The filter finally got clogged totally. Only a trickle was getting through. There's a spinny thing in the water intake that catches straw that I cleaned out, and I *think* I flushed the filter into a compost bucket correctly. My particular filter is one of 3 models in the instruction book. It only goes into detail on how to flush the models with the squeeze cranks. Mine doesn't have a crank. Water is getting through and looks clear so I think I did it. It should go back to good clarity overnight. It's been 12 days since I set it up, so I probably need to do a basic flush and maintenance every week or 10 days.
Good news is that the tile guy was consistent. The bad news is that he was consistently bad. Had the valves too far out in BOTH bathrooms. So I had to cut the tile away tonight as the plumber is coming tomorrow to move them back. Tile dude will come out later and retile everything. BTW, leaving for work at 6:45am and getting home at 9:15pm really sucks. Too old for days like that anymore.
