07APR24 - Spent most of the day replacing the filter cartridges in the water treatment system yesterday and I was overdue by three months..DAMMIT! it's been on "the list" for some time but some other chores got higher priority until yesterday.

For a number of years, I replaced these two every six months but two years ago, I decided to push it to a year based on things I'd read and, because the carts weren't super contaminated at the six month mark.

That was a mistake. Here you see the two previous carts next to their new replacements and obviously, it was time! Normally I use a paper, pleated cart on the pre-filter side (sediment from the City water supply,) but I ran out and last year, used a carbon filter cart instead as that was all I had.

Worse, I forgot to order MORE like a dumbshit so I had to use another carbon cart this time but, I did order a half dozen of the correct filters and when they arrive, I'll pull out the carbon and put in a pleated. The carbon got most of the sediment but, since it's not pleated and only has a fine mesh outer layer, the surface area is probably ten times less. Looking at the condition of the polypropylene "braided rope" final filter, it's obvious that a bunch of sediment got through the pre-filter.

Definitely going back to six month intervals.
