Post TDS readings

spikehs · #1 05-28-2006, 11:32 PM

I was just wondering what my TDS reading should be at post RO/DI. I have the aquasafe 5 stage RODI. My starting tapwater is about 190... I have had it running for about 30 mins, and it is currently at 28... I figure it should be lower no? Giving that I am just filling up my tank for the first time, i dont want to start filling it up until the TDS is at an acceptable level, would in the 20's be considered high for post RODI? thanks.. btw all the filters are brand new. Thanks!!!

20's is very high. When I set up my aquasafe, my water in was 65ppm and was coming out between 0 and 1.
What is your in tds reading?

I find that I need to flush about 6-10 gallons of RO water through after replacing the filters to get the TDS back down to 1-2.

Have the Aquasafe as well and get 2-4 TDS. Check through the instructions though, there's something about when first setting up you'll get a high TDS from the carbon filter until you run it for a while.

My water going in was about 170-190, and my filtered read .01.

Question, my Di media was green in color when I started using the filter a year ago. Now they are almost all brown or colorless. Does that mean I should be replacing them soon? No change in the way the water tastes though.

Yes you should change out your DI media once it turns yellow/brown, it means its exhausted.

I have about 170-180 going in, and 1 coming out.

ok, well i found one of my sources of the problems... and its pure stupidity on my part!! I had the waste water line going in to the DI, instead of the RO water. So I switched it, and have come upon a new problem. I have a constant stream of water coming out of the "waste" line, and NOTHING coming out of the RO line going into the DI canaster. does anyone have any idea? When i move that black switch to the flush position, i get a really strong stream coming out of the waste line, and a few dribbles coming out of the RO line...

Had similiar problem, constant stream from waste water line and no unit output. After a few e-mails back and forth from Aqusafe was instructed to disassemble and clean the AVS. Did so, didn't notice any debris but when I reassembled flow stopped.

Suggest do all the hook ups as AVS needs back pressure to shut off. Note, if you have a tank it will take awhile before that fills and unit shuts down. If you have the tank and turn off the line to it does the waste flow stop?

I dont have the storage tank for the filter. I have the line coming from the RO membrane , out of the elbow w/ the metallic nut going into my DI filter (but nothing is going into there). Might be a stupid question, but what is the AVS? thanks...
