500L Ro Van Mount System.

PMA Window Cleaning

Recommended Posts

I have a 500L RO van mount system.


My PPM has gone up to 3PPM today and I decided to change the resin for the first time since I've had the system. I gave the RO system a good flush out and then left my tank to fill up again.


Ive just tested my water and its 3ppm again??


I still had 1/4 of a tank of water from the last fill up. Do you think that it has mixed together and made it 3ppm. Or could it be something to do with the filters??

That's what I was thinking.


Don't know if it something to do with the hot weather??


I will have to keep an eye on it. Hope it's not the membrane.....

Thanks for your comments guys.


Am going to try and use all my water today and I will check there's nothing sitting in the bottom of the tank.


I could see a few black bits in the bottom so maybe it's that. Once cleaned out I will fill up and see what the ppm is coming out the DI.


It's a strange one this...

Alright Andy,

Got about half a tank of water left and few more houses to do, plus my own house so should have a empty tank by then. So going to try and find out what's up with it tonight.

I empty my tank last night.


Started filling it up again, the ppm coming out the DI was 000ppm.


I kept check it whilst it was filling and it was still coming out at 000ppm


Got up this morning and checked the water in the tank and its 6ppm.....don't know what's going on.

Sorry mate been busy.


Yer it's all sorted now and filling as we speak.


It was a small crimped fitting that was leaking inside the tank.


GREAT after sales advice by Brodex though......10/10
