DI System- Observed Delay in DI Water Production Cycle

[ppednekar25]

The DI System has been having issues with producing the water very slowly. In the past couple of cycles, it has been filling only about 50-60 gal/cycle that we usually run overnight.

So far, we have cleaned and changed all the filters in the system and have been doing that periodically as required. We change the sediment filter every 100 gal, DI Resin Filter once the resin looks used up and turns dark brown and changing the carbon filter every month.

I additionally also checked the RO Membranes and they look fine and quite good.

Observations/Comments:

1. The maximum pressure of the input water is within range: 50-60 psi when the valve is turned all the way on.
2. While discussing with Zoe, she suspects that our canisters might be old and some of them have slight mold according to her which might need a change.
3. The TDS meter also shows readings within range as expected.
