About this service
Water Heater Installation Littleton CO: What the Job Really Involves
Water Heater Installation Littleton CO is a licensed plumbing service that removes your old tank or tankless unit, sets and connects a new one, and brings the whole system up to current code. The work covers draining and hauling off the old heater, checking the shutoff valve and gas or electrical supply, fitting a new T&P valve, expansion tank and dielectric unions, then pressure-testing every joint before we refill. A standard 40 or 50-gallon swap runs two to four hours. Tankless conversions take longer because we upsize the gas line and venting.
Most Littleton calls start the same way: a 12-year-old tank in a Columbine Hills basement finally rusts through, or a family of five in 80120 runs out of hot water by the second shower. Our water heater setup Littleton crews handle both. We test incoming water pressure with a gauge, check whether sediment buildup has already killed your lower heating element, and size the replacement to your actual usage instead of whatever the builder installed in 1998. If you're searching for water heater setup near me Littleton CO at 7 a.m. with no hot water, we answer.

What's included
What Our Water Heater Installation Includes
Every install we do covers the full scope: removal, new unit, connections, code-required safety parts, testing and cleanup. We do not nickel-and-dime on basics like a new T&P valve or haul-away. If something unusual comes up, like a corroded shutoff or a venting run that fails inspection, we tell you the added cost before we touch it.
✓
Old Unit Removal
We shut off the water and gas or power, drain the old tank with a hose, disconnect the lines, and haul the unit out of your basement or garage. No old heater left on your curb, no disposal fee tacked on at the end.
✓
New Unit and Connections
Your new tank or tankless unit gets set, leveled, and connected with copper pipe or PEX tubing, new dielectric unions to stop galvanic corrosion, and a fresh shutoff valve where the old one is worn.
✓
Safety and Code Parts
Every install gets a new T&P valve piped to within six inches of the floor, a drain pan with a line to a safe discharge point, and an expansion tank when your home pressure runs above 80 psi. These are not upsells, they are code.
✓
Permit and Inspection
When the scope requires it, we pull the permit through Arapahoe County and coordinate the inspection. You get the paperwork on file, which matters at resale and keeps your homeowner's insurance clean.
✓
Testing and Walkthrough
We fill, bleed the air, light the pilot or restore power, and set the thermostat to 120 degrees. Then we test hot water at two fixtures at once and show you the shutoff, drain valve and anode rod location before we pack up.
✓
Warranty Registration
We register your unit with the manufacturer, keep the serial number on file, and hand you the paperwork. Tank warranties run six to twelve years, and they only pay out if the install followed spec. Ours does.
How it works
How Our Installation Process Works
01
Phone Assessment
Call (720) 698-9814 and we ask the questions that matter: tank or tankless, gas or electric, age of the unit, how many people live in the house, and whether you have water on the floor right now. That five-minute conversation lets us bring the right size unit and the right parts on the first trip.
02
On-Site Evaluation
We check the shutoff valve, the gas line diameter or the circuit breaker amperage, the venting run, and the pan drain. A pressure gauge tells us if your home runs above 80 psi, which means you need an expansion tank. This takes about 20 minutes and it is where most cheap installs go wrong.
03
Upfront Pricing
You get one number before we start, covering the unit, the labor, the permit if required, and haul-away of the old heater. No hourly meter running while we work. If we find something unexpected, like a corroded shutoff valve, we tell you the added cost and you decide.
04
Removal and Install
We shut off the water and gas or power, drain the old tank with a hose, and cut it out. The new unit gets set, leveled, and connected with copper pipe or PEX tubing, new dielectric unions, a fresh T&P valve, and an expansion tank where pressure calls for it. Standard swaps take two to four hours.
05
Test and Walkthrough
We fill the tank, bleed the air, light the pilot or restore power, and set the thermostat to 120 degrees. A multimeter confirms the heating element is drawing correctly. Then we run hot water at two fixtures at once and show you the shutoff, the anode rod location, and the drain valve before we leave.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Pipe wrench and tube cutter
