Do RODI filter systems clog?

[Dom]

It used to take me 24 hours to fill a 40 gallon brute can.

Its been 3 days and it still isn't full. I turned it off. TDS coming out of the system starts at 3 and then drops to zero within 2 or 3 gallons. But it has been a long time since I replaced the media.

Could be your pre-filters (sediment stage) being clogged.

Yes, the sediment stage clogs and slows flow.

Considering I haven't changed any media in about 3 years, I think I'll just go ahead and replace them all.

Actually, I just looked at the tag with the date from the last time I changed
the media: 7/10/19.

So 5 years!
