Hi Darren what kind of waste tap do you use on the system??
Did you fit the membrane yourself??

[darren9ball]

yeah we did mate and tbh just got a normal round tap from cleaning spot mate whys that

[darren9ball]

only had it 6 months so really hoping that aint fooked mate theres so many factors costing me a fortune lol

[Avo]

There are a number of things that might cause this high tds..
Not fitting the membrane in correct way  causing the rubber seal to twist out of position.. those dodgy pre drilled taps that have a hole preset in them..
70/30 ratio will be close to where you want to be.. start with your tap wide open and flushing keep closing the waste and checking the tds from the membrane and the tds will keep falling until you get to a point where the reading starts going back again up that's the correct way to set up your membrane.. 
If your readings still high after this then time your waste water into a bucket then the pure water and see how many litres per minute you get .. Might be as simple as not enough pressure.

i got a feeling avo
you could be right mate as soon as i changed the flow the reading came down but atm still coming out the membrane 80 ish ,really need to get to the bottom of it sooner rarther than later

What membrane is it?

400 to 80 is unacceptable that's 80% rejection rate and if it's under 12 months old I'd be sending it back.. providing there's no system issues .

[Avo]

Set up your system the way I said to see what's the best possible reading u get.. none of this guess work 60/40 or 70/30  they all run slightly different from one to the next...

I had issues 400 to 59 badly setup factory system but few changes 400 to 20
