When people think “plumbing problems,” they usually think of leaks. But during a home inspection in Fort Wayne, Indiana, the most important plumbing issues I find are often the ones you can’t see. Because home inspections are non-invasive, I can’t open walls or dig up pipes — but there’s still a tremendous amount I can uncover through visual evaluation, functional testing, and experience.
In this part of our series, let’s look at the plumbing issues I commonly encounter and why a non-invasive plumbing inspection is still incredibly valuable for both buyers and sellers.
1. Active Leaks & Moisture Damage
While I can’t open walls, I can often detect active plumbing leaks at:
Under-sink areas
Supply lines
Drain traps
Water heaters
Toilet seals
Around tubs/showers
Gas meter
Gas appliance connections
Even small leaks can cause mold, rot, and long-term structural issues.
Why it matters: Minor drips today often become costly repairs tomorrow — especially if water has been leaking unnoticed in hidden areas.
2. Slow or Improper Drainage
By running sinks, tubs, and other fixtures, I can identify:
Slow drains
Gurgling or air in the system
Inconsistent flow
Fixtures that backup
These symptoms often indicate clogged lines, venting issues, or improperly installed drains.
Why it matters: Drainage problems rarely fix themselves — they typically get worse.
3. Water Pressure Problems
Using basic operating techniques, I check for:
Weak pressure
Surges
Uneven hot/cold balance
Water hammering noises
Low pressure can point to pipe restrictions or deteriorating supply lines. High pressure can damage appliances and fixtures.
Why it matters: Consistent water pressure is essential for safe and effective plumbing performance.
4. Aging or Problematic Piping Materials
Without opening walls, I can still identify visible piping types in basements, crawlspaces, and utility areas. Common issues include:
Galvanized steel (rust-prone, near end-of-life)
Polybutylene (known failure risk)
Corroded copper
Old cast-iron drains with exterior rust or scaling
Why it matters: Knowing pipe type helps buyers plan for future repairs or updates.
5. Water Heater Defects
Water heaters are one of the most high-risk, commonly neglected systems in a home. Issues I routinely find include:
Units past service life
Rusting or corrosion
Improper relief valve discharge lines
Missing expansion tanks (where required)
Inconsistent heating
Noisy operation
Why it matters: A failing water heater can leak, burst, or leave you with a very cold shower.
6. Inadequate Fixture Installation
Even in newer homes, it’s common to find:
Loose faucets
Improperly sealed tubs or showers
Drains not connected tightly
Leaking supply valves
Defective garbage disposals
These may seem small but can cause damage if left unaddressed.
Why it matters: “Small” plumbing defects can quickly turn into moisture damage and mold growth.
7. Toilet Issues
Toilets are one of the most frequently overlooked fixtures. I often find:
Loose toilets
Failing wax rings
Constant running
Improper flushing
Leaks at the base
Why it matters: A leaking toilet flange can cause hidden subfloor rot — one of the most expensive repairs in a bathroom.
8. Venting & Trap Issues
While I can’t see inside the walls, I can identify symptoms of improper venting, such as:
Gurgling noises
Slow drainage
Odors
Siphoned traps
Leaks from the drain, waste, vent (DWV) system
These often trace back to incorrect venting or DIY modifications.
Why it matters: Poor venting affects every fixture downstream.
Why a Non-Invasive Plumbing Inspection Is Worth It
Even without opening walls or cutting into pipes, a home inspection can reveal significant plumbing concerns. Many of the most serious plumbing issues show early warning signs during normal operation — you just need someone trained to recognize them.
A non-invasive plumbing inspection helps:
Catch leaks before they cause hidden damage
Identify outdated or high-risk piping materials
Reveal drainage and venting problems
Prevent water heater failures
Provide buyers and sellers with realistic expectations

Final Thoughts
