Customer called in about wanting us to take a look at his water heater. It’s not wanting to light. Upon arrival customer has two 50 gallon water heaters ran in series. Secondary water heater is the one with issues. Was able to relit water heater. Water heaters are 13 years old. After discussing different options, customer would like to proceed with installing tankless water heater and also relocating sprinkler system to make room as well.
