Quick help on the booster pump

[Adamantium]

Is there a different term for flushing the membrane via bypass of the flow restrictor, and flushing to reduce TDS creep? I just don't want us to conflate the two.

Really depends. My house has low pressure, I was at like 30 before I got the pump, now I am at 80.

I don't know if I exactly follow your question. In my system the flow restrictor is in the waste output of my last membrane which then goes to flush valve then to waste bin and/drain. I open the flush valve then watch my TDS meter until it reaches about 5 TDS then shut the flush valve.

Have you timed how long your RO buddy flushes for. Mine is less than a minute, which is not long enough. I wish it was 5 minutes.

I turn the unit on and the turn on the water, nothing comes out for about 10-15 seconds, so I assumed it was the flushing. Mine is the newest model.

Perhaps my house already has about 75 psi by measuring it out front so that’s why I don’t see much improvement. However, if I remember correctly, this booster pump was able to boost up to 100 psi so that why I bought it.

With the booster pump instructions, flow restrictor was removed.

Sorry, but I wouldn't accept 2 TDS as acceptable after DI resin. You've invested into RODI and a booster pump, get your moneys worth & efficiency out of your system and change resin more often.

Anytime my TDS output was anything over 1 TDS I changed dual bed resin and I was cooking through it every other month. I switched to 3 part resins (Cation, Anion & dual bed) and now I go through Anion only about every 4 months. Cation and dual bed have gone over a year. My tap water is 320, after membranes it's 4, after resin it's 0.

Great lookin' setup you got there.

Hmm, maybe I have an atypical system. I have a bypass valve that diverts water from the flow restrictor, but when I do that, I get no output from the RO membrane. As such, I have a y-valve after my membrane with one direction tapping into the waste line, and another going to the DI. I open the bypass valve for about 30 seconds, then shut it and let the TDS creep come down with all that water going to waste. Then I close that valve and open the one to DI.

Hope that makes sense haha

Not a big deal, really, since my system works perfectly for me. Just wondering if this isn't a typical setup.

Great lookin' setup you got there.

Thanks!

I have a dual TDS meter and I manually flush everytime I make RODI water but I watch the first input probe (directly after membranes) when it gets down around 5 then I shut the flush valve. That's usually 4-5 mins.

I guess I miss understood. I thought you were saying your RO buddy flushed for 5 min. I flush manually also because the RO Buddy only flushes for 30 seconds or so.

The new one only flush about 10 seconds

The new one only flush about 10 seconds

That's probably all mine does too, but I bypass it for 5 min or so.
