Today we showed up for a complimentary water heater flush. The homeowner had one a free water heater flush and a spin at the grapevine mall. It is a Whirlpool water heater, was built in 06 and has had very little maintenance done to it. I had advised the homeowner that doing a water heater flush could cause a leak to happen from the tank, be homeowner still wanted to get the water heater flush done. Everything is working well, and there are no leaks when I left. Thank you for choosing comfort expert!
