Puratek 100 RO/DI Help

HL649 · #1 01-01-2014, 05:13 PM

I pulled the RO canister fittings off and found that the fitting going to the waste line did not have this small check valve on it but the fitting for the produced water did have a check valve built into the fitting. I swapped the fittings around so now both my waste line and produced water line have check valves and my inlet water source does not have a check valve. Everything seems to be working fine.

My guess is that the fitting for source water is not supposed to have a check valve and someone screwed up in the assembly of my unit. All is well now and it appears that I am going to like this unit.

Thanks for all the help. It was much appreciated.

I have one of these awesome units and was wondering how to start the flush function. After filling my reservoir, the 3 cylinders are still full of water. is this normal?

It will flush after it senses that the reservoir is full then once it's done then the housings will fill

I'm just setting my unit in the sink when I need ro/di, then the water tube is submerged in a 5g pail. how does it know when the reservoir is full? I'm thinking the canisters shouldn't be full of water when I put it away.

You need a float valve on your reservoir, the computer will sense back pressure and stop production.

Here is mine installed but not yet plumbed.

It's hooked up to the faucet, when my reservoir is full, i just turn off the tap. Easy peasy. Wondering how to get rid of the water in the canisters. if constant water in the filters is not a problem, then i'm all good. thanx

Membrane needs to stay wet to avoid permanent damage and should be periodically flushed to avoid bacterial growth. You need to set up a float and auto shut off, it doesn't just know when the reservoir is full.