Used to break loose old fittings and cut copper or PEX cleanly so every new connection seats without cross-threading or burrs that cause leaks down the road.
Soldering torch
For copper sweat joints on the hot and cold lines. We use it where the existing plumbing is copper and the homeowner wants a permanent, code-approved connection.
Multimeter
Tests heating element resistance and thermostat continuity on electric units, and confirms the element is drawing correctly after install so we catch a bad part before we leave.
Pressure gauge
Reads incoming water pressure at the hose bib. Anything above 80 psi means you need an expansion tank, and skipping it is the number one reason new tanks fail early in Littleton.
Water heater element wrench
The correct-size socket for removing and torquing heating elements on electric tanks without rounding the hex or cracking the tank fitting.
Descaling pump
Circulates descaling solution through tankless heat exchangers at startup and during annual service. Colorado hard water scales condensing units fast without it.
Inspection camera
Lets us look inside venting runs and behind the unit to confirm the flue is clear and the pan drain actually goes somewhere before we set the new heater.
Real results
Before and after.
14-Year-Old Tank Swap in Columbine Hills
Before
A 40-gallon gas tank from 2011 was leaking from the base and leaving a puddle on the basement floor. The homeowner was mopping twice a day and had already lost a box of stored books to water damage.
After
We installed a 50-gallon Rheem unit with a new T&P valve, drain pan and expansion tank. Total job time was three hours. The basement floor was dry by evening and the household had hot water back before dinner.
Tank to Tankless Conversion in 80122
Before
A family of five kept running out of hot water by the third morning shower. Their old 50-gallon tank was working fine, but recovery could not keep up with the household's actual demand.
After
We installed a Navien condensing tankless unit, upsized the gas line from half-inch to three-quarter, and ran new PVC venting. Eight hours start to finish. First-hour capacity went from 78 gallons to unlimited.
Code Fix and New Install in 80128
Before
A pre-sale home inspection flagged the water heater for a missing drain pan, a T&P valve piped uphill, and no expansion tank on a 90 psi line. The seller needed it corrected before closing in two weeks.
After
We pulled the permit through Arapahoe County, installed a new code-compliant Bradford White unit with a proper pan drain and expansion tank, and passed inspection on the first visit. Closing stayed on schedule.
Problems we solve
Problems We Fix With a New Install
A failing water heater rarely dies quietly. It gives you warning signs for weeks first. Here is what we see most often in Littleton, and what happens if you wait.
Ask a pro →↗
No hot water and the pilot will not stay lit
We test the gas valve and thermocouple with a multimeter. If the tank is past ten years, replacement is the honest call. If it is newer, we repair it and save you the install cost.
Sediment buildup and popping sounds
On a tank past warranty, we replace it and flush the new one at install. On a newer unit, we drain and flush the tank, then set you up on an annual maintenance schedule so it does not come back.
Rusty or metallic-tasting hot water
We inspect the anode rod with an inspection camera. If the tank is still solid, a rod swap buys you years. If corrosion has reached the shell, we install a new unit before it fails on its own schedule.

Manufacturer TrainingRheem, A.O. Smith, Bradford White, Navien, Rinnai
Most standard tank replacements in Littleton run $1,200 to $2,400 in 2026, including the unit, labor, permit and haul-away. Tankless conversions typically land between $3,200 and $5,500 because they need a larger gas line and new venting. Electric swaps sit at the lower end, condensing gas units at the upper end. You get the exact number before we start.

Smith, Bradford White, Navien and Rinnai. We pull permits through Arapahoe County and stand behind the work. Call (720) 698-9814 and judge for yourself.
Yes. We take emergency calls around the clock for leaking tanks, no-hot-water situations and gas or electrical issues. If your tank is dumping water onto the basement floor at 2 a.m., call (720) 698-9814, shut off the cold inlet valve, and we will get a plumber moving toward your address in Littleton or Columbine Hills.
A standard 40 or 50-gallon tank swap takes two to four hours from arrival to hot water. Tankless conversions run five to eight hours because we upsize the gas line, run new venting, and commission the unit. We give you a time window when you book and call ahead before we arrive.
