The kind that work for the big companies, like Ryan homes. I deressurized the water system to move the lines and drain for the kitchen reno. When I repressurized it, a wild leak appears in the original work. All of 13 years old. A trip to home depot, a fix later, turn the water back on....and another leak. What. The. Holy. Crap. another trip, another fix, going outside while soaked in 15 degree weather, and not freezing due to the heat given off by my anger....

Also, i hit 60,000 in the R-Spec today. It hasn’t blown up.
