RODI Water smells

[rayviv]

I have a buckeye system and still fairly new. It works well. My question is; This last batch of water I made seems to have a gas smell to it. I have two 44gal brute cans with a small hole in top for rudi line to go into. Usually I make enough water for a 20gal weekly change on Saturdays. But I made this water and missed the change and went to top off and noticed a gas smell. Its in the laundry room and I thought maybe I was smelling water heater or something but when I rolled brute into front room and took the lid off the smell was coming from water. Has this happened to anyone else? Is it because I did not not have it circulating? Help. Can I circulate it and get smell out? should I trash it?

hmm, I never heard of this. I will look around and see what I can find about this unless someone else knows.

I've had a pump in it since noonish and uncovered and oder seems to have disapated. What is it that about the gas that is in aquariums that collects when pumps are off too long?

How old is the membrane, it seems if they get to old they can cause the water to smell.

Oct. and I've run about 15-20 gal a week and sometimes only every 2 wks. depending on water readings which have been consistent and good. Its not really broken in yet.

[marinelife]

hmm, that usually causes issue but that is new.

I think it is just because I didn't have water circulating and had the lid on it. It seems OK and oder is all gone and tds is 1. Was told it needs longer to break-in to get it down to 0.

[marinelife]

That could be, if it is going away you should be ok.

Update on water. I used that to change about 20% and after reading two days later the nitrates were @ 20. Very unusual for our readings. We are pretty stable. Made more water and did another change of 25-30%. Haven't took reading yet since that was yesterday; But made more water and checked TDS. I was 14 coming out of RODI. Is that too bad to use? I dont understand why it went up. It was @ 1 last check. I have the same unit that Dodd has and its not been used that much. Any suggestions?

Let's troubleshoot it a bit.

First the smell - was it the smell of gasoline? Rotten egg smell?

Now the TDS issue. Turn the system on and let it run for 5 minutes. W/o turning it off, take a sample of the DI water. What is the tds?

w/o turning it off, get a sample and test the RO water. What is the tds?

Then grab a sample of your tap water - what does it read?

When the system is running, how much pressure do you have?
