The Biggest Problem With Buying a Home Is Simple: You Cannot See the Sewer Line
Written by Steven Shipler, Texas Licensed Master Plumber, Responsible Master Plumber (RMP), MBA, and host of The 4 Guys Education on YouTube.
The biggest problem with buying a home is simple. You cannot see everything you are buying. The roof, paint, flooring, cabinets, and fixtures are visible. The sewer line is not. That hidden pipe can become your problem the day after closing.
Buying a Home in Plano or North Dallas?
Schedule a sewer camera inspection before closing.

You cannot see everything you are buying.
You can walk the rooms.
You can look at the roof.
You can check the paint, flooring, cabinets, appliances, windows, doors, water heater, HVAC system, and visible plumbing fixtures.
That matters.
But the most expensive surprises are often the things you cannot see.
One of those hidden systems is the sewer line.
The sewer line may run under the yard, under landscaping, under a driveway, under the slab, toward the street, toward an alley, or toward a city sewer connection.
The toilets may flush during the showing.
The sinks may drain during the inspection.
The seller may say the plumbing works fine.
But none of that proves the underground sewer line is in good condition.
That is why The Sewer Inspection Company recommends a sewer camera inspection before closing, especially for homes in Plano, Allen, McKinney, Richardson, Frisco, North Dallas, Carrollton, Addison, Murphy, Parker, Fairview, Lucas, and nearby Collin County areas.
We also handle all plumbing emergencies 24/7.
The hidden system most buyers forget
Most homebuyers focus on what they can see.
That is normal.
Visible items feel easier to judge.
But a home is not just what is above the floor.
A home also includes the underground plumbing system.
The sewer line carries wastewater away from the home.
If that pipe has roots, standing water, a belly, a separation, a crack, a break, collapsed sections, deteriorated cast iron, or poor slope, the buyer may not know until after closing.
That is the wrong time to find out.
The sewer line may be hidden, but the repair bill will not be.
Why a standard home inspection may not be enough
A standard home inspection is important.
But it does not always include a sewer camera inspection.
Texas real estate inspection standards are minimum requirements for a real estate inspection.[1]
A home inspector may test fixtures, run water, flush toilets, look at visible plumbing, and report visible concerns.
That is helpful.
But running water through fixtures does not prove the buried sewer line is healthy.
A line can drain during a short inspection and still have serious defects.
That is why a sewer camera inspection is different.
It shows what is happening inside the pipe.
What a sewer camera inspection does
A sewer camera inspection uses a waterproof camera to inspect the inside of the sewer line.
The camera is usually run through a proper cleanout when available.
InterNACHI sewer scope standards describe sewer scope inspection as video-recording the main or exterior lateral sewer line from a proper cleanout or roof vent stack when access allows it.[2]
During a sewer camera inspection, the plumber looks for:
- Root intrusion
- Standing water
- Sewer bellies or low spots
- Offset joints
- Separated fittings
- Cracked pipe
- Broken pipe
- Collapsed sections
- Grease buildup
- Sludge buildup
- Cast iron deterioration
- Clay pipe separation
- PVC pipe settlement
- Poor slope or back-pitch
- Previous repairs that were never verified by camera
The camera does not fix the problem by itself.
It gives the buyer evidence.
That evidence can help the buyer decide whether the sewer line looks serviceable, questionable, or in need of cleaning, jetting, repair, replacement, or further testing.
The problem is timing
Before closing, a buyer still has leverage.
After closing, the repair usually belongs to the new homeowner.
If a sewer camera inspection finds a serious issue before closing, the buyer may be able to:
- Ask the seller to repair the problem
- Request a seller credit
- Renegotiate the purchase price
- Get sewer repair bids
- Ask for prior plumbing documentation
- Request more testing
- Decide whether the home is still worth buying
- Walk away if the contract allows it
After closing, that leverage may be gone.
That is why the best time to inspect the sewer line is during the option period or inspection period.
What buyers cannot see during a walkthrough
A walkthrough can tell you a lot.
But it cannot show everything.
During a normal showing, the buyer usually cannot see:
- The inside of the sewer line
- The condition of underground pipe joints
- Standing water inside the pipe
- Root intrusion below the yard
- Cast iron deterioration under the slab
- Clay pipe separation near the yard
- PVC pipe settlement
- Previous repairs hidden underground
- Pipe slope problems
- Broken pipe under landscaping
- Collapsed sections
- Grease and sludge buildup inside the line
That is the real risk.
The buyer is making a major financial decision while one of the most important systems is hidden underground.
The sewer line can look fine from the outside
A home can look clean and still have a sewer problem.
The yard can look perfect and still hide a broken pipe.
The toilets can flush and still have roots in the line.
The sinks can drain and still have standing water downstream.
The seller can be honest and still not know the condition of the sewer line.
Most sellers are not running a sewer camera every year.
They may only know that the drains worked while they lived there.
That is not the same as knowing the condition of the pipe.
Common hidden sewer problems in Plano and North Dallas homes
Plano and North Dallas homes can have different sewer risks depending on age, pipe material, soil conditions, trees, foundation movement, prior repairs, and construction history.
Common hidden sewer issues may include:
- Tree roots entering older pipe joints
- Clay pipe separation
- Cast iron pipe deterioration
- Standing water in low spots
- Sewer bellies caused by settlement
- Pipe separation after soil movement
- Pipe damage near the foundation
- Older repairs that were not properly documented
- PVC pipe that shifted or lost grade
- Grease buildup from kitchen use
- Under-slab drain line problems
- Pipe transitions from old material to new PVC
The only way to know what is happening inside the line is to inspect it with a sewer camera.
Questions buyers should ask before closing
Before buying a home, ask:
- Has the sewer line been camera-inspected?
- Can I see the sewer video?
- Where is the sewer cleanout?
- Was the camera run through the cleanout?
- Was any part of the line not accessible?
- What pipe material is the sewer line?
- Are there mature trees near the sewer path?
- Has the home had foundation work?
- Has the seller had recurring backups?
- Has the line been snaked or hydro jetted?
- Are there previous sewer repair invoices?
- Were permits or city inspections required for prior repairs?
- Is there standing water, roots, a belly, a break, or a separation?
- Was a repair area located?
If the answers are vague, slow down.
A major purchase should be based on evidence.
What if the home is newer?
Newer homes can still have sewer line problems.
Newer sewer lines may have:
- Poor slope
- Low spots
- Construction debris
- Separated fittings
- Improper installation
- Soil movement damage
- Damage from landscaping or utility work
- Problems near the city connection
Age matters, but age is not everything.
The better question is simple:
Do you want to know the condition of the sewer line before you own the home?
What if the home is older?
Older homes often deserve extra attention.
Older homes may have:
- Cast iron pipe
- Clay pipe
- Multiple pipe transitions
- Prior sewer repairs
- Mature trees
- Foundation movement history
- Older cleanouts
- Drain lines that have been cleaned repeatedly
An older sewer line can still drain while having defects that may become expensive later.
That is why older homes should be camera-scoped before closing.
What if the seller says the sewer line is fine?
The seller may be telling the truth based on what they know.
But most sellers do not know the full condition of the underground sewer line.
They may only know that the drains worked while they lived there.
A sewer camera inspection removes the guesswork.
It turns opinion into evidence.
What if the line was recently cleaned?
Recent drain cleaning does not replace a sewer camera inspection.
Drain cleaning may open the line, but it does not always explain why the line clogged.
The clog may have been caused by:
- Roots
- Grease
- A sewer belly
- A separated joint
- A broken pipe
- A collapsed section
- Heavy debris
- Poor slope
If the line was recently cleaned, that can actually be a reason to inspect it.
The camera can help show whether the cleaning solved the problem or only opened the line temporarily.
Sewer camera inspection vs. normal home inspection
| Inspection Type | What it checks | What it may miss |
|---|---|---|
| Standard home inspection | Visible and accessible systems and components | Hidden sewer line defects inside buried pipe |
| Sewer camera inspection | Inside of the accessible sewer line | Does not clean or repair the pipe by itself |
| Drain cleaning | Opens a blockage or restricted line | Does not prove the pipe is structurally sound |

