I purchased a 5 stage RO
unit a while back. With it, I bought a booster pump & shut off switch, and a drinking water with 5 gal
holding tank. The shut off switch never worked properly.
Bear with me while I walk through the setup.
The booster is right after the piercing conn, then piped to the 5 stages, there is an auto-shut off unit installed from one of these fittings, it goes up(4') to a T fitting under the sink, one way of the T is to the 5 gal
holding tank the other way to the taste polisher then to the shut-off to the tap.
I am on a well with 25 lbs of press, when I plug the booster in and open the piercing valve all works well, I can fill up the 75 gal
holding tanks, fill the 5 gal
under sink put when I close a valve on my product line output, pressure builds up to 110 psi but will not shut off automatically. I have to unplug the unit. What gives here? Any help would be appreciated. Thanks
