Water Heater Repair in Spring Valley From a Local Plumber
If your water heater’s relief valve drips, your tank rumbles like a kettle, or your showers keep running cold, Sedco Plumbing can help — usually the same day. We repair and replace tank and tankless water heaters across Spring Valley, and we pay special attention to something many installers here skip entirely: water pressure.
Hillside Pressure Is the Silent Water Heater Killer
Gravity feeds Spring Valley’s hillside neighborhoods generously. On lots around Dictionary Hill and parts of Casa de Oro, street pressure can exceed 80 psi — beyond what plumbing code allows and well beyond what a water heater tank is built to endure day after day. Excess pressure stresses tank seams, forces temperature-and-pressure relief valves to weep, and shortens the life of every appliance connected to your water. We measure your pressure on every water heater call, and when it is high, we address it with a regulator and a properly charged expansion tank rather than just swapping the heater and waiting for history to repeat.
Straightforward Repairs and Code-Correct Replacements
Whether the fix is a thermocouple, an element, a gas control valve, or a full replacement, you get a flat-rate quote first. Spring Valley’s older housing stock means many heaters we replace were installed under earlier codes — so new installations bring the setup current: seismic strapping, drain pan and discharge routing, proper venting, and the expansion tank now required on closed systems. Your water comes from either Helix or Otay depending on where you live, and both deliver the hard water that makes periodic tank flushing worthwhile.
Thinking About Tankless?
A wall-hung tankless unit frees up garage or closet space and supplies endless hot water for busy households. We confirm your gas line and venting can support one before quoting, so there are no surprises mid-installation.

Water Heater Repair Questions
Why does my temperature-and-pressure relief valve keep dripping?
A weeping T&P valve usually signals excess pressure or thermal expansion, not a bad valve. Replacing the valve alone treats the symptom; testing your home’s pressure and adding a regulator or expansion tank treats the cause.
Do I need an expansion tank with a new water heater?
In most cases, yes. Homes with a pressure regulator or backflow device form a closed system, and California code requires thermal expansion control on them. It is inexpensive insurance for your new tank.
Can you replace a water heater in Spring Valley the same day?
Usually. We stock common sizes, and Spring Valley is minutes from our El Cajon base. Call before mid-morning and same-day replacement is typically achievable.
