My parents are in town. My parents are professional plumbers in a way – they design piping systems for nuclear power plants, so they know all about stresses and damages on piping systems. My dad spent a good part of today looking at our own (non-radioactive) piping problem and going to Home Depot for supplies. It is still not fixed. Tomorrow – phase 2 of the repair involves my mother, the other piping professional (who was busy today playing Mah-johnn with her pals to deal with a leaky tub).
