Hey guys, just when I was about to give up, I think I finally figured it out. The pump does work, everything was setup correctly, except 1 thing. There was no flow restrictor on the drain tube. I put a ball valve (only thing I had on hand) and my PSI went straight through the roof.

And yes I tested it with and without the pump on. Thanks for the help though!

After the membrane, on the drain tube. I didn't have anything there so there was no pressure build up.

As soon as you mentioned the flow restrictor I felt dumb for not thinking about it. You might want to get the one made for you membrane. They are pretty cheap. Only a few bucks. That way you get the proper pure-waste ratio.

Yeah, it's always something stupid. haha.

I have a ball/flow restrictor on it right now so I can easily adjust it. Will probably find something a little more permanent later on

Akma, I know hot water is bad for the RO unit. I turn on the hot water a little bit while the cold water is on full blast to warm up the water a bit.

I've always been under the impression the hot water should never be used...not because of heat, but because it has more 'dissolved' metals/chemicals (?) in the water, from the heating elements.
