A quick online search makes water heater replacement look simple enough to handle yourself. In reality, it involves gas or electrical connections, venting, water pressure, and local permit requirements — and getting any one of them wrong can mean a safety hazard, a voided warranty, or a failed inspection.
Here’s what water heater replacement in Aurora, CO actually involves, and why most homeowners leave it to a licensed plumber.
Quick Answer
Water heater replacement should be handled by a licensed plumber. It involves gas or electrical connections, proper venting, and — in most areas, including Aurora — a permit and inspection. DIY replacement can void your warranty, create safety risks, and cause issues if you later sell your home.

What Water Heater Replacement Actually Involves
Replacing a water heater is more than swapping one tank for another. A proper installation includes:
- Safely disconnecting and draining the old unit
- Reconnecting gas, electrical, or venting lines to code
- Setting the temperature and pressure relief valve correctly
- Sizing the new unit appropriately for your household’s hot water needs
- Testing for leaks and proper operation before the job is considered done
Why DIY Replacement Is Risky
Gas water heaters involve a live gas line — a poor connection can lead to a leak or, in rare cases, a fire hazard. Electric units carry their own risk if wiring isn’t handled correctly. Beyond safety, DIY installation can also:
- Void the manufacturer’s warranty, which often requires professional installation
- Fail a home inspection if you sell your house later and the work wasn’t permitted
- Cause water damage from an improperly sealed connection
- Create code violations that need to be corrected — sometimes at greater cost than hiring a professional from the start
Skip the risk — let a licensed plumber handle it right the first time.
Permits and Code Requirements in Aurora
Most water heater replacements require a permit and inspection under local plumbing code — this isn’t unique to Aurora, but it’s often overlooked by homeowners attempting a DIY swap. A licensed plumber typically handles the permit process as part of the job, ensuring the work is documented and code-compliant. Skipping this step can create problems later, especially if the issue comes up during a home sale or insurance claim.
Who Should Replace Your Water Heater
A licensed, insured plumber is the safest and most reliable choice for water heater replacement in Aurora. Look for a company that:
- Is licensed and insured in Colorado
- Pulls the required permit and schedules inspection
- Provides an upfront, written estimate before starting
- Offers both tank and tankless replacement options

Can I replace my own water heater?
Technically, you can attempt it, but it’s not recommended. Gas and electrical connections, venting, and permit requirements make this a job best left to a licensed professional.
Is it legal to replace your own water heater?
In many areas, homeowners are legally allowed to do their own plumbing work, but a permit and inspection are usually still required. Skipping that step can create legal and safety issues later.

Cost depends on unit size, tank vs. tankless, and whether new venting or lines are needed. Grig Plumbing provides a free estimate before any work begins.
