Do I need a booster pump. Pictures attached..

Busa1340 · Jan 22, 2016

Ok so the RODI unit is up n running. TDS coming in is at 009...TDS coming out is 000. All well in good but two concerns. Pressure is about 30psi or right around and my DI resin has a water line. Do I need a booster and do I need to worry about that water line. See pics n let me know thanks!

Edit I'm a idiot had the feed and drain line mixed up at 42psi now is this ok? And how about the DI?

Busa1340 · Jan 22, 2016

11 TDS in.. 000 out

Busa1340 · Jan 22, 2016

Got better pressure

Your fine with the pressure you have now. I have that as well. Also you can get the air out take your wrench that came with your unit and loosen the canister and turn it on it'll push the air out then just tighten it back up[emoji106][emoji4]

@AZDesertRat should be able to fill you in.

Busa1340 · Jan 22, 2016

Thanks but once again I feel stupid I should have tinkered a tad more lol I had the flush valve open now it's closed and I'm getting over 70psi lol j

Throw the flush kit away, it does nothing but give you a warm fuzzy feeling, waste of your hard earned money.
The TDS readings you have are post RO and post DI. What is your tap water TDS and your exact measured waste ratio?
11 TDS after the RO is pretty high unless your tap TDS is 500 or higher, you should be seeing around a 98% reduction in TDS from whatever the tap is. Also what is you water temperature as it also has an effect of membrane efficiency, the colder the water the lower the RO only TDS will be.

Busa1340 · Jan 23, 2016

Ratio is 4 to 1 .. And I'll just leave that flush kit on it. Not a waste of my money I got the unit for 129$ Black Friday deal so flush kit or not it's whatever. The unit is hooked up via my washers cold water supply so for exact temp I'm not sure but.. It's cold..afye running for a bit I'm now getting 8-9 TDS in and 000 coming out.. At about 71psi.. Seems to be working good.

AZDesertRat · Jan 23, 2016

Temporarily move one of your TDS probes to the incoming tap water. Without knowing your tap TDS you have no idea if it is working well or not. 8-9 could still be high, my tap TDS is around 560 now and my RO only TDS bounces between 2 and 3. For every 2% you can improve the RO rejection rate you double your DI life.
Did you measure the 4-1 waste ratio or is that what it is claimed to be? Measure it to be certain as often they are way off.

Busa1340 · Jan 23, 2016

Ok will do and just curious what's the difference between the TDS meter water coming IN from testing the tap water? Would this be the same without un hooking up. And yes I'm just going off what that unit is suppose to produce (most likely different) as you say. I do notice this unit does produce water slot faster than older units I've had. And are you saying even if my TDS meter is reading 000 out it could be higher? Thanks for the feed back also great help!

The "in" meter on the brs units measures the tds of water processed by the first stages and the membrane. It is reading the water coming into the di stage. To make sure your membrane is functioning properly you need to know the tds of your source (tap) water to compare to the reading going into your di.

None, I am or we are just surprise your in coming TDS water is less than 20, or 11 as you said ,.

Ok gotcha I mean do I honestly need to test this way? Not a problem but I feel if I'm reading 000 out I should be fine correct?

kschweer · Jan 23, 2016

I would. Unless your tap tds is extremely high the number going into the di is a bit high. It's really up to you. If the membrane isn't working property it may tell you that you need to adjust your waste ratio.

AZDesertRat · Jan 23, 2016

The IN probe measures the TDS after the RO membrane which should be removing around 98% of the tap TDS. You really need to know the tap TDS to have any idea how well it is working. I never recommend inline meters for a couple reasons, one is they lack the accuracy of an equal priced temperature compensated handheld TDS meter and another is they limit you to two readings with that meter and a RO/DI has three places you need to be monitoring.
You also need to know the actual waste ratio and whether it is correct for your water conditions. A measuring cup and clock or watch for exactly one minute from first the waste line then from the treated line will give you the ratio. It should be 3:1 to 4:1 depending on your tap water TDS and calcium carbonate hardness. If you have a water softener your RO will love it.
Without knowing the tap TDS no one can possibly tell you if 8-9 is low or not. To me it is high but that is based on a national average TDS of 250 nationwide. You need to know your tap TDS and your water hardness, both are very important to a RO membranes lifespan and how you set it up.
