Arrived to home to winterize outdoor shower. MyGuy used compressor to blow water out of shower. Disconnected unions, both shower heads and left everything open. Boiler drains in crawl are open and bleeder cap is on ledge inside crawlspace found in pics. No warranty on winterization. Customer has broken shower strainer. It was disconnected from shower pan due to dry rot. Left option to replace. Will apply a discount if we happen to come and fix it. Emptied trap as well. Also customer brought to my attention a gas smell from water heater. Did a bubble test but could not find leaks. His contractor is coming with a plumber to further diagnose. Did so as a courtesy. Customer did not want me to look any further into the issue because contractor is coming.
