Buying a new home is an exciting milestone, but it’s also one of the biggest investments you’ll ever make. While most buyers are quick to inspect the kitchen, layout, or roof condition, plumbing is often overlooked—and that can lead to costly surprises after the sale closes. A thorough plumbing inspection before making an offer can reveal hidden issues, protect your budget, and give you peace of mind.
Here’s a detailed plumbing checklist every homebuyer should follow, and how Green Group can help ensure you’re making a smart investment in your future home.
Check for Signs of Leaks and Water Damage
Before falling in love with a house, look carefully for signs of water damage. Even a minor leak can result in significant structural issues over time.
- Inspect under sinks for water stains, warped wood, or mold.
- Check ceilings and walls for bubbling paint, water spots, or soft drywall.
- Look for musty odors, which may indicate hidden leaks or mildew.
These symptoms may suggest past or active plumbing issues. If anything seems suspicious, have a professional plumber from Green Group investigate further to avoid inheriting a costly repair.
Test the Water Pressure in All Fixtures
Low water pressure can signal bigger plumbing concerns, including pipe corrosion, hidden leaks, or partially blocked lines. As you walk through the home:
- Turn on faucets in the kitchen and bathrooms to gauge pressure.
- Flush all toilets and test how quickly they refill.
- Run the shower to see if the pressure is consistent and sufficient.
Inconsistent or weak water flow across multiple fixtures may point to outdated or damaged plumbing. Green Group can evaluate water pressure concerns to determine if simple fixes or full upgrades are needed.
Inspect the Water Heater’s Age and Condition
Water heaters typically last between 8–12 years. Replacing one can cost hundreds to thousands of dollars, depending on the type.
- Locate the water heater and look for an installation sticker to find its age.
- Check for visible signs of rust, corrosion, or pooling water around the base.
- Listen for strange noises like popping or rumbling.
Don’t hesitate to ask the seller about recent maintenance. If the water heater is nearing the end of its lifespan, this could be a strong negotiation point. Green Group offers water heater inspections and can provide a realistic estimate for any replacement needs.
Ask About the Type and Age of Piping
The materials used in a home’s plumbing system can tell you a lot about its longevity and potential for future issues.
- Older homes may have galvanized steel pipes, which are prone to corrosion and can affect water quality.
- Polybutylene piping, used in homes from the late 1970s to mid-1990s, is known for unexpected failures.
- Look for copper, PEX, or CPVC piping, which are more durable and reliable materials.
If you’re unsure what type of plumbing the home has, ask the seller or home inspector. A plumbing expert from Green Group can confirm pipe materials and evaluate whether a repipe may be needed in the near future.
Examine the Main Shut-Off Valve and Outdoor Faucets
Being able to shut off the water quickly is essential in case of a leak or burst pipe. Make sure the main water shut-off valve:
- Is accessible (often located in the basement or near the water meter).
- Turns easily and isn’t rusted or stuck.
- Fully shuts off water flow when engaged.
Also, test any outdoor hose bibs for leaks or weak pressure, especially if the home is in a colder climate where pipes could have frozen in the past.
If you’re unable to locate or operate the main shut-off valve, have Green Group inspect the system and recommend necessary upgrades for safety and convenience.
Review Sewer Line Condition and Drain Performance
Sewer line issues can be some of the most expensive plumbing problems a homeowner can face. During your walkthrough:
- Run water in sinks and tubs to check for slow drainage.
- Listen for gurgling sounds when flushing toilets or draining tubs.
- Ask the seller about past sewer line repairs or backups.
For added protection, consider a video inspection of the sewer line, especially in older homes or properties with large trees nearby. Green Group can conduct sewer line camera inspections to identify blockages, breaks, or root intrusion before they become major expenses.
Evaluate the Sump Pump and Basement Plumbing
If the home has a basement, it’s essential to inspect any sump pump systems or plumbing running through this area. A failed sump pump can lead to flooding, mold growth, and water damage.
- Check the sump pump basin for standing water or debris.
- Ask the seller how often the pump cycles and if it’s been serviced recently.
- Inspect basement walls and floors for water intrusion signs.
If anything seems off or you’re unsure of what you’re seeing, contact Green Group for a professional basement plumbing evaluation.
Consider Water Filtration and Softening Systems
Some homes are equipped with water softeners or whole-house filtration systems. These improve water quality and protect appliances, but they also require maintenance.
- Ask if filters or softeners are included in the sale.
- Check the systems for rust, leaks, or overdue filter changes.
- Learn when the water treatment system was last serviced.
Green Group can inspect, maintain, or replace these systems to ensure you’re getting the best water quality possibleafter your purchase.
