450 gpd ro issue

I have one of them 450 gpd (3x150 gpd membranes) and I put in new membranes last night.

Since doing that the unit does not flush now when I turn the valve on to flush, also the ppm's are rising.

Any ideas?

Have you reconnected all the JG tunings correctly put up a pic later showing all the connections as this could be the issue.

Thanks mate!

I just got home and had another look and spotted the cross over mistake I made last night, just goes to show sometimes you need to take a step back away from it clear your head and have another go.

I took the night off from kickboxing to sort the issue out and its taken me all of 2 minutes, never mind feet up time!

yes mate "0" and "0"

It was rising quicker between resin changes Thats how I knew the membranes needed replacing, that and the fact they are supposed to be changed every 6 months and I last changed them in December.

Really? Every 6 months? Pure freedom told me every 2 years for mine! Pre filters every few months tho.

All depends what tap tds is going into RO were i live it's currently 79ppm its usually lower and in my case they can last up to 4 years without issue as long as your tds doesn't rise and you change the sediment filter every 12 weeks and if you have the newest type of carbon filter every 6 months depending on how much water you are processing.

Mines around 180ppm, I'm just going off the manufacturer of the filters. They come off eBay.

Before I changed my membranes last time, I dabbed all connections with different colour paints.

So now it’s just connect blue to blue, red to red etc. Simples ?

I take a photo before i change the membranes just incase i mess them up but usually just do one at a time then no mistakes are made, I do have a bit of history with ro issues ?
