7 Things Every Homebuyer Should Check Before Buying a House in Wisconsin (From a Plumber's Perspective)

Summer is one of the busiest times of the year for homebuyers in Wisconsin. Between open houses, inspections, financing, and moving plans, it's easy to focus on square footage, curb appeal, and updated kitchens.

But before you fall in love with a home, don't overlook one of the most important systems in the house: the plumbing.

As plumbers, we've seen homeowners move into their dream home only to discover expensive plumbing problems that could have been identified before closing. Here are seven things every Wisconsin homebuyer should check before signing on the dotted line.

1. How Old Is the Water Heater?

A water heater is one of the hardest-working appliances in your home, but it doesn't last forever.

Most traditional tank water heaters have a lifespan of 8-12 years. If the unit is approaching or exceeding that age, you may be looking at a replacement sooner rather than later.

Look for:

• Rust or corrosion

• Water stains around the base

• Leaks

• Unusual noises

• The manufacture date on the unit

Knowing the age and condition of the water heater can help you avoid unexpected expenses after move-in day.

2. Check the Home's Water Pressure

Low water pressure can be frustrating. Excessively high water pressure can be even worse, causing premature wear on pipes, fixtures, and appliances.

When touring a home:

• Turn on faucets

• Flush toilets

• Run multiple fixtures at once

• Check shower performance

Poor water pressure may indicate hidden plumbing issues, aging pipes, or problems with the home's pressure regulation system.

3. Inspect the Sewer Line

Many homebuyers don't think about the sewer line until something goes wrong—and sewer repairs can be among the most expensive plumbing issues a homeowner faces.

Older Wisconsin homes are especially susceptible to:

• Tree root intrusion

• Cracked pipes

• Offset joints

• Collapsed sewer lines

A sewer camera inspection before closing can provide valuable peace of mind and potentially save thousands of dollars in future repairs.

4. Find Out What Type of Pipes the Home Has

Not all plumbing systems are created equal.

Depending on the age of the home, you may encounter:

• Galvanized steel pipes

• Copper piping

• PEX piping

• Cast iron drain lines

Older galvanized pipes can restrict water flow and eventually require replacement. Understanding the plumbing materials used throughout the home can help you anticipate future maintenance and upgrades.

5. Test the Sump Pump

In Wisconsin, a functioning sump pump isn't just convenient—it's essential.

Heavy rains, snowmelt, and seasonal storms can quickly lead to basement flooding if a sump pump fails.

Check:

• The age of the pump

• Whether a battery backup system exists

• Signs of previous water intrusion

• General operating condition

A reliable sump pump can help protect your investment from costly water damage.

6. Evaluate Water Quality

Water quality varies significantly throughout Southeastern Wisconsin.

Some homes experience:

• Hard water

• Iron staining

• Sulfur odors

• Sediment issues

• Taste concerns

Ask if the home has:

• A water softener

• Water filtration equipment

• Previous water quality testing results

A simple water test can provide valuable insight into what treatment solutions may be needed after purchase.

7. Locate the Main Water Shut-Off Valve

This may sound simple, but many homeowners don't know where their main water shut-off valve is located until an emergency occurs.

Before buying a home:

• Locate the main shut-off valve

• Verify it operates properly

• Understand how to turn it off quickly

In the event of a burst pipe or major leak, knowing where this valve is located can prevent extensive water damage.
