Why Morrisville Even Cares About Your Water Heater

It’s not just bureaucracy for the sake of paperwork—Morrisville requires permits to make sure your installation:

• Complies with safety codes (no gas leaks or electric shorts, please!)
• Meets plumbing and electrical standards
• Protects you from high-pressure blowouts, scalding, and leaks

Even small changes like replacing an old heater with a new one of the same size? Still needs a permit.

Do I Really Need a Permit in Morrisville?

Short answer: Yes—if you’re replacing, upgrading, or installing a water heater, you need a Residential Plumbing Permit.

Here’s when you must apply:

• Upgrading from a tank to tankless system
• Changing from gas to electric (or vice versa)
• Moving your water heater to a new location
• Even a like-for-like swap requires permitting

⚠️ Skipping the permit could lead to fines, failed inspections, and issues when selling your home.

What About Electrical Work?

If you’re installing an electric water heater, and the job involves:

• Running new wires
• Installing a dedicated breaker
• Changing voltage

…you’ll also need an Electrical Permit. That means calling in a licensed electrician who knows Morrisville’s codes.

---

And What About Gas?

Gas water heaters are subject to even tighter scrutiny:

• You’ll need to pull a Mechanical Permit
• Installation must include a proper flue, gas shut-off valve, and CO detector
• You may also need a pressure test on gas lines

If your installer doesn’t handle this by the book? You could end up with a fire hazard or a failed home inspection.

Expansion Tanks: The Silent Rule Breaker

Morrisville follows the North Carolina Residential Code, which often requires thermal expansion tanks if you have a closed plumbing system (like one with a backflow preventer or pressure-reducing valve).

Not having one? Could result in burst pipes, leaky valves, and you guessed it—permit failure.

---

Who Can Do the Work?

Technically, you can pull the permit and do the work yourself—but Morrisville highly recommends (and prefers) a licensed plumber for anything more complex than tightening a faucet.

Hiring a pro ensures:

• Compliance with all local codes
• Faster inspections and approvals
• Less risk of injury or damage

---

Where to Apply for a Permit in Morrisville

You can apply through the Wake County Permit Portal, since Morrisville contracts inspections through Wake County. Here’s what you need:

• A registered account on the Wake County Permit Portal
• A project description (e.g., “40-gallon electric water heater replacement”)
• Contractor license details (if not DIY)

Permits typically cost between $60–$120, depending on the scope.

---

Inspections—Yes, You’ll Need One

Once installed, your water heater must be inspected by Wake County. That includes checking:

• Correct valve installation
• TPR (temperature-pressure relief) valve piping
• Bonding and grounding for electric heaters
• Expansion tank placement (if required)
• Venting and gas line integrity (for gas units)

If you fail inspection? You’ll need to fix and reschedule—so get it right the first time!
