Buying a Home in Billings or Laurel? What to Ask About the Plumbing

House hunting in Billings or Laurel is exciting—whether it’s your first home or your forever one. But beyond curb appeal, updated kitchens, or hardwood floors, there’s something less glamorous but just as important to inspect: the plumbing. What lies behind the walls and under the floors can have a huge impact on your comfort, safety, and future repair bills.

At Brown Plumbing & Heating, we’ve helped many new homeowners avoid hidden headaches by identifying plumbing red flags before closing. If you’re shopping for a home in Yellowstone County, here’s what to ask, inspect, and understand before signing on the dotted line.

1. How Old Are the Pipes—and What Material Are They Made Of?

Many homes in Billings and Laurel were built decades ago, meaning their plumbing systems might still rely on outdated materials like galvanized steel or cast iron. These pipes corrode over time, leading to reduced water pressure, rusty water, or leaks.

Ask the seller or inspector:

What type of plumbing material does the home have?

When was it last updated?
If the answer is unknown—or it hasn’t been touched since the ’70s—you may want a professional plumber to assess the risk and estimate replacement costs.

2. What’s the Water Pressure Like?

Water pressure that’s too low or too high can be a sign of plumbing issues. Low pressure may stem from mineral buildup in old pipes, while high pressure can strain fixtures and lead to leaks.

During a showing, turn on multiple faucets and test the shower. If the pressure fluctuates or is noticeably weak, you’ll want it checked. We can perform a pressure test and inspect the system for any hidden issues.

3. Has the Sewer Line Been Inspected?

Tree roots, clogs, or collapsed pipes in the main sewer line can cause expensive backups—and they’re not something you can see with a flashlight. In older homes especially, it’s smart to request a sewer camera inspection.

This quick check can save you thousands by identifying blockages or cracks before you commit.

4. What’s the Condition and Size of the Water Heater?

Ask how old the water heater is and whether it’s large enough for your household’s needs. A standard tank lasts about 8–12 years, and replacing one that’s on its last legs is a cost you’ll want to factor in.

Also, check for signs of rust or leaks around the tank. And if you plan to install a large tub or upgrade to high-efficiency appliances, make sure the heater can keep up.

5. Are Shut-Off Valves Accessible and Functional?

Every sink and toilet should have an accessible shut-off valve—and the home should have a clearly labeled main shut-off. This matters in case of emergencies or repairs.

If valves are hard to reach, corroded, or missing entirely, that’s something you’ll want to address early.

6. Are There Signs of Water Damage or Mold?

Discolored walls, warped flooring, or a musty smell might point to past or ongoing leaks. These can be especially common around bathrooms, kitchens, and basements.

A professional inspection can help determine if plumbing is to blame—and whether it’s been repaired properly or just patched up.

7. Does the Plumbing Meet Current Code?

Building codes evolve over time. If the home has undergone DIY renovations, the plumbing might not be up to today’s standards. That can lead to problems with insurance claims, future remodels, or city inspections.

Hiring a licensed plumber to evaluate the system ensures peace of mind before moving in.
