No Hot Water in Benson? Water Heater Repair Starts With Finding What Failed
A shower that turns cold, a pool of water around the tank or a pilot that keeps going out all point to different faults, and some are a quick fix while others mean the tank has reached the end. Calls to our dispatch line go to one of our plumbers who serves Benson, and that plumber finds the cause before recommending anything.

No hot water: gas and electric units fail differently
The fuel type narrows the cause fast. A gas unit loses heat when the pilot or igniter fails, when the burner is dirty or when the gas supply stops. An electric unit loses heat when an element burns out, a thermostat fails or a breaker trips. Look at the label on the tank to see which you have, then use the table.
| Symptom | Gas water heater | Electric water heater |
|---|---|---|
| No hot water at all | Pilot out, igniter failed or gas supply off | Breaker tripped, high-limit reset tripped or both elements failed |
| Water is lukewarm | Dirty burner, weak flame or a thermostat set low | One of two elements failed or the thermostat is set low |
| Hot water runs out quickly | Sediment in the tank, a failed dip tube or a tank too small for the household | A failed upper or lower element, or sediment |
| Noise: popping or rumbling | Sediment baked onto the tank bottom | Sediment around the lower element |
| Water too hot | Thermostat or gas control valve fault | Thermostat fault; shut off power and call |
Gas units: pilot lights, igniters and burners
If the pilot light goes out repeatedly, the cause is usually a worn thermocouple, a dirty pilot assembly or a draft problem. A newer unit with an electronic igniter that clicks but never lights points to the igniter or the gas valve. A yellow, floppy burner flame instead of a steady blue one means the burner needs cleaning or the venting needs inspection. Soot around the tank base or a burning smell are stop-and-call signs.
Electric units: elements, thermostats and breakers
Check the breaker first. If it is on and there is still no heat, the high-limit reset button behind the upper panel may have tripped, which points to a failed thermostat or element. Electric work on the unit starts with power off at the breaker; testing parts with the power on is a task for the plumber or an electrician.
Leaking tank or leaking fitting?
A puddle under a water heater does not always mean the tank has failed. Water on the floor can come from a loose fitting, a temperature and pressure relief valve discharging, a leaking drain valve or condensation on a cold tank. Find the source before deciding on a repair.
A repair is possible when water comes from
- A supply or outlet connection at the top of the tank.
- The drain valve at the bottom.
- The temperature and pressure relief valve or its discharge pipe.
- An expansion tank or its fitting.
Replacement is the usual answer when
- Water seeps from the tank body or seams.
- The bottom is wet and the leak keeps returning after a fitting repair.
- Rust streaks run down the tank.
- The tank has failed a second time.
While you wait for service, close the cold water supply valve above the tank, turn off the power at the breaker or the gas control to the pilot setting, and open a hot tap to relieve pressure. How long a leaking tank can last before it fails further is unpredictable, since a small seep can become a full release without warning. For water you cannot trace, see tracing a leak to its source.
Flushing, sediment and what hardness has to do with it
Sediment settles on the bottom of a tank and insulates the water from the burner or the lower element. A flush drains the tank and carries some of it out. Ask the plumber what a flush will remove, since heavy sediment that has hardened may not flush out, and a stuck drain valve can leak after being opened.
How fast sediment forms depends on the water. City of Benson water comes from groundwater wells, and the 2025 water quality report does not list hardness, so there is no published figure to rely on. To find out, ask the Water System at 520-720-6336 or test the tap with a kit; for equipment choices, see a water test and softener options.

Repair or replace: how the decision gets made
Three questions settle most cases. How old is the unit? The serial number on the rating plate encodes the manufacture date, and the plumber can read it. Where is the leak or failure: a fitting or element is a repair, a tank leak is a replacement. How many times has it failed: a second major repair in a short time usually means replacement is the better use of money. For an old unit, a repair that restores heat today may not change the tank condition.
- Ask for the age of the unit, the cause of the failure and what the repair involves.
- Ask whether parts are available and whether the repair leaves other weak points, such as a corroded anode or fittings.
- Ask what a replacement would need, covered under replacing the tank, and whether a tankless unit is an option for your household.
Permits and codes
The City of Benson Building Department is at 120 W Sixth Street, phone (520) 720-6328, and its page lists the 2015 International Plumbing Code, 2015 International Residential Code and 2015 International Fuel Gas Code as adopted. We did not find a published rule on whether a water heater repair needs a permit, so ask the Building Department before work that changes piping, venting or fuel connections.

Questions about water heater problems
How long can a leaking water heater keep running?
There is no safe period. A small seep from a fitting may continue for a while, but a leak from the tank body can worsen without warning and release the tank contents. Close the cold supply valve, turn off power or gas and call a plumber.
Why is my water heater leaking from the tank?
Tank leaks come from corrosion that has worn through the steel, which a repair cannot fix. Water that appears at the top is often a loose fitting or the relief valve, and water at the bottom may be the drain valve. The plumber checks each before calling it a tank failure.
My water heater is not heating. What should I check first?
For a gas unit, check that the pilot is lit and the gas valve is on. For an electric unit, check the breaker and the reset button. If both look fine, an element, thermostat, igniter or control has probably failed, and a plumber can test it.
Water is leaking from my water heater. What do I do first?
Shut off the cold supply to the tank, cut the power or set the gas control to pilot, and open a hot tap to relieve pressure. Protect the floor and phone the dispatcher at (520) 340-7175.
How long do water heaters usually last?
There is no fixed lifespan. Use, water quality, sediment and maintenance all change it. The plumber reads the date on the rating plate, checks the tank and fittings and tells you whether repair or replacement makes sense.
Cold shower or a wet floor by the tank?
Close the supply valve on the cold pipe entering the heater if it is leaking, then call. The dispatcher books a plumber on our team who works around Benson.
