brs ro question

[Art2249]

I finally installed the sink in my sump room and hooked up the brs 150 water saver today. thats when I learned my tap water has 500 tds. They recommend not using duel membranes over 300 ppm tds. So I decided to take off the extra membrane and just go with one. Now the auto shut off valve doesn't work. Apparantly you need a check valve before the auto shut off. I'm confused as to why the auto shut off works with duel membranes and no check valve. Anybody know about this?

Basically the check valve stops the water from flowing back into your ro membrane when your float valve stops your production water, and the pressure from that squeezes a flap in your auto shut off, that puts pressure on your feed line and cuts off the flow, then shutting off the system. Does one of your ro membranes not have a check valve after it?

Actually neither membrane had a check valve. They both went into a t and straight into the auto shut off. When i took off 1 membrane i just removed the t and hooked it back to the auto shut off.

For there to be an autoshut off there has to be a valve somewhere. It may be in the fitting coming off of the ro membrane housing. Can you provide pictures of your unit and the parts you took off?

Believe it or not I have 2 computers, tablet and a neptune apex i still haven't taken out of the box but I've never owned a cell phone. my tablet isnt charged so no pictures. But i went back through the stuff i removed and no check valve. I just watched the BRS video on installing a water saver and it shows them taking off a check valve and replacing it with the duel inlet T. But I examined the T and blew air through it and it is not a check valve. This is wierd.

My problem is instead of installing an extra membrane I'm actually taking one off. I've already figured out I need to get a check valve. Guess I'll just drink a beer and order the durn thing and forget about it. they might have one at home Depot.
