Shut off the cold-water supply and power, then schedule service. A top leak usually points to the inlet/outlet fittings or the temperature and pressure (T&P) valve. We serve Las Vegas and Henderson. Sierra offers same-day service if booked by 6 PM and 24/7 emergency help. There are no service or dispatch fees. Ask about our Free Water Heater Repair Diagnostic.
- Turn the cold-water valve clockwise to off.
- Switch off the breaker or set gas control to off.
- Dry the top and check fittings and the T&P valve for drips.
