Work order
Water Heater Installation- New water heater unit: We supply Rheem, A.O. Smith, American Standard, or Navien depending on your fuel type and budget. The unit is sized to your household and matched to your existing gas line or circuit. You do not need to buy the tank yourself or coordinate delivery.
- Code-correct connections: We connect the gas or electrical supply, install new supply lines, and seal every threaded joint with Teflon tape or plumber's putty where required. Venting is checked against the Uniform Plumbing Code and International Plumbing Code before the unit fires up.
- Pressure and leak test: After the tank fills, we run a pressure gauge on the system and check every joint, valve, and fitting for weeping. We also test the temperature and pressure relief valve to confirm it opens and reseats. Nothing gets buttoned up until the system holds steady.
- Old tank haul-away: We drain the old unit, disconnect it, and carry it out of your home. It goes on our truck and gets disposed of properly. You do not need to drain it yourself, schedule a city pickup, or pay a separate disposal charge.
- Walkthrough and settings: We set the temperature, show you the anode rod and drain valve, and leave the manual with the tank. You get a call-back number for anything that looks off in the first week. Most customers are back to normal routines the same day.

How Our Water Heater Installation Process Works
Every install follows the same five steps, whether it is a straight swap in a Mill Hollow garage or a tankless conversion in a Hemming Village…
Tools and Methods We Use on Water Heater Installs
Each method answers a different question. Together they leave very little to guess.
Crimps the rings on PEX tubing when we run new supply lines. PEX is faster than copper in tight utility closets and handles Rexburg's cold-water temperature swings without stress cracking.
Threaded onto a hose bib or drain valve to confirm the system holds pressure after the tank fills. If the needle drops, we know a joint is weeping before we button anything up.
Used when a puddle under the tank could be the tank, a supply line, or a nearby slab leak. It isolates the source so you are not paying for a replacement you did not need.
Standard kit for cutting, fitting, and tightening on every install. Good tools mean fewer rounded nuts and less damage to old fittings that need to come apart.
When Rexburg Homeowners Call Us for Water Heater Installation
A 15-year-old tank in a Downtown Rexburg rental starts leaking on a Friday afternoon before a holiday weekend.

How Water Heater Installation Runs in Rexburg
Rexburg sits at about 4,800 feet, and the cold winters here are hard on water heaters. Incoming water in January can drop into the low 40s, which means your tank works harder to bring it up to temperature.
Downtown Rexburg
Older housing stock with utility closets that are tight on clearance. We measure before we order so the new tank fits the space and still meets code for venting.
Mill Hollow
Basements here are often finished, so we lay drop cloths and drain to a safe location to protect flooring during the swap.
Arcadia
Newer construction with PEX supply lines and modern venting. Installs here are usually straightforward tank-for-tank swaps.

PhotoLeaking 14-Year-Old Tank in Mill Hollow
Before: A 50-gallon gas tank in a finished Mill Hollow basement started weeping from the bottom on a Tuesday morning. The homeowner had a wet shop vac and a towel ring around the base, and the water was creeping toward stored boxes.
After: We shut off the supply, drained the tank, and installed a new 50-gallon Rheem the same day. The old unit was hauled out, the floor was dried, and the homeowner had hot water by 4 p.m. Total job time was about three hours.
Tankless Conversion in a Hemming Village Condo
Before: A condo owner wanted the utility closet back and was tired of running out of hot water when guests visited. The existing 40-gallon tank took up most of the closet, and the gas line was sized for the old unit only.
After: We upsized the gas line, ran new PVC venting through the exterior wall, and installed a Navien tankless unit. The closet gained about 6 square feet of storage.
Three Rental Units Replaced in the Campus Area
Before: A landlord near the BYU-Idaho campus had three 40-gallon tanks between 12 and 16 years old. One had already leaked once, and the other two were making popping sounds. All three needed replacement before the next lease cycle.
After: We replaced all three units over two days, pulled the permits, and coordinated access with the tenants. Each unit got a new shutoff valve and a drain pan. The landlord had one invoice and a record of each install for the property file.
Water Heater Problems We Solve for Rexburg Homeowners
Most water heater calls come down to one of a handful of failures.
Tank is leaking from the bottom
A leaking tank will not stop on its own. The water can rot flooring, soak drywall, and reach the gas valve or electrical connection.
No hot water or it runs out fast
A failed heating element, a bad thermocouple, or a tank full of sediment will leave you with cold showers.
Rusty or metallic-tasting hot water
Rust in the hot water usually means the tank lining has failed.
Popping or rumbling sounds from the tank
That noise is sediment boiling under the burner. It wastes gas, shortens the tank life, and gets louder as the buildup grows.
Water heater is too small for the house
A 40-gallon tank in a house with four people and a soaking tub will run cold every morning.
Why Rexburg Homeowners Replace Instead of Patch
A new water heater is not a glamorous purchase, but it is one of the few home upgrades you feel every single day.
Hot water that lasts
A correctly sized new unit keeps up with back-to-back showers, laundry, and dishwasher cycles.
Lower monthly gas bills
Modern Rheem and A.O. Smith tanks carry higher Energy Factor ratings than units built 12 to 15 years ago.
No more rusty water
Rust-colored hot water usually means the tank lining has failed. Once that starts, no flush or repair brings it back.
Haul-away included
We drain, disconnect, and carry the old tank out of your basement, garage, or utility closet.

Eleven Years of Plumbing Work in Madison County
We have been installing and replacing water heaters in Rexburg since 2015, which means we have worked on every era of housing stock in Madison County:…

Anode rod
We pull it and check how much of the rod is left. A worn rod means the tank is unprotected.
Flue draft
We test the draft at the hood. Weak draft means the venting needs correction before we fire the unit.
Supply pressure
We read the gauge at the drain valve. High pressure shortens tank life and points to a bad regulator.

What Rexburg Customers Say About Our Installs
Our 14-year-old tank started leaking on a Sunday night. I called Monday morning and they had a new 50-gallon Rheem in by 2 p.m. They drained the old one, hauled it out of the basement, and wiped down the floor. The price they quoted on the phone was the price on the invoice. No surprises.
I manage four rentals near campus and the water heaters are always the weak point. They swapped a failed unit in one of my units the same day I called, and they checked the venting on the other three while they were there. Found a bad flue on one and fixed it. That is the kind of thing that saves you a real problem later.
We went tankless with a Navien unit and I was worried about the gas line. They upsized it, ran the new venting through the wall, and had hot water running by the end of the day. They walked me through the temperature setting and the maintenance flush.
