Tank water heater installation across the Las Vegas Valley. Gas or electric units sized to your peak demand, with drain pan, expansion tank and permit handled.
Customer financing available. Ask us about options.
A tank water heater stores heated water in an insulated tank and keeps it at temperature with a gas burner or electric elements. Installation means draining and disconnecting the old unit, setting the new one, and connecting water, gas or power, venting and the temperature and pressure relief line. Where a leak would cause damage, the local code calls for a drain pan, and a closed system needs a thermal expansion tank.
Las Vegas Valley water is very hard, about 280 parts per million, roughly 16 grains per gallon, according to SNWA. In a tank water heater, those minerals settle as sediment on the tank floor and coat electric elements. A tank that is rarely flushed works harder and tends to fail earlier than its rated life, which is why so many valley tanks are replaced after a leak at the base or a run of rusty water. Garage installations also deal with summer heat around the unit.
A good replacement starts with sizing. We look at your peak demand, like back-to-back showers with the dishwasher running, and the recovery rate of the unit, not just the number of bedrooms. We confirm the gas line, venting and relief valve drain suit the new tank, add a thermal expansion tank where the system is closed, and fit a drain pan with a proper drain where a leak could damage the home. Gas units connect to Southwest Gas service, and electric and heat pump models run on NV Energy power. The federal Section 25C credit for heat pump water heaters ended for equipment placed in service after December 31, 2025, though utility programs have offered rebates, so check the current program.
If you would rather move to on-demand hot water, see Tankless Water Heater Installation, and for a tank that may still be worth fixing, ask about Water Heater Repair. Call Active Plumbing at (702) 438-3357.

Sediment from hard water building up on the tank floor and making the burner or elements work harder. Corrosion once the anode rod is used up, leading to rusty water and leaks from the tank body. A relief valve that drips because there is no expansion tank or the incoming pressure is high. An undersized tank that runs out partway through the morning. Old venting or gas connections that need updating when the unit is replaced.
We check the existing tank, venting, gas or electrical supply, relief line and incoming water pressure.
We recommend a tank size and fuel type based on your peak demand, then give you a written price before work starts.
We remove the old tank, set the new one, and connect water, gas or power, venting, relief line, pan and expansion tank as required.
We leak test, fire the unit and confirm hot water, coordinate any inspection, and take the old heater with us.
Tank water heater installation typically runs $800 to $1,500 in the Las Vegas Valley. That is a typical range, not a quote. Tank size, gas or electric, venting changes, a new expansion tank or drain pan, and moving the unit all affect the figure. We can give a general idea on the phone and a written price on site before work starts. A straight swap of a similar unit is often finished in one visit, while changing fuel type or location takes longer.
We drain and disconnect the old tank, then set the new unit and connect water lines with shutoff valves, gas or electrical service, and venting suited to the model. The temperature and pressure relief valve drains through an approved material such as hard-drawn copper or CPVC to an approved location, never into the drain pan. Where a leak would cause damage, we install a pan at least 1-1/2 inches deep with a drain of at least 3/4 inch to a visible location, as the Southern Nevada Amendments to the Uniform Plumbing Code require. A thermal expansion tank is added on closed systems, incoming pressure is checked, and gas connections are leak tested. We install tank water heaters from Rheem, Bradford White and A.O. Smith.

Call Active Plumbing at (702) 438-3357 to replace your tank water heater. If the tank is actively leaking, shut off the cold water supply valve on top of the unit and, for an electric heater, switch off its breaker, then call. If you smell gas, leave the home, avoid switches and flames, and call Southwest Gas from outside before calling us.
Active Plumbing is based in the Las Vegas Valley, where technicians arrive in 30 to 60 minutes anywhere in the valley. For communities outside the valley, such as Primm, call us first to confirm we can schedule work at your location and what arrival time to expect, rather than assuming the same window applies.
The technical side of a tank replacement is much the same wherever you are in Southern Nevada. Very hard water settles as sediment on the tank floor and coats electric elements, so a tank that is rarely flushed works harder and tends to fail earlier than its rated life. A good replacement starts with sizing to peak demand and recovery, not just bedroom count. We confirm the gas line, venting and relief valve drain suit the new tank, add a thermal expansion tank on a closed system, and fit a drain pan where a leak could cause damage. Gas units connect to Southwest Gas service, and electric models run on NV Energy power.
Permits are decided by the jurisdiction for the specific address, so we confirm the building department before work begins. The federal Section 25C credit for heat pump water heaters ended for equipment placed in service after December 31, 2025.

