ro/di faucet pressure: PSI

i have mine hooked up under my kitchen sink. i leave it plugged in all the time. i have a shut off valve to the rodi so that when im not using it i can shut it off so its not wasting water. the device itself stays full.

No need to drain the system between uses. You should use your system at least once a week. You're asking for trouble is you let the system set for long periods unused.

Hi Russ:

Can you clarify what would happen if you don't use it for more than a week and what should you do if this is the case.

Thanks.

Manufacturers say that if the membrane isn't used for more than a week it should be removed and placed in a preservative solution. Remember that everything downstream of the carbon is unchlorinated and prone to biological growth (bioslime, algae).

good looking out russ. thanks for the info

Russ, wouldn't flushing the whole system for 15 minutes before use (after periods longer than a week) get rid of those biological colonies?

I installed mine directly into cold water kitchen supply and get 65-70psi without flow restrictor and when I first got it, if I ever let it stand for more than 10 days the membrane would need to be replaced so I learned the hard way that I have to continously use it...
A few days later I made the rodi system feed into a holding tub with a float valve and connected my ato to it and Voila! I leave mine on all the time and the ato makes it so that the rodi is used every day.

Not likely. Remember you are flushing it with nonchlorinated water.

If the biogrowth is in your membrane, the membrane is toast. They can be cleaned out, but it really isn't practical for these small residential membranes.

DI resin is also notorious for developing biological growth.

Good to know Russ. Thanks
