Cheers mark, did you ever get your cards from that place in the end?

Jewelcleaning,

Them black bits are most probably the bits that come off the baffle but shouldn't go through the strainer and that should only happen for about a year after a new system goes into use. I doubt anything is coming through the filters.

So what you are saying is you are just using the R.O to purify your water and then straight into the tank?

How old is the system? There should be a date under the R.O or on a little metal plate on the steel bottom right of the system. How much water has passed through the meter?

Softener - RO  - DI  Resin - Tank

I've basically rerouted the whole thing.

Not sure about age, will check later, is OTT though, if that gives you an idea.

Just checked meter - its at 00137 m3.  Not a huge amount eh?

I've got the waste restrictor from RO turned up so flow out is slower, waste water is at 800ppm

Will having it running like this make the RO not last as long?  If I have the waste flow faster, It comes down to around 200, and the pure water out is slower.

By the way, mains water in is 140-160ppm, pressure around 45psi.

"Does it have a flow controller built on or just a switch for the pump and an R.O type vaulve you open to adjust the flow? Do you rig it up to a battery?"

No flow controller, just a pump with switch, and a switch for the solenoid.  I've bypassed this as i haven't got a battery sorted yet. Just mains water running at the mo.  Filled 300l main tank, just filling some barrels.

Never used back pack but would guess you would spend a lot of time refilling it. Long term use I would worry about wear and tear on back, particularly compression of spine. Probably others would disagree.

Its an old system then 2004 or earlier. I presume you just connect the hose to the first filter. The only thing with not putting a battery on is that it wont shut of on auto.
It must of allways been bypassing the meter with a reading like that.

Its a good static mate and you wouldnt even want to know how much it would cost to fit in a van by Ionics not to mention the extra welding it would need being an earlier model. Get it anchored down and make sure its not going anywere!!

Also I would rather have a high waste ppm so you probably have it set right.

The guy i bought it off didn't like it cos it took too long to fill.  He had it in his van, wrote the van off, and its been sat in his garden ever since.  He's now just using DI resin!!! He didn't like the slow fill time with RO, so gets through a bag of resin a week.  Madness, I say.  Must be making a lot of money to afford overheads like that.  Even then, I'd just leave the tank to fill overnight (with auto shut off of course!) and hey presto.  Much better than just Resin.
