RO/DI Question

[michaelm2431]

I just hooked up the Kent Marine Maxxima Hi-S 60 GPD. Does GPD stand for gallons per decade? I've had it running for 2 hours, without the last filter in as per instructions. I'm getting 1 drop for me and 60 for the drain. Does a half a cup in 2 hours sound right? My water pressure is at 51 pounds, no kinks in the lines, no leaks, and no air hissing. Is this how fast it's gonna run till it's broken? Thanks for you're help. Mike

I thought that I had a problem too. I am running a Water General RD-102 RO+DI 6 stage and measured 1 gal filtered to 4 gal wasted. 4 gal filtered per hour. TDS in is 112, out is 0. I was told that if your TDS is high the more water will be rejected. Do you have a meter?

No meters.

really, 1/2 cup in 2 hours? thats not right, in 2 hours i make about 4-5 gallons. can you adjust the amount of waste water being produced?

[michaelm2431]

I don't see any addjustments.

[robszar]

go to depot and buy a in line shut off value, turn that sucker 1/2 way. it will cost you < $5

an buy a tds meter, there cheap, like $20

[michaelm2431]

Put the shut off valve on the waste?

[michaelm2431]

Would that give me more flow for my good water?

[robszar]

it worked for me, waters got to go somewhere...

[michaelm2431]

It won't go all over my floor, will it?

[michaelm2431]

It say's I have to throw away the first 12 gallons. Guess I'm not doing a water change till NEXT week.

[robszar]

nah, i put a shutoff valve on my waste line and turned it down a little, my pressure went up and i was making double the amount of "good" water. i think its suppose to be 5 to 1 adjust it so your making 1 cup of good for 5 cups of bad

[michaelm2431]

What did you use, an ice maker valve?

[michaelm2431]

What would happen if I took out the Flow Restrictor valve?

[Whitebird1]

It should have a auto shut off that works with pressure and a Flush valve that connects between the waste water line and your RO canister. The Flush valve in the off post will create pressure to the membrain, in the open. will flush the unit creating very little product. Buy a meter. 20$

Thanks Guy's

[robszar]

1/4" ball valve, yes it will fit on your fridge water line as well

I could have bought a better 1 like your'se, and had money left over for a nice coral.

[Whitebird1]

Not happy with a purchase, send it back! I asked on the NJ club and they helped me out. I had no Idear what to buy. Good Luck!

[michaelm2431]

I should have asked first, but was in store and knew i needed 1. Figured to get best 1 on shelf. I cant send it back,it has 3 hours on it now and made cup and a half of water. I'll try the valve tomorrow. Thanks. Mike

[moose8721]

The fact that it has three hours on it and has only produced a cup and a half of water sounds like as good a reason as any to send it back.

[maxpower39]

make sure the lines are run correctly...the directions are not very clear...
i hooked my first kent 60gpd RO up incorrectly and didn't realize it till i got a tds meter...

[Sk8r]

Make sure the receiving vessel is lower than the RO/DI unit: it doesn't send water uphill fast at all: I was three days figuring that out.

[michaelm2431]

The hoses were attached already. I was running the water up hill. I had 5 gallons tonight. I called Mfgr. He said that it will take 10 days for complete membraine hydration. Thanks. Mike
