When checking flow rate for a new membrane and pump should the restrictor be in place in the waste line? I measured with it in place and I got 250ml. I cut
it to 1.5 inches. I now get 7.1 ratio. Did I cut it to short? It is a 90 gpd.

Was it a full length flow restrictor? If it came in a red or green tube it was already pre-set.

Yes it was full length coiled up in a plastic bag

What pressure is the pump set to?

The test was designed to be run at 60 psi. I will send you a new flow restrictor. Email me your contact info to [email protected]

Ok I will turn the PSI down

you will need a new flow restrictor either way.

Jeremy,

If the flow restrictor is setup as designed at 60 psi and a booster pump is added, what would be the appropriate procedure to handle that? Should the flow restrictor remain unchanged?

The test was designed at 60psi. We now preset our flow restrictors. We will do it the old school way to get it fine tuned. 4:1 ratio may not be necessary for everyone. I like to fine tune it to where the waste and tds is in perfect balance. Meaning I increase my waste until the tds stops improving. I use my waste water for many different things.

Hello Jeremy.

I got the flow restrictor in the mail today.
I have a 90 gpd membrane and the one you
sent is a 180 gpd. Can I still use it?

Stick the entire flow restrictor in, and then measure the ml/min on the product, and then again on the waste. Set the pressure to your desired amount. I always recommend 60 psi. Setting above that may lead to housing integrity of a long period of time. Measure the tds of the membrane. IF the ratio is 2:1 cut an inch off and retest. I would continue checking to see if my tds improved as I was adjusting the waste line. Let the system run for a few minutes to verify the tds has not fluctuated or decreased in value. If my TDS doesn't improve after the first cut, then I leave it where is. No sense is wasting water that isn't needed unless our hardness is high up there. then a 3:1 ratio is required at a minimum.

The flow restrictor was to long to use with the fast flush valve so I temporarily to took it off. I set the pump at 60psi. In one minute waste water was 1200ml and product water was 180ml. That would be almost 7:1. Now what should I do? Tap water TDS 350 RO water 2.

It's my fault. I thought you had a 180 gpd. I will send you another flow restrictor. email me your info again.

Did you ever send out a flow restrictor

I'm sorry, Jeremy has gone on vacation for two weeks and I don't know who you are.

Please send your info one more time and I'll get the flow restrictor out to you.

Maxcap 90 my tds going in is 136 out of the membrane is 1 assuming the 4 year old tds meters are still accurate. Waste water is 3:1 at 55 psi. This is using the flow restrictor that was set at my old house and was 4:1 then. Do I need to replace my flow restrictor and get back to 4:1? I thought 4:1 was the minimum.
Also how do you calibrate your inline tds meters on the maxcap 90?

Here is the tds solution to calibrate the tds meter. On the back of your tds meter there is an orange screw to adjust the value of tds. We want to make sure that when we put the probes in the tds solution that we rinse the probes off extremely well with di water first. The calibration solution comes in at 342 ppm, so we don't want to contaminate it.
