Hi all
Really hope you guys can help me. I have put together a static system on a bit of a budget, I got my IBC for nothing and picked up a streamline 600gpd and di resin bottle second hand on eBay. I put it all together yesterday, put new resin into the di, turned the tap and.......nothing! Then I saw the resin bottle star to fill up and eventually it began to dribble out into the tank. But that is now all I am getting. The tds reading on the dribble is between 0-4ppm so it's good stuff but I would say its running at about a litre per hour  we have excellent water pressure where it is and it goes through only a 15m run of hose. There are no leaks in the system and the waste water is flowing at the speed I hoped the clean would flow. The guy I bought it off said he got it a couple of years ago, used it for about 6 months and then had health problems so packed up window cleaning. I haven't changed any of the filters as he said they were new (but I wonder if he did change them and then stored it with water primed through the RO. Any advice or suggestions  would be very helpful. If someone could let me know what systematically process I should adopt that would be great as I am new to all this stuff.
Many thanks
Tim

dont run it with the DI until you know the rest works.

the prefilters could be clogged with algae or anything, did you visually inspect them.
the membranes could have dried out and failed.

you need to check the tds out of the membranes before the DI.

out of your DI should be 000, 004 could mean its shot already

Sorry you're having trouble Tim.
Have you checked all the basic stuff?
Kinks in the hoses?
Waste set?
Are you using hose lock style connectors with water stop spigots in them? If so, the might be catching on the hose? Remove them then try again.
Failing that, break your system down and test each part. Put water just through your DI bottle, full rate? Try your RO. full rate? Try and isolate your filters.

As gto says.

If it's been run, then just left for 18 months all the filters and membranes will need replacing.  Don't forget to wash out all the housings and pipework with a strong beach solution, then thoroughly rinse with plenty of clean water - this will kill any bacteria lurking in the system (of which there will be lots after sitting static for all that time!).  If you don't do this your new membranes could fail in a short time owing to infestation with bacteria.

It's about 9 when it comes out of the RO and goes into the di. The filters look clean but maybe I should replace them anyway. I am starting with water at about 160ppm what sort of figures should I expect after the pre filters or won't it change as they go through this stage.

[Timmy Boy]

I think the water is flowing ok as there is fair rate come out of the drain pipe. When dismantling the unit is it as obvious as it looks ie the the top 2 tubes just unscrew and then something slides out or is there something I need to watch out for. Sorry for the novice questions

[Steve Sed]

Check that the filters are in the right order. A set of filters is quite cheap, so I think you would be advised to change them anyway. But I had this problem and it wa filters in the wrong order.

[Timmy Boy]

I will order some replacements, do I have to stick with streamline ones or do they all fit each other, is there any that I should go for/avoid?

[Steve Sed]

What size are the vessels? It goes by size. My old system had 10inch vessels so I just bought 10 inch filter sets. Googling, it looks like the Streamline ones are too. But best to check.

[Xline Systems]

the streamline 600 has 10" pre filters, you dont need to replace with streamline filters any 10" will fit

[Steve Sed]

Ifit were meIwouldn't replace membranes until I checked the prefilters. Then check what the water pressure is like exiting filters before going into the membranes. Then, with new filters which are correctly ordered, if it is ok into membrane, but slow out, then replace membranes.

[Xline Systems]

the membranes are still ok, it would be more down to water pressure, tap tds or pre filters, the biggest culprit is water pressure. the better the pressure the better they perform.

when you replace prefilters in any system you should open the flushing tap for at least 10- 15 mins and allow water to flow through the filters without going through the membranes,

[Window Washers]

First off I would back flush it for a couple of hours then try again
If that does not work I would hazard a guess it's the sediment filter blocked

How have you connected the ro? You haven't used one of them screw into pipe plumbing fittings have you ?

[Dave Willis]

Just work your way backwards disconnecting pipes. If the water rate is fast before the membranes but slow after then obviously the membranes have had it and so on.

totally agree but the membrane may just need a flush.

[Dave Willis]

If I read the post correctly then fifteen metres is an awful long length of hose to run under pressure.

One quick question without reading every post , have you checked the flush valve is not funny open ? I know that really simple question but just checking

[Frankybadboy]

i do like it when people just say the water pressure is ok


do youself a favour and go by a water pressure gauge,it would tell you and us alot more about why your system aint produceing right

@£10/£15 its the cheaper why to start before replacing filters membrains etc.

I'm jumping on this is a solution.

So we know input tds is 160. If the water is coming out of the pure at a tds of 4 before it goes to DI, the r/o is working at 97.5% efficiency so their isn't a problem there. The r/o should work at between 97 and 99% efficiency.

 "I think the water is flowing ok as there is fair rate come out of the drain pipe." This indicates that too much water going to waste and why I agree with Ian's post.

With your r/o running, measure how much water is going to waste (use a 2 litre plastic milk bottle) over say a minute, and then do exactly the same for the pure, also over a minute. If you have a higher waste to pure ratio than 3 waste to 1 pure, then you need to adjust your waste valve to get the right ratio. Some manufacturers use a small insert that fits into the waste which restricts the waste and forces more water through the membranes, while others use a tap that you have to adjust yourself.

A picture would help loads.
Could well be in flushing mode.
