Performed hsp maintenance. House had two full baths upstairs and one downstairs powder room. Plumbing in all bathrooms looked in great condition, except for the tub faucet handles were loose. The original set screws were misplaced and both handles had different ones.customer will get new ones from kohler down the road. House had 50 gallon natural gas water heater that was installed back in 2012. Drained the heater with no problem and looked at the anode rod and saw that it had been attacked with lime scale. Switched it out with an aluminum rod to prolong the life of the heater. House pressure was 65psi
