Return to install new water heater. Removed old unit, cleaned behind and under. Due to space constraints and restrictions we were unable to place a drip pan. The alterations needed to make it fit would render the drip pan useless. New ball valve installed, thermal expansion tank and mounting bracket installed. New gas sediment trap installed. Unit pressurized and lit. I set one mark below standard at Ms. Pat’s request. Cleaned site and made sure everything was working. I discussed the benefits of our maintenance membership program, and ensured Ms. Pat is happy with all work today. Water to building did not have to be shut down today.
