No hot water, a tank that pops and rumbles every time it fires, or water pooling at the base: each of those has a specific cause, and finding it comes before any recommendation. Number One's licensed plumbers have been repairing and replacing water heaters across the Albuquerque metro since 2005, and many of the "dead" water heaters we're called to need a part, not a new tank. We diagnose first, explain what we found in plain language, and let you decide from there. Weekend calls are billed at weekday rates; after-hours calls carry an additional charge.
No hot water is a symptom, not a diagnosis, and the causes range from a part we carry on the truck to a tank that has reached the end of its life, or, on a tankless unit, mineral scale that a descaling often clears. Telling the difference is the first job. On a gas water heater, our plumbers work through the ignition sequence in order: pilot or igniter, thermocouple or flame sensor, gas control valve, and venting. On an electric unit, we test the upper and lower heating elements, their thermostats, and the high-limit switch, which trips when something upstream has gone wrong.
Some failures show up on both types. A broken dip tube lets incoming cold water mix at the top of the tank, so hot water turns lukewarm within minutes. A worn temperature and pressure relief valve drips or discharges. A thick layer of sediment insulates the burner or lower element from the water it is supposed to heat, and on Albuquerque water that layer builds faster than most homeowners expect.
Tankless units have their own failure points, and the most common one here is mineral scale on the heat exchanger, which cuts flow and triggers error codes. Across all types, most repairs are measured in parts and labor, not replacements, and we carry common components on the truck so a single visit usually resolves the problem.
Replace the water heater when the tank itself has failed, because a leaking tank cannot be repaired. Short of a leak, the factors that matter are the age of the unit, the cost of the repair relative to a new heater, how often it has needed service recently, and whether the failed part is a wear item or the tank. A tank water heater typically lasts eight to twelve years and a tankless water heater fifteen to twenty. If you don't know how old yours is, the manufacture date is printed on the label on the side of the unit.
Rusty hot water, water seeping from the tank, rumbling that comes back after a flush, hot water that no longer keeps up with the household, and energy bills that climb with no change in use all point to a tank near the end of its life. A failed element or thermocouple on the same tank is a different conversation, and on a heater in its first eight years or so it is almost always worth fixing. What we will not do is turn a repair call into a replacement pitch. If your water heater has years left, we will tell you so and fix what is broken.
When replacement is the answer, fuel and size come first. Gas tanks recover faster and usually cost less to run, which suits larger households, but they need proper venting; electric tanks need no venting but reheat more slowly. A family of four is usually well served by a 50-gallon tank, and tankless water heaters are worth a look if you want endless hot water and a longer service life. Replacement is permitted work, and we handle all of it: we pull the permit, remove and haul away the old unit, and install the new one to code, including venting, gas or electrical connections, and the relief valve, with most standard tank replacements finished in one visit.
Albuquerque's hard water is the main reason water heaters here fail early. It carries high levels of calcium and magnesium, and heating that water drives the minerals out as sediment that hardens on the bottom of the tank. When the burner fires, water trapped under that layer flashes to steam, which causes the popping and rumbling homeowners describe. The sediment also makes the unit run longer for the same hot water, so your gas or electric bill climbs with no change in how you use it.
Every tank has a sacrificial anode rod that corrodes so the steel tank doesn't. Hard water uses that rod up faster, and once it is gone, the tank is the next thing to corrode, first as rusty hot water and eventually as a leak. Checking the anode rod and replacing it when it is spent is one of the simplest ways to protect a tank that is otherwise sound. Cloudy or sandy hot water is a different signal: that is usually sediment rather than rust, and a flush often clears it.
The gap between a tank that lasts eight years and one that lasts twelve is mostly maintenance. Flushing a tank once a year keeps sediment from hardening, and tankless units need annual descaling to keep scale off the heat exchanger. If a tank has gone years without a flush, have a plumber handle the first one, because heavy sediment can clog the drain valve. For more on what minerals do to the rest of your system, see our guide to Albuquerque hard water and your plumbing.
We repair and replace all major residential water heater brands, including Rheem, A. O. Smith, and Navien.
Most of the water heater failures we respond to were building for a year or more before they happened, usually as sediment that hardened on the bottom of the tank. The Uno Care Club puts water heater flushing on a schedule, along with seasonal service on your heating and cooling equipment, priority scheduling when something does go wrong, and repair protection that takes the sting out of an unexpected call. Members go to the front of the line when a water heater fails on a cold morning, which is when it matters most.
Members earn up to $600 annually and can bank up to $3,000 in credits.
Real people, real results
"Thank you Number 1 plumbing! Chance came out to replace the flame sensor on our tankless water heater and the job was complete in under an hour. He was friendly, explained everything and showed up within the promised window."
"Carlos and his associate did a great job installing a new water heater which included widening a roof vent and running an overflow pipe to the outside. We're very happy with the quality and timeliness of the job."
"Cory is an artist! He installed a new tankless water heater in a limited space where our old 18 year old unit was located. He did what others said was impossible. And he handled all the new codes with competence and confidence."
Number One answers the phone around the clock, every day of the year. If your tank is leaking, shut off the cold supply valve above the heater and turn off the gas or the breaker, then call us and we will get a plumber to you as quickly as the schedule allows. Weekend calls are billed at weekday rates; after-hours calls carry an additional charge. Every repair is backed by our Satisfaction Pledge.
Sediment. Minerals from Albuquerque's hard water settle on the bottom of the tank, and water trapped beneath that layer boils when the burner fires. Flushing can clear it if it's caught early, but sediment that has hardened into a crust often won't flush out, and by then the tank has been running hot at the bottom for a while.
The usual causes are sediment taking up space in the tank, a failed lower heating element on an electric unit, or a broken dip tube that lets cold water mix in at the top. All three can be diagnosed in one visit, and the element and dip tube are straightforward repairs.
First, check whether the rust appears only in the hot water. If it does, the source is the water heater, and it's either a depleted anode rod, which is a repair, or a corroding tank, which is not. If the cold water is discolored too, the problem is more likely in your pipes. Cloudy or sandy hot water is a different issue: that's usually sediment, and a flush often clears it.
It depends on where the water is coming from. A drip at a fitting or from the relief valve discharge line can often be repaired. Water coming from the tank itself means the tank has failed, and it can go from a slow leak to a flooded room with little warning. Shut off the cold supply valve above the heater and turn off the gas or the breaker, then call us.
A tank water heater typically lasts eight to twelve years, and a tankless unit fifteen to twenty with annual descaling. Albuquerque's hard water pushes units toward the low end of those ranges when they aren't maintained.
