RO/DI question... (1 Viewer)

[rxonco]

Ok, in all my 10+ years of doing this, I've always just bought my saltwater and top-off water. Well, I finally got tired of it. I now have my RO/DI unit installed and running. Question would be: Do I need to flush it out in between use? Or, can I just turn it on whenever needed?

Flushing the membrane once every 2 weeks is "supposed" to help extend it's life.

The main trick is supposed to be on how long you run it. Don't run it for a short period of time. If you are going to run it, make up at least a few gallons. I have a big brute can that I fill up when it's half full.

I have a float valve installed for safety only. I only use it to shut off during the night as I usually leave it on overnight when I make water. Only took me 3 overflows to buy one.

Good tip...I've got two 50 gallon drums to fill. Gonna look at getting a shut-off switch. I saw them when I was ordering, and thought "I don't need one of those." Oh well.

Welcome to the RO/DI filter club! One of the best buys I've made. I got tired of lugging 5 gal jugs and buckets of water a while back. Now I just fill my 15 gal jugs once a week and I'm set.

But I need a shut off switch too. I've probably flushed 150+ gallons of RO/DI water due to my forgetting to turn the water off. Even when I've set an alarm, I've missed it. Luckily mine is set up in the bathroom, and the excess goes down the shower drain and not onto the floor. But it is still a waste.

I flush my membranes every time I use them which is about every two weeks. The large spike in TGS from the membranes sitting there really eats up DI resin so I by pass the resin until I get my TDS down to about 2-3 coming from the membranes and then feed the DI cartages. The one thing I have found that helps out the most is a booster pump. The whole system runs more efficient and you make water much faster. I can make 55 gallons of 0 TDS water in about 8 hours.

I'm soo glad i bought a RO unit when i set up my tank. It just so happened thee was a sink right behind the tank. I added a valve under the sink connecting a hose to the RO unit in the stand and i plumbed the waste line back into the sink, It is extremely convenient! In the Manuel, it says to flush the membrane every 6 months. I would suggest to buy a TDS meter and about 2-3 sets of each filter so you don't have to order them later.

Solving the overflow problem is as easy as a float valve and an automatic shut off valve. Both are easy DIY installs.

It's about time. With all that wasted gas money, you could've bought a unit long long time ago.

I know...It's ironic that my delay was out of pure laziness because it was much more of a hassel (and pain...literally) to lug all that water around every week. Much nicer now to just walk out to the patio, turn the nozzel and have 0 TDS water come out of a 50 gallon drum. 8)

I am getting 100 PSI with a booster pump versus 55 PSI without one.

I have the same problem with mine; what is a good brand to get for RO/DI?

I read around some forum seem they use this one.... Think it worth it?
