The seller says the sewer line was replaced. What paperwork proves it?

Ask for the plumber's itemized invoice, the City of Mobile plumbing permit and the city inspection approval sticker. Those are the documents MAWSS itself asks for when an owner reports a full lateral replacement. Then scope it anyway: the video confirms the new pipe runs the whole way and that the connection at the property line is sound.

The house has been empty for years. Is a scope still worth booking?

More so, because of the MAWSS capping rule for vacant houses noted above. Ask MAWSS about the account status before closing, and have the line filmed so you know what you'd be reconnecting.

If the camera finds a broken lateral after we close, can MAWSS fix it?

Not on the private side. MAWSS maintains the public lateral and the main, and says anything past the property line is the homeowner's responsibility. That is why the scope belongs before closing: once the deed records, a cracked clay lateral or a MAWSS defect letter is the new owner's to deal with.

Sewer Scope Inspection in Mobile, AL

Cost: a scope is priced as a sewer camera inspection; the national ranges are on the camera inspection page.
Housing age: the median Mobile home was built in 1976, and about 60% of homes before 1980 (Census ACS 2024).
Who carries the risk: MAWSS policy makes the property owner responsible for checking that an existing lateral works, and MAWSS isn't liable for damage from a defective or capped one.
Vacant houses: MAWSS may cap the sewer at a property empty for more than five years, and reopening it costs normal new-service fees.

Mobile Sewer Line Replacement puts home buyers in touch with a plumber about filming the sewer line before a sale. A sewer scope is a camera pushed through a cleanout and along the private lateral; ask for a video that shows what the pipe is made of, where joints have opened, and how far from the house each defect sits.

Sewer Scope Inspection Before and After a Sale

The camera work is the same in every case. What changes is who orders it, when, and what the video has to answer.

Buyer's Pre-Purchase Camera Run

Book it inside the inspection period, so a bad result can still go into the repair request or the price. Ask for the run to start at a cleanout and go all the way to the property line, and for the distance to show on screen at every defect. If there's no cleanout, ask how the camera got in and how far it went.

Seller's Camera Run Before the House Lists

A seller who films the line first knows what a buyer's scope will find and can fix it, price it in, or disclose it. If the line was replaced, put the invoice, permit and inspection sticker in front of buyers alongside the video; those are the documents MAWSS asks for as proof of a replacement.

Scope on a House Built Before 1976

MAWSS says about three-quarters of the private laterals in its program description were laid before 1976, mostly in clay with a joint every few feet; the details and what fails are on the clay sewer pipe page. Houses of that age may also have Orangeburg pipe, the bituminous fiber pipe used into the 1970s.

Re-Scope After a Repair, for Closing

When a repair is a condition of the sale, film it again after the work. For pipe bursting, Mobile's 2021 code already wants recorded video after the new pipe is in. A re-scope also matters if a MAWSS defect letter is involved, because MAWSS may re-test the line at any time.

Inspector's Scope or Plumber's Scope

Whoever runs the camera, a home inspector or a plumber, ask for the video file itself, not only a written summary. If the person filming also quotes the repair, ask for the quote on paper separately, so a second plumber can price the same footage.

What to Ask For With the Scope Video

Material changes
Where cast iron becomes clay or PVC, and whether earlier spot repairs show up as short new sections.
Water standing in the pipe
A dip that holds water is a belly, and the scope should say how long it is.
Roots and offsets
Roots at joints mean open joints; see tree root repair.

After Closing, the Lateral Is Yours

In Mobile the private lateral belongs to the property owner, and MAWSS sends defect notices to the owner, with a deadline and penalties that the sewer line repair page explains. A scope that finds trouble before closing turns that future bill into a negotiating point. A scope that comes back clean is worth keeping on file for your own sale.
