Someone please save me..

We had our powder room retiled and I’m concerned with how close they placed the tiles to the toilet flange. I already expected the toilet flange to be too low, due to the new tile, so I bought a toilet flange extender kit and a jumbo wax ring for the new toilet installation. After they completed the tile work I noticed they covered some of the flange (where the hardware is), with whatever toilet adhesive stuff they use, so now I fear I can’t get the existing flange out to add the extender. The flange is about 3/4” below the top of the tile. Someone please tell me I’m not screwed. Will my original plan work?

How to prevent well pressure switch from sticking?

Image is not mine, just for reference. At least twice a week, the little thing circled in green gets STUCK to the thing circled in orange. And I mean STUCK—tapping the cover with screwdriver doesn’t fix it. I instead shut off the breaker, and then manually knock green off of orange before restoring power. I only notice because it prevents the switch from engaging and I lose all my water pressure. No visible corrosion/damage to either of them. Switch is under a year old but has been doing this for two months. I live in hot & humid north Florida if that matters.
