Hot water heater service. The customer could not get the water heater lit after the water softener hose came loose and put the heater out. The customer had already cleared water out of the bottom of the heater, and it fired up instantly on the first try. The heater is only a couple of years old best option is to start by just lighting the heater and see if any issues arise in the future. I took a picture of an EPA notice from the city of Crest Hill, and the customer would like to know if we install any whole-house water filter systems that can help with what is listed by the EPA.
