According to the Instructions, The flow restrictor is to be installed before the permeate pump on the brine in line.  Not after this is the same permeate pump I have Aqua Tec ERP-1000, if you install it as shown in video Pump will not click, clicking sound is important that means pump is working.

Two things done wrong here, flow restrictor should be before the permeate pump, not after. Second, automatic shut off valve should be before the pump (not after) or removed completely.

6 years later and this is still a seriously underated video. Awsome results!

According to actual instructions, This IS NOT the proper way to install this pump, according to pump instructions....just an FYI.

Thanks for this video! Gotta love YOUTUBE UNIVERSITY where you can learn literally anything! I was struggling with how to wire my permeate pump so thanks for this video!!!

Thanks for this informative video .

My understanding is the permeate pump system will not have the ASO auto shut off valve and that increases pressure, so the ASO system may only have 40psi in the tank if the source water is 60psi, but with the permeate pump the tank will achieve system pressure and you'd have a full 60psi going to your faucet and it will make clean water faster.

great video!

Super erklärt vielen Dank, wie ist das, wenn man anstatt eine mechanische permeatpumpe einen elektrischen pumpe benutz? Spart man dadurch noch mehr Abwasser?

Do you need to remove the automatic shut off valve? The aquatec instructions says that if only using a glass at a time leave ASO attached otherwise if using large amounts at a time you can remove the ASO. What's your thoughts? Thanks.

Where can i buy it?

Good job like it

please, do you have a diagram conection pump inverse osmosis domestic, please

Should I install it with or without an ASO valve? Will the pump increase my faucet pressure?

It means that we don't need to use pressured tank to connect to the faucet.

do I need a booster pump in addition to the permeate pump?

should I try the permeate pump and see if the system pressure improves before spending more $ on the booster stuff?

Super explains, thank you very much, how is it when you use an electric pump instead of a mechanical permeate pump? Does this save even more wastewater?

How long is the lifetime?

Do not use ASO if you use permeate. Its better to think about permeate pump as "smart (pumping) ASO".
Permeate pump will shut off output tube by itself, once flow in permeate stops, and do this at very end instead of proportionally (like normal ASO).

If you connect permeate pump together with ASO, there will be conflict: ASO as usual tries to block main input based on pressure in filtered water channel (permeate) - thus choking the performance (=time) when tank fills up, which leads to degrade in permeate pump performance - both in time and power, thus degrading filtering performance towards the end as well - cause it uses the power of waste/drain flow.

So there is still large window for efficiency and  filtering speed!

Still, even with the parasitic effect of ASO, the difference is great. Thank you for the test!