For The Sewer Inspection Company, current pricing is:
- Standard sewer camera inspection: $189

How The Sewer Inspection Company helps buyers
Here is how we approach sewer camera inspections for homebuyers.
Step 1: Understand the purchase situation
We ask whether this is a home purchase, second opinion, recurring backup, prior foundation repair concern, mature tree concern, or seller disclosure issue.
Step 2: Find the best access point
The cleanout is usually the preferred access point. If there is no usable cleanout, another access point may be needed, and toilet removal may apply.
Step 3: Run the camera
We inspect the accessible portions of the sewer line and look for roots, standing water, bellies, separations, cracks, broken pipe, collapsed pipe, deterioration, and poor slope.
Step 4: Explain the findings
The customer should not need to be a plumber to understand the inspection. We explain what is normal, what is questionable, and what may need cleaning, repair, replacement, or further testing.
Step 5: Provide options
Sometimes the right answer is no repair. Sometimes it is monitoring, drain cleaning, hydro jetting, spot repair, sewer replacement, or further testing. The recommendation should match the evidence.
Why a Texas Licensed Master Plumber and RMP matters
A sewer camera is only a tool.
The real value comes from the person interpreting the video.
A Responsible Master Plumber is responsible for the general supervision and management of plumbing work performed under contracts secured under that license, including necessary permits, inspections, licensed or registered workers, and required supervision.[3]

FAQs
What is the biggest problem with buying a home?
The biggest problem is that you cannot see everything you are buying. The sewer line is underground, so hidden defects may not be obvious during a normal walkthrough or standard inspection.
Does a standard home inspection include a sewer camera inspection?
Usually, no. A standard home inspection may include visible and accessible plumbing items, but a sewer camera inspection is a separate inspection that shows the inside of the sewer line.
Why should I inspect the sewer line before closing?
Before closing, the buyer may still have options to negotiate, request repairs, request credits, get bids, or make a better purchase decision. After closing, the sewer repair may become the buyer’s responsibility.
What can a sewer camera inspection show?
A sewer camera inspection can show roots, standing water, bellies, offsets, separated fittings, broken pipe, collapsed pipe, cast iron deterioration, grease buildup, sludge, and other restrictions.
How much does a sewer camera inspection cost?
The Sewer Inspection Company currently charges $189 for a standard sewer camera inspection. If a toilet must be removed because there is no usable cleanout, a $50 add-on may apply.
