KEY TAKEAWAYS
POPPINGSediment on the bottom of the tank. Flush it once a year — overdue tanks waste energy and wear out early.
HISSINGWater hitting the burner or a hot element. Check for a drip at the base — a leaking tank can't be repaired.
SCREECHINGA valve that's partly closed or failing. If it's the relief valve, don't cap or ignore it — call us.
TICKINGPipes expanding as they heat. Usually harmless; heat traps or pipe straps quiet it down.
