RODI waste line how long....

[Gseclipse02]

can it be ??? i was talking to eve about this earlier and it got me thinking if i can use my waste water for the yard.... only problem is that its a GOOD 20-30 feet of line that will be needed .... also how long can the DI water line be ?

My waste line is probably 30 feet but I went from 1/4 inch line to 5/8 water hose about 10 feet from the RO/DI unit (it ties into the drain line of my commercial ice maker)
The only thing I have read about the DI line was that it should not have much of a rise. You should be fine with a long run as long as you don't go from the first to second floor.

This will definitely help Ross & I when we get back up and running! Thank JT for asking the question.. You beat me to it.. lol

Yeah, it's just a drain line so the length doesn't really matter. Main thing is keeping some slant to the line so it drains away from the unit. Although at one time I did have my RO/DI in my laundry room and it was on the wall opposite where the washer machine drain was so I had to run the drain line up and over. Probably not the best thing, but it worked ok.

lol well you got me thinking about it ... i hate wasting this much water when i know i could use it ....

i use to fill my 30g with waste water then take it outside in 5g buckets but i for got one of many times to turn off my RODI unit and flooded the house

i had mine running about 50' to the pond in the back and it ran up about 8 feet to go over the top of the deck cover before coming back down to ground level at the pond.

Sometimes I run my waste line into my waterhose which I run to my yard outside and it works great. Other times I have it go in a 30g container then fill 5g buckets and throw it out on the yard and use it to water my plants around the house. I don't think length is such a big deal when it comes down to it.

It runs under household pressure. I wouldn't put too much backpressure on it, but wouldn't worry too much about it, either.

[BuckeyeHydro]

Right - if you put back pressure on it (e.g., some head pressure), you'll change the waste: permeate ratio, and when you turn the system off, unless you have a check valve on the waste line, and depending upon how you have the waste line set up, all the water in the line will run backwards to the RO membrane housing. Remember that this is dechlorinated water - bacteria love it.
