Water Heater Repair and Replacement in Las Vegas
A tank water heater in Las Vegas typically lasts 8 to 12 years, shorter than the national range because water here runs about 17 grains per gallon and the resulting scale insulates the burner from the water it is meant to heat. Replacing one is a permitted job in all three valley jurisdictions.

What is included
The work itself
Water heater replacement
Old unit removed and disposed, new tank set, connected and tested, permit pulled and inspection scheduled.
Water heater repair
Thermostats, elements, gas control valves, thermocouples, T and P valves and expansion tanks.
Flush and scale service
Draining and flushing the tank to clear the sediment bed that hard water leaves behind.
Worth knowing
Before you book
The work is done by our own background-checked technicians, never day-labor subcontractors. Our license and insurance are on file with the Nevada State Contractors Board, and what a visit is actually like is in our customer reviews.
Gas and electric tank replacement
40, 50 and 75 gallon units, sized to the fixture count rather than to whatever was there before.
Thermal expansion control
Most valley homes sit on a closed system behind a pressure reducing valve, so an expansion tank is required and is checked on every replacement.
Permit and inspection handling
Clark County, the City of Las Vegas and North Las Vegas all require a permit for a replacement. We pull it and meet the inspector.
In your home
Find it before you need it
Knowing where the shut-off is, and what a failure looks like, is the difference between a wet floor and a flooded one. These walk through water heaters in a typical valley home.

Questions
Water Heaters, answered
How long does a water heater last in Las Vegas?
Plan on 8 to 12 years for a tank water heater here, the short end of the national range because of the water. At about 17 grains per gallon, valley water leaves a mineral bed on the tank floor that insulates the burner from the water it is heating, so the unit works harder for the same output. A softener and a tank flushed on schedule will usually reach the top of that range or beyond.
Should I repair or replace my water heater?
If the tank itself is sound and the fault is a thermostat, element, valve or thermocouple, it is a repair. Once the tank is leaking from the body, or it is past ten years and the repair is a large fraction of a replacement, replacing it is the honest call. We tell you which situation you are in before doing either.
Why does my water heater make a popping or rumbling noise?
That is the sediment bed. Valley water at roughly 17 grains per gallon drops mineral onto the tank floor, water gets trapped under it, and the popping is that water boiling through the scale. It is the audible version of the problem that shortens heaters here from the national twelve years to eight: the burner is heating a layer of rock instead of the water above it. A flush clears it if it is caught early enough.
What size water heater do I need?
Sized to the fixture count and how the household actually uses hot water, not to whatever was there before. Forty, fifty and seventy-five gallon units are the common valley sizes, and the previous owner's choice is not evidence of anything. We size it on the visit rather than replacing like for like out of habit.
Do I need an expansion tank with a new water heater?
In most valley homes, yes, and it is checked on every replacement. Houses here generally sit on a closed system behind a pressure reducing valve, which leaves heated water nowhere to expand into. Without an expansion tank that pressure works against the tank, the relief valve and every fixture in the house.
Are you licensed and insured?
Yes. Monkey Wrench Contractors LLC holds Nevada State Contractors Board license 0092999 and trades as Monkey Wrench Plumbing. We are a BBB accredited business with an A plus rating, and every technician is background checked. About thirty minutes before your appointment you get a text with the assigned technician's photo, name, license number and live ETA.
Do you charge for an estimate?
No. The inspection is free and you get a flat-rate price before any work begins, so the number you approve is the number you pay. If the scope changes once something is opened up, we stop and re-quote rather than adding to the invoice at the end.
