adjust manually - a 1/2" female gate valve. This is the most popular method used by most of the 4040 suppliers.

Try grippatank, they'll charge but they will visit you at home or where you are working
Worth a try if you are losing a days money travelling...

I have a pro 5. The waist is manually set on the wheel to what you want it to be never had a problem with mine and I have 2 systems , are you sure that you have it plumbed up right and not got something connected the wrong way round

[rb4no]

As far as I know it’s plumbed in correctly.  I’ve followed ionics advice insomuch that you have it wound out to flush then close the valve until the pressure rises and stops, then back off until you get the desired ratio. Btw working out the ratio is by getting a measuring jug and timing the flow at waste and at the resin output. Quite clumsy and time consuming anyone use flow monitors like the ones used on hose pipes?

We don’t dump much water as the tds down hear is 90 so I close the valve fully then open it about a quarter of a turn , don’t measure it but guessing it’s set to 80 pure 20 waist . We do some work in Bristol and the reading there is about 380 so we then set it to 50 pure 50 waist . I changed the ro membrain after 8 years and it was still ok but slower filling so changed it . On the 1000 ltr one it has twin ros I have put filmtech ones on it and it has a Grippatank 800 ltr booster pump it will produce 1000 of pure in around 2 hours . It works a lot better with a booster pump

I would say replace your carbon filter and see if it helps the flow going to R/O as the flow slows down when carbon filter starts blocking up and as temperature drops so does water production hence why all R/O problems start surfacing this time of year.

[rb4no]

I’m struggling to upload images right now. The carbon filter is new 6 months ago and I don’t make 100s of litres every day so still in good condition...  after reading DD’s post I backed the valve off to produce 40 / 60 ratio and to be fair it did stabilise! I wonder if this cold weather has a part to play?  Thanks guys.

[NWH]

That’s a good suggestion about the carbon filter if it’s spent it slows it down big time,in the south east if we get a lot of rain the sedement filters can sometimes be blocked in a week or 2.

Finally got some images

dd's post is spot on.

You're clogging your membrane because you don't have enough waste water flowing over it to keep it clean.
Yes change your filters regularly and appropriately to how much water you use/make.

Also that jug thing for measuring pure to waste ratio is daft for such a great looking setup as Ionics undoubtedly are.  It's just a shame they're so expensive to buy and maintain compared to other systems.

Do you have inline pressure gauges? When you find your 'sweet spot' for waste try marking the waste gate valve for future reference. Just a bit of tape or similar in the up position for example. Use the gauges to help though this should be pretty constant if you're using a booster pump.

Also remember to flush on full waste for a few minutes prior to production as it'll bring down the initial high tds quicker. No point flushing afterwards.

It’s all linked to your tds you don’t need to dump 60% with a low tds I have 90 tds at home and dump very little works fine but when in Bristol working tds is 300+ 50-50 pure to waist works well

[Simon Trapani]

Don't know but I'm just down the road in Weston super Mare and TDS is around 300 if I remember rightly (I never check it from the tap these days).

I thought the waste to pure ratio should stay pretty much the same whatever. Maybe less waste if a low tds. I can see how that would work as you're not working the membrane as much.

He still needs to find his 'sweet spot' IMO.

[NWH]

I don’t know where everyone gets this 60-40 ratio it’s more like 20 pure 80 waste,if your waste is setup so your keeping the RO fairly clean you need to put more down the drain.

This is why I don't use them anymore

No it’s not it depends what your tds is if it’s low you don’t need to dump much water if it’s high you do need to dump more as there’s more impurities to get rid off  usually we dump 20% 80% pure simple as that when working in high tds areas 50% dump 50% pure
