I use the Kent Marine system as well. I installed it a couple months ago. It has worked perfectly. I actually have it set up exactly like utahtaper. I have two outputs one to the float valve installed on my sump and the other to my work area in the basement for filling containers.

The kit was extremely easy to install. I bought mine at Marine Depot for $40 I think, which included the solenoid, and float valve and all the connections I needed.

I ordered one of the PVC Plastic float switches that "Simple" recommended from US Plastics in place of the "swamp cooler" float valve that I have been using on my RO resevoir, and I'm going to sleep better at night, It only cost $12 shipped, and it arrived in less than a week.

Gary,  Are you saying you use a swamp cooler float valve?

pistonfister,

If you decide to go with the float valve, ( i run a float valve to control my ro unit) I have an extra back-pressue valve. This will shut off the incoming water when the float valve closes.  You could have it for a frag of something or other.

My ro unit flows into a 50 gallon resevoir. I do have a ball valve to shut off the incoming water, but in the event that I forget, the back pressure valve insures that I don't let all the ro water run down the drain.

Hi,

jfinch- "Simple, does your RO unit say it can't be operated at static line pressure?"

Not sure, I toss packaging.

"I could have sworn I've seen RO units under sinks used for drinking water with the valve on the outlet side of the unit (ie at the sink)."

Right, that's ok from what I remeber reading. They use a pressure valve to shut the RO off when the faucet valve is closed. When you get a glass of water the RO turns ON theeeeeeen OFF (much like float switchs can control it). The info I remember reading said that you dont want to have it baaaarely going or flashing on and off every so often. Like what happens with evaporation if you turn on the RO with a float valve and walk away. I dont remember exactly why. But I think it had something to do with debris on the screen when flashing on and off. And something to do with clean/waste balances when barely on.

Again, this is just something I've read.

"personally I wouldn't hesitate to use one with stainless parts for make-up water."

I agree. I don't think the steel on the in-line i linked to would even get wet. Even if it were touching, I'd hardly worry. But it would be nice to have an all plastic alternative when I get around to it :)

jordanh-

Thats a nurce right?
