House had flooded about half a foot prior to arrival. Customer replaced his sump pump this morning. On arrival I noticed that the water heater pilot light on a 19 year old water heater had gone out. Tried to relight for awhile and couldn’t get it to turn over. The igniter wasn’t firing every time it was pushed and it looked like there was water damage inside the burner area. Customer also didn’t have an expansion tank for this water heater and the temperature and pressure valve was dripping. Left estimates to replace heater.
