Son John $ got up early to be ready for the plumber. When he turned on the shower, the connection to that hose burst! I never asked if he stood under the pipe coming out of the wall to get wet. The plumber called to say he was eleven minutes away, and we were ready to greet him. He remembered he had replaced the filter system the last time he came, and he commented on how very helpful David had been. John’s suspicion was correct. It was back pressure that blew up the line to the toilet, as well as the connection to the shower hose. The plumber was very impressed that John asked to video his comments on the filter when they went under the house. John assured him that his face would not be splashed all over the internet, something that had happened to John before. We now know to turn on the faucet near the entrance to the crawl space, and then to turn on every faucet in the house after changing the filter. John is going to put a note about it on the filter.

I heard John telling the story of the original explosion, and it was funny. He said he was facing the shower as he turned it on and is sure he had a funny expression on his face. “Why have I turned water on in front of me, but my back is getting wet?”
