Plumbing: Water pressure was fine, all of a sudden all faucets in house have gone to slow trickle, hot and cold water. Is there a clog in the system?
Plumbing: My water heater is in the basement. It takes quite a while for hot water to reach the second floor bathroom sink. If I run hot water on the ground floor for a minute,  will that hasten the delivery of hot water to the second floor?
