RO/DI problem

[nickxx4360]

I have a Kent marine Maxxima RO/DI 35gpd system. I replaced all the cartridges including the membrane. I used a 75gpd membrance instead of a 35gpd membrane now.

When I run the system the DI clear canister does not fill up @ all. Instead it fills up in the DI cartridge itself ( the Cartridge is the one where you can refill the resin btw). I checked the water with my TDS meter and it reads all zero's.

this is the water flow: sediment> carbon block> membrane>DI canister.

Should I be worried at all? Water flows out of the exit hose fine, it just does not fill the last canister, just the DI cartridge in the last canister.

Thanks

Did you change the flow restrictor when you changed membranes?

Not familiar with the Kent system, hopefully someone will come along that is, but if your TDS is coming out at zero, I wouldn't worry about it as that is the goal

On some systems, the DI canister will not fill completely. My AWIce Typhon actually only runs almost empty when in service but TDS run out at 0.

Thas what happens, the canister runs almost empty, I get a trickle of water here and there. I didnt change the restrictor, I was told by the company that sold me the membrane I didnt need to. If a purchased a 50 and below gph, then yes I need a restrictor.

See if you can contact Kent and get their 2cents about the whole thing.

it's the restrictor, I need one. I have a inline one on my waste line. I need a 75gpd one. Even though it works, I will still pick one up.

Thanks all!!

I guess the question now is: Should I remove the one on my waste line and not put one @ all or get a 75gpd one.

You should only use a single restrictor, and it should be matched to the capacity of your current membrane.

Your issue with the restrictor has nothing to do with your DI housing not filling up. Its not filling because you have air trapped in the housing. This can happen with a new system, or after you change filters, or if you have the tubing leading away from the DI housing such that the water in the DI housing is siphoned out after you turn the system off.

I have the Maxxima myself and like Buckeye said,It should match the 35gpd you originally had.I have the 60gpd.

Flow restrictors are very inexpensive, and it will take you all of about 30 seconds to change it out.
