My wife came home with one of those $10 chlorination gadgets for the toilet that 'self-cleans' the bowl after flushing. Installation seemed simple enough, but within minutes I had broken the fill valve assembly at the base. I quickly turned off the water supply at the wall and tried to loosen the coupling nut that secures the valve so I could replace the part. It was corroded and wouldn't budge. I decided to pull the toilet for better access to the stuck nut. I removed the flange nuts and lifted the toilet with all my might...and learned that the caulking bead around the toilet base can be exceptionally strong. The bowl base broke into three pieces and water spilled everywhere. My wife and I decided that I should quit while I was behind and call a real plumber. The $350 bill was an expensive end to a simple task, but there is no cleaner toilet than a brand new one.
Last year my fiancé and I started our first home improvement project together, aptly, a shower. We installed a new control valve along with new tile. Although my fiancé was still grouting the tile, I decided it was safe to turn on the main water supply valve because we'd finished the plumbing. A second later, a scream echoed through the house. I ran to the bathroom and saw that the shower was blasting on my fiancé. We'd left the valve in the open position and she couldn't turn it off because we hadn't installed the handles. Anyway, a year after this first shower, we're happily married!
My brother-in-law and I decided to help his father remodel his bathroom. Being pretty handy, we thought it would be a snap. When it came time to set the tub, we hooked up the water supply and the PVC waste lines, then took a break for dinner to let the glue dry. When we finished eating, we turned on the water to try it out. After a few seconds, my brother-in-law said he could hear water dripping. Then it turned into a gusher. After investigating the problem, we found we'd used rubber cement instead of PVC glue. The containers were similar and were right next to each other on the shelf. After a couple of hours of redoing our mistake, we were ready for a hot shower!