When hot water heats up in a tank, it expands. In an open system that extra volume can push back toward the street supply, but where a pressure regulator, check valve or backflow device closes off that path, the pressure has nowhere to go. That is why a thermal expansion tank is added to closed systems when a tank water heater is installed. A relief valve that drips on an old heater is often a sign the expansion tank is missing or has failed.
Active Plumbing checks incoming water pressure and whether the system is closed on every tank installation, then adds an expansion tank where it is needed. The other code items get the same attention. Under the Southern Nevada Amendments to the Uniform Plumbing Code, the temperature and pressure relief valve drains through an approved material such as hard-drawn copper or CPVC to an approved location, never into the drain pan. Where a leak would cause damage, the heater sits in a pan at least 1-1/2 inches deep with a drain of at least 3/4 inch to a visible location.
These requirements come from the local plumbing code adopted by each jurisdiction, and the permit goes through the building department for your address. Tank water heater installation typically runs $800 to $1,500 in the Las Vegas Valley, a typical range rather than a quote, and an expansion tank or drain pan affects the figure. You get a written price before work starts. Call (702) 438-3357.
Real reviews from customers we've served for Tank Water Heater Installation.
The 40-gallon tank started weeping at the anode port. Same-day swap, seismic straps, and the old unit hauled off the pad. That call was from Lake Las Vegas. Hot water was back before the kids got home from school.

The ice machine at a clinic break room was on a garden-hose tap. A dedicated filtered line with a shutoff and a drain to an indirect receptor. That call was from The Section 10. Facilities passed the next infection-control walk.

The washer box sat too high and the standpipe siphoned. They dropped the box, reset the trap, and vented the arm. That call was from Sovana. Suds stay in the machine.

Tank water heater installation typically runs $800 to $1,500 in the Las Vegas Valley. That is a typical range, not a quote. Tank size, fuel type, venting and any code upgrades like a drain pan or expansion tank affect the figure, and Active Plumbing gives you a written price before work starts.
A failed element, thermostat, gas valve or anode rod on a younger tank is often worth repairing. A leak from the tank body itself cannot be repaired, and an older tank that has needed several repairs is usually better replaced. We will tell you which side of that line your unit is on.
Size it to your busiest hour, not just the number of people. Back-to-back showers, a bath and a dishwasher running together set the demand. Recovery rate matters too, because a tank that reheats well can outperform a larger one that does not.
Under the Southern Nevada Amendments, a drain pan is required where a leak would cause damage, such as in an attic or above a finished space. A thermal expansion tank is needed on a closed system. A dripping relief valve on an old heater is often a sign the expansion tank is missing or has failed.
SNWA reports valley water at about 280 parts per million, roughly 16 grains per gallon. Minerals settle as sediment on the tank floor and coat electric elements, so an unflushed tank works harder and tends to fail earlier than its rated life. Regular flushing and checking the anode rod help protect a new tank.
The federal Section 25C credit for heat pump water heaters ended for equipment placed in service after December 31, 2025, so it does not apply to a 2026 installation. Utilities and manufacturers have offered rebates, but those programs change, so check the current program before you buy.
Water heater replacements, especially gas units, usually need a permit. It goes through the building department for your address, which may be the City of Las Vegas, Henderson, North Las Vegas, Boulder City, or Clark County for unincorporated areas like Paradise or Spring Valley. We pull it and coordinate the inspection.
Ask for the license number and look it up at nvcontractorsboard.com, the Nevada State Contractors Board site. Active Plumbing holds license #0047021, has served the valley since 1991, and has a 4.9 Google rating with more than 880 reviews.
