RO system troubleshooting

[svreef]

Also, I was unable to open the membrane housing to check that everything looks good in there - it’s too tight

Wondering if you somehow got the waste and output lines switched?

I checked and triple checked.

If I did, the smart Buddie would never stop since waste is always open - whereas it stops when it detects back pressure from the product line.

Blue is product, maroon is waste. Yellow is supply and has a tee for the pressure gauge.

Side issue, but 75 gpd membranes don’t necessarily have less waste fraction than 100 gpd, you have to go by the specs for the filter. Also, if you really want to reduce waste water then a double RO membrane is the way to go.

triple... I use 3x 75gpd in series with a 75gpd restrictor... i get 1: 0.75 ratio of good to brine... or better, .

I asked BRS about doing this and their stance is the waste water out of the 3rd is such a high TDS that it isn't worth filtering. I am still not totally convinced given yours and Coral Reefer's experience.

You shouldnt be getting better ratio than that with proper flow restrictor. It does need to waste some.

Have you been able to get the cap off to verify that the membrane is seated properly?

I think I know what’s wrong - it came to me in the shower: the waste line must be blocked. Haven’t proved it, but that would be consistent with all the symptoms.

You’re lying, it came to you on the toilet

I typically get about half to 3/4 gallon of waste depending on day. You think I can get less waste than that?

I’m confused what you’re asking. It all depends how much water you make right?

You mentioned that I can get a better waste water ratio with my 3x75gpd setup than 0.75G waste to 1G RO.

So was curious about that...

No. I said you shouldn’t get any better than that. It’s not working right if you do.

Lmao. I need to learn to read. I read "should " vs "shouldn't "

 

[svreef]

Grrr…

 

[MolaMola]

Grrr…

Have you inspected waste line? Flow restrictor in there?

 

[svreef]

Where can I buy a membrane that’s already in its housing TODAY?
