For almost 2 years we have only had a trickle of hot water into our large tub in the basement. Dad has tried to fix it several times with no luck. So when we have wanted a bath we start the tub and set the timer for 30 minutes and that's when it would be full. Yesterday after fixing a pipe going into the water heater that broke (ruining a wall or two) he and Tyler decided to try again. SUCCESS!! The built up pressure shot this thing out at Dad. Mysteriously it was in the pipe. You can see how little water was getting around it. It's not a pipe connected to a drain so we can't have dropped it in there. It's so weird, but will remain a mystery. On the plus side last night the bathtub filled up in about 5 minutes.
