booster pump needed?

[Mschmidt]

I just hooked up my shily new BRS 4 stage rodi (150gpd water saver (2 membranes)) unit to replace my impulsively bought ao smith ro unit (haste makes waste). As it turns out, my supply provides a pressure of 67psi at the intake to the (first) membrane. I know the indicated low end is 50 psi for getting by without a pump, and I got the pump when I got the filter.

Now for the question that surely wasn't obvious from the title, is the added 10psi worth the cost or am I better served returning the pump and spending the money on new coral or the new baby that's coming?

Return it! I get 35 psi- i need it! You don't mate! Spend it on the baby..

I wouldn't worry about the pump if it were me. You have plenty of pressure.

I would run the pump, but I like to make the water as fast as possible. I run dual membranes and 80 psi.

I'm surprised you only get a 10gph increase with the pump...

I get 65 from the City, but I have my booster set to 100psi and I get a lower TDS with the higher flow. Also makes water faster.

Is it the Aquatic Pump. Their is a little allen head screw at the front bottom to adjust pressure.

10 is all I need to stay in the range provided "over 80psi and you risk the integrity of the housing" or something like that. It's also not hooked up yet.

It is the aquatec.

leaning that way.

I run dual membranes too (membrane 2 filters the waste water). tds pre DI is 6ish (on the first 3-5 gallons I've run).

I get 65 from the City, but I have my booster set to 100psi and I get a lower TDS with the higher flow. Also makes water faster.

I like the faster water making. push it to 4.5 gallons per sitcom up from the 3 it is now.


I'd like to drop tds out of the membrane from 6ish. If that would make DI last longer and would pay for itself in a yearish I might keep the pump. But as of now, thinking return it.

Some comments:
two membranes plumbed in series is only advisable if you have soft, or softened water.

you can crank the pump up over 80 psi if you have the pump installed after your prefilter housings.

Thanks! I'll be saving this for later.

No. with the caveat being that we don’t know your water quality going in or how much you’re making a day.

There are too many factors involved to determine what benefit you will see and it is too difficult to know if that benefit is “worth it” to you.

We live in a drought stricken area and water is expensive (we also use a lot between landscaping and pool) so the $50 or whatever for the pump is the responsible thing to do (for me) despite the fact our incoming water has a TDS of maybe 50?

So not advisable to cut wastewater production? Ideally I would be better than 3:1.

drinking about 1.5 gallon/day (post RO pre DI). tanks get another 10-20 gallons a week. 145 tds pre RO, 6 post.

This raises a good point on the social responsibility of being the most efficient I can be. No drought here in MD but just cuz I have water doesn't mean I need to waist it.

Your outgoing water is 6? I would view that personally as an issue and work to lower that to 0. A booster pump may help, a second resin filter may also help.

Water conservation and electrical conservation are important in our hobby for sure!

out of the membrane is 6. I get 0 out of the resin.

Then in my unprofessional opinion, you’re good to go!
