WHAT'S INCLUDED IN WATER HEATER SERVICES
When a tank water heater starts leaking from the body, delivers rusty water or simply cannot keep up, replacement is usually the sensible fix. Active Plumbing installs gas and electric tank water heaters sized to your household's busiest hour, with the venting, drain pan and expansion tank the job calls for. You get a written price before work starts, and the old unit leaves with us.
A tankless water heater heats water as it flows through, so there is no stored tank to run out or leak. Getting one right in the Las Vegas Valley comes down to three things: sizing the unit to your fixtures, making sure the gas line and venting can support it, and planning for hard water scale. Active Plumbing checks all three before giving you a written price.
When a water heater runs cold, leaks or flashes an error code, the cause is usually one part rather than the whole unit. Active Plumbing diagnoses gas and electric tanks and tankless units, explains what failed and whether repair makes sense, and gives you a written price before any work starts. Trucks carry common repair parts, so many repairs finish in one visit.
A tankless water heater pushes water through a narrow heat exchanger, and valley water leaves scale behind every time it heats. Over time that scale restricts flow, triggers error codes and makes the unit work harder. Active Plumbing flushes the heat exchanger, cleans the inlet screen and checks the burner and venting so the unit keeps delivering steady hot water.
In a long single-story house, the hot water sitting in the pipe cools between uses, so every shower at the far end starts with cold water going down the drain. A recirculation pump keeps warm water moving toward those fixtures so it arrives sooner. Active Plumbing installs return-loop and crossover valve systems and sets them up with a control that matches how you actually use hot water.
Restaurants, salons, gyms, offices and apartment buildings each use hot water differently, so the right system starts with your actual demand. We size the equipment to your peak use, check gas supply, venting and electrical, and plan the changeover around your operating hours. You get a written price before work starts and we handle the permit.

Southern Nevada Water Authority reports the valley's water at about 280 parts per million, roughly 16 grains per gallon, which counts as very hard. That calcium and magnesium settles as scale on tank bottoms and heating elements and builds up inside the narrow heat exchanger of a tankless unit. A heater left unflushed works harder and fails earlier than its rated life, which is why maintenance matters more here than in many markets.
Active Plumbing handles the full range of water heater work. Water Heater Repair covers no hot water, leaks, pilot and burner faults, failed elements and thermostats, and relief valve problems. Tank Water Heater Installation replaces worn-out gas or electric tanks, and Tankless Water Heater Installation covers sizing, gas supply and venting for on-demand units. Tankless Maintenance & Descaling flushes scale out of heat exchangers. Recirculation Pump Installation brings hot water to distant fixtures sooner and cuts the water wasted waiting at the tap. Commercial Water Heater Installation serves restaurants, apartment buildings and other businesses with larger hot water loads.
Replacements are done to the local plumbing code, the Southern Nevada Amendments to the Uniform Plumbing Code, which cover items such as relief valve drain lines and drain pans where a leak would cause damage. Permits go through the building department for your address. Gas units run on Southwest Gas service, and we confirm the gas line can carry the load before installing a larger unit.
Our trucks carry common repair parts, so many repairs finish in one visit. Call (702) 438-3357, any hour, for water heater service.

The biggest difference is the water itself. The Southern Nevada Water Authority reports valley water at about 280 parts per million, roughly 16 grains per gallon, which is classed as very hard. Scale settles on tank bottoms and electric elements and builds up inside tankless heat exchangers, so a heater that is never flushed works harder and fails earlier than its rated life. Annual flushing or descaling, and a water softener where it suits the home, are practical ways to protect the equipment.
Location and code matter too. Many valley heaters sit in garages or exterior closets where summer heat stresses the unit and winter nights can still freeze exposed lines. Replacements follow the Southern Nevada Amendments to the Uniform Plumbing Code, including relief valve drain lines and drain pans where a leak would cause damage, with permits from the building department for your address. Gas units run on Southwest Gas service, so a larger or tankless unit may need the gas line checked before installation. Active Plumbing reviews your current setup and household demand and gives a written price before any work starts.
Real reviews from customers we've served for Water Heater Services.
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.

Typical Las Vegas Valley ranges are $150 to $500 for water heater repair, $800 to $1,500 for tank water heater installation, $1,500 to $3,500 for tankless water heater installation (with a pre-filter adding $150 to $300 where hard water calls for one), $150 to $250 for tankless maintenance and descaling, $400 to $900 for recirculation pump installation, and $1,500 to $6,000+ for commercial water heater installation. These are typical ranges, not a quote. Active Plumbing gives you a written price before work starts.
Active Plumbing is open 24/7 and technicians arrive in 30 to 60 minutes anywhere in the Las Vegas Valley. If the tank is leaking, shut the cold water valve on top of the heater and turn the unit off at its gas control or breaker. If you smell gas, leave the building, avoid switches and flames, and call Southwest Gas from outside before calling us at (702) 438-3357.
Water heater replacements generally require a permit and inspection. The permit comes from 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 such as Paradise, Spring Valley, Enterprise and Summerlin South. Active Plumbing confirms the requirement for your address and handles the permit on permitted work.
Yes. Active Plumbing holds Nevada State Contractors Board license #0047021, verifiable at nvcontractorsboard.com, and is insured. We are a fourth-generation family business serving the valley since 1991, with a 4.9 rating from more than 880 Google reviews. Warranties cover parts and labor, and customer financing is available.
Repair makes sense when a single part has failed, such as a thermostat, element, igniter or relief valve, and the tank itself is sound. A leaking tank cannot be repaired and needs replacement. Age, heavy scale and repeated repairs also point toward replacement. The technician explains both options, with a written price for each, so you can decide.
SNWA reports valley water at about 280 parts per million, roughly 16 grains per gallon. In a tank, that hardness settles as sediment that insulates the bottom from the burner and coats electric elements. In a tankless unit, scale narrows the heat exchanger passages. Regular flushing, descaling and, where it suits the home, a water softener help a heater reach its rated life.
Follow the manufacturer's schedule as a starting point, but with very hard valley water many owners descale at least once a year. Signs a unit is overdue include fluctuating temperature, reduced flow and scale error codes. Tankless Maintenance & Descaling circulates a descaling solution through the heat exchanger and cleans the inlet screen.
No. The federal Section 25C credit ended for equipment placed in service after December 31, 2025, so it does not apply to 2026 installations. NV Energy and manufacturers have offered rebates at times, so check the current program before you buy.
