Water filter full?
« on: September 25, 2017, 01:25:27 PM »
Using those blue cylinder water filters on my city water line, I wonder how you know when the filter is "used up" and no longer working.

Have a look here at the variety of filters.  Most use the same process.
Under each type you will find particulars on how long they will last.  Usually it is three months or one camping season, but each person's experience (and use) may vary.

Technically, it is when it no longer does its' job.  If filtering to remove chlorine, when chlorine starts coming through (simple pool chlorine test), it is time to replace.  If filtering for particulates, when pressure through the filter goes down to an unacceptable level, it is time to replace.  Any chart you find will be based on AVERAGE contaminant level and AVERAGE usage and AVERAGE break through time.  Remember, they also sell filters!

In summary, there is no fixed answer.  Penny pinchers may go until they see a problem.  Others may change at or before published times.  Do what works best for you.

It's not a dumb question if you do not know the answer.

There is a fixed answer Gordon. I use a water quality meter to make sure my filters are still working properly.

No rocket science needed with those blue carbon filters. They get clogged up as they trap sediment and the water flow through them drops noticeably. If you physically lift the cartridge, you will note it is heavier as well (the weight of the crud it has trapped).

More sophisticated filters might be passing some of the things they are supposed to filter out, so water quality testing may be appropriate, but those blue cartridges are just carbon granules that filter out sand, sediment and some odors. Not much to go wrong as long as water continues to pass through it.

Tom, There is no fixed time or volume answer.  The meter, as I said, is the BEST method when possible for non sediment filters.

Nobody mentioned pressure drop.

Preacher said "when pressure through the filter goes down to an unacceptable level, it is time to replace".   :)) ;D ;)

Sorry, I missed that. :-[ I don't pay any attention to what he says anyway.  ;D
Preacher, I hope you realize I'm kidding. I've learned a good bit from you.
