RO/di machine headache

Is that 120 psi before the prefilter, or like you said, just before the membrane?
Something is wrong with the membrane if you have 120psi just b4 the membrane but you are only getting 10 gal per day. Try back flushing the membrane.
What is the psi after the membrane? What is psi before membrane?
Possibly check your plumbing.
When I change my prefilter for the second time, I will change the carbon as well. The carbon wont clog as fast if your prefilter micron rating is smaller than the micron rating of the carbon.
The ro water to waste should be around 1:4
If your filters are all new and you have 120 psi, then you should get at least 100 gal/day from your system. After using for a while, the filters clog and u will get less

Ooo fancy. So Craig, what's the lowest setting on the flow restrictor that you have?

[Craigdillman]

I think I'm going to chuck this thing out so done dealing with it

Unit is from Aquasafecanada.com

I changed the sediment filter and both carbon filters, I'm getting just under 120psi after those going into the Membrane, without the booster I have like 45ish
Sorry i dont have any other pressure readings after that cause the gauge is inline

I dont have a pic but here is the manual

Page 7 has the flow "restrictor"

flushed the pre filters and they all flushed fine lots of flow


I have the pump and the BRS Duel DI resin so can anyone recommend a good straight RO machine so i can blow this puppy up? lol

Remove the RO membrane and try running it. You'll have you answer in 5 mins.

Edit: How old is the membrane anyway? If all you have to do is replace the membrane, that's a pretty easy fix.

[Craigdillman]

membrane is approaching 2 years probably give or take

What's tap TDS? What size tank are you using it for? Trying to get an idea of just how "used" the membrane is.

[Craigdillman]

i have the dial cranked as tight as it can go for the flow restrictor,

Tank is 150g total water and also there is pressurized drinking water container attached that we use for drinking so its probably pretty used

[Craigdillman]

tap TDS is 250
