Customer stated that they weren’t getting hot water. Found that water heaters are piped in series and the heater that is doing all the heating went out. Was able to relight water heater. Stood by water heater and water heater was heating for about 15 minutes without shutting off. Stated to customer that if water heater goes out again, let us know. Also gave customer price to pipe water heater heaters in parallel. Tested faucet in basement and it was getting hot water.
