RO/di machine headache

Craigdillman · #1 09-05-2015, 04:57 AM

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.

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.

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 · #7 09-05-2015, 05:09 AM

tap TDS is 250

Thanks for the help guys I'm going to tackle the rest of this tomorrow (with a bomb and get a real unit for once lol )

Cheers

How long have you had the dial on the flow restrictor cranked all the way in? I'm assuming that there is still some water coming through the waste line?

I use the Aquasafe system with the added drinking water stage and have never had an issue, my incoming water is 55 PSI as we are on a well system. Like anything you have to change your prefilters and the green resin sand stuff ( not sure of the proper name) at least once a year.
I'm into year 3 and have not replaced the RO membrane yet and should probably change it out soon.
