Easy R.O solution - for people that constantly forget about the water
 

was at home depot and came across these digital water timer's.

Anyone use these at all for the r.o water ? I would imagine it doesnt even matter what they are made of as this would go inline before the filter.

whoa nice price. Sure beats a solenoid and a controller...wonder how reliable those are...

i would imagine more reliable then me remebering to turn off the water.

Most likely won't work for the low flow that RO units have. Most likely uses a "paddle Wheel" style magnetic pickup and they need a specific flow before they start to turn. Most accurate flow sensors are Doppler effect flow sensors, but they are pretty pricey. I use all kinds of flow sensors at work, With Dopler being the prefered by me, but not purchasing agents LOL

if it's a timer, wouldn't it be based on time, not flow.

Lee Valley has mechanical and electronic ones as well.

DUHH, I totally missed the timer. Just seen hose connections and automatically assumed Flow because thats what I'm working with right now. My bad:redface:

These work fine but you need to take into account it's just a timer. It won't prevent a flood if the vessel you're filling gets full. You should still be putting a solenoid shutoff valve on the RO unit if it's not already there.

What IS nice about timers though is that it can be used to change the cycle time of the RO unit. RO units work better with a long run time rather than lots of little on/off cycles. So you use your timer to say run for an hour or two each day and poof you're set.
