A water heater problem feels urgent because it is. A cold shower is an inconvenience, but a leaking tank can soak a garage floor or a closet in an hour. Our line is open 24/7 for water heater emergencies in Saratoga. If you see water around the tank, switch the heater to its off or pilot position, close the cold water shutoff valve above the tank and call us.
Most water heater calls start with one of three symptoms: no hot water, not enough hot water, or water where it should not be. Each has a short list of likely causes, and we work through them in order rather than recommending a new tank at the first look.
When a water heater problem is an emergency
Water around the base of the tank
A little condensation on a gas unit can be normal. A steady drip, a spreading puddle or rust streaks down the side usually mean the tank itself has failed, and that is a replacement, not a repair. Shut the water off at the heater and call.
You smell gas
Leave the house, do not touch light switches, and call 911 and your gas utility before you call us. Natural gas leaks are never a plumber-first call, and nothing on this page replaces that rule.
No hot water at all
Gas units may have a pilot or thermocouple issue. Electric units often need a heating element or a thermostat. Both are common repairs that can be finished in one visit when we carry the part.
Hot water that runs out too fast
A broken dip tube, a failed lower element or heavy sediment can cut capacity in half. These usually point to repair, unless the tank is already near the end of its life.
What to do before we arrive
These steps limit damage and give the technician a clear starting point.
- For a leak, turn the heater control to off or pilot and close the cold water shutoff on the pipe above the tank.
- Place a bucket or towels under any drip, and keep stored boxes off the floor around the heater.
- Do not drain or relight a unit you think has failed. Write down what you saw and any error code on the control.
- For a smell of gas, leave the building and call 911 first. PG&E asks customers to call 911 and then its gas emergency line at 1-800-743-5000.
Common repairs by water heater type
| Water heater type | Common failure | Usual repair |
|---|---|---|
| Gas tank | Pilot will not stay lit | Thermocouple or flame sensor replacement, burner cleaning. |
| Gas tank | Rumbling or popping noise | Sediment flush, sometimes a new anode rod. |
| Electric tank | No hot water | Heating element or thermostat replacement. |
| Electric tank | Breaker trips | Shorted element, wiring check. |
| Tankless | Error code or lukewarm output | Descaling, igniter or flow sensor service. See tankless water heater service. |
| Hybrid or heat pump | Slow recovery, error code | Filter, condensate drain and sensor checks. |
Repair or replace: how we decide
A good repair rule is to compare the cost of the fix with the age and condition of the tank. A new thermostat on a young tank is easy to justify. The same repair on a tank near the end of its warranty life is often money spent on a unit that will fail somewhere else.
If the tank is leaking from the shell, the decision is already made, and our water heater replacement service covers same-day swaps when units are in stock. If you are choosing a different type of heater, the water heater installation page explains what changes with tank, tankless and heat pump models.
Seismic bracing is a California requirement
California Health and Safety Code section 19211 requires new and replacement water heaters, and existing residential water heaters, to be braced, anchored or strapped against earthquake movement, at a minimum in line with the California Plumbing Code. If your heater stands loose in a garage or closet, ask us to check the straps during the repair visit.
Water heaters in Saratoga homes
Water in Saratoga comes from San Jose Water Company, and Valley Water News reports that most of the water San Jose Water delivers to Saratoga is treated water and groundwater. San Jose Water publishes hardness by source in its annual water quality report, and groundwater reads roughly three times harder than Valley Water imported surface supply. Harder water leaves more scale on heating elements and the tank floor, so a heater on a groundwater-fed street often needs flushing more often.
Many homes here, from foothill houses off Pierce Road to older cottages near Big Basin Way, put the heater in a garage or an exterior closet. A leak in those spaces can run for hours before anyone sees it, so a drain pan and a quick monthly look are cheap protection.
A sudden tank rupture that floods a room may be covered by homeowners insurance, while a slow leak from corrosion often is not. Check your policy and keep photos of the damage and the failed tank.

Common Questions
Yes. The line is answered 24/7, including weekends and holidays. If water is leaking, close the cold water valve above the heater and turn the heater to off or pilot before you call.
If the tank is leaking from the shell, replace it. If the problem is a part like a thermostat or thermocouple on a tank that is still in good shape, repair is usually the better value. We explain both options with prices before starting.
Sediment on the bottom of the tank traps water that boils and pops. Flushing the tank often fixes it. If the noise returns right away, the tank may be too scaled to recover.
Yes. Error codes, lukewarm water and a unit that shuts off mid-shower are usually scale, igniter or flow sensor problems. We service tankless units as well as standard tanks.
California Health and Safety Code section 19211 requires water heaters to be braced, anchored or strapped, at minimum per the California Plumbing Code. We can check your straps during the visit.
A pilot that will not stay lit is usually a worn thermocouple or a draft issue. It is a safety device doing its job. If you smell gas at any point, leave the house and call 911 first.
Tank units often last roughly 8 to 12 years depending on water quality and maintenance. Hardness, sediment and a worn anode rod shorten that. A yearly flush helps in areas where water is hard.
Yes. We service hybrid and heat pump units, including filter, condensate drain and sensor issues. Warranty terms vary by manufacturer, so keep your paperwork handy when you call.
