Ro-DI procedure, auto flush valve?

spslove · 11/09/2010, 12:48 AM

I am setting up a new tank and am trying to setup my water making process to be as efficient and easy as possible.

Currently i have a buck eye field suppply RO-DI unit.

My water making process is:

Turn on the water and let it drain through RO until i get 4tds which takes 5 to 10 minutes. Then i let water go through DI and get my 0tds water. I dont use the flush valve. Should i use flush valve prior to letting the water drain through RO? And can i just go straight to getting DI water if i use flush valve.

I have heard of automatic flush valves. So I am interested in getting it for my next setup. It would be great if i can just turn the water on and have it go straight through RO and DI without having to do anything else.

Any help would be appreciated

I emailed Bulk Reef Supply about how to use the flush valve on their units and this was the reply:

The flush valve bypasses the flow restrictor and allows water to pass across the membrane at a high rate. Doing this can flush deposits from the membrane and increase its life. Most run this for 4-5 minutes a few times a month, but more often certainly won’t hurt. All you need to do is open the valve while the system is running. While its running you will experience more waste water and the system likely won’t produce any water, so don’t forget to turn the valve back when you’re done flushing

Thank you, that is a very clear response. I completely understand the use of the flush valve now.
