DI Resin Cartridge ?

I posted this in Reef Discussion, but I'll post it here too in hopes of not getting shuffled off the first page so fast!

Hi!

I just replaced my DI cartridge on my Maxxima Hi-S 60GPD. Now when my float valve opens and allows the water out of the RO/DI, the DI chamber completely empties, although the TDS meter reads 0. I'm pretty sure this is not right. I've checked to make sure that its in the chamber correctly and is not upside down or anything like that.

I've put the old DI resin back in the chamber, and the chamber stays full when I run that one, but its an old cartridge and needs replacing.

Do I need to let this sit and absorb water for a period of time, or what am I missing?

Because there is no backpressure on the line and the water flow is slowbecause of the RO, my DI carts never fill up with water either. Just a little bit at the bottom of the canisters. It doesnt matter, the water enters the DI housing and flows to the bottom of the housing but it is forced through the Resin to get to the outlet which is in the top center of the housings lid. Water does not have to fill the housings. It probably wouldnt anyway unless there was a pressurized storage tank after the DI's or the cartridge was clogged up some.

Do you think that the chamber not filling with water will cause the resin cartridge to deplete faster than if the chamber was full? Or is the water getting pushed through the chamber enough to keep it at optimal conditions?

Thanx Again!

My DI housing never completely fills with water. It fills about 80%, but never goes much higher than that. I don't consider it a threat to the DI at all.

I doubt it, unless the air in the chamber has a higher than normal level of CO2. But I'm not sure what anyone could do about it short of finding a way to create some backpressure like adding a pressurized tank like those used for drinking water systems. I mean, there is no backpressure to cause the housing to fill up and the amount of flow from the RO isn't high enough flow to fill it up, its just a fast drip or slow stream.

I have a dual and it still never fills up. Only to maybe half if that.

Ok cool thanx again!
