Buying a home is expensive, and sewer-line problems can be among the most disruptive surprises. Before closing, it’s smart to verify that the main sewer line from the house to the municipal connection—or to a septic system, depending on the property—is functioning properly and is in good condition.

While home inspectors may note obvious issues, the most reliable way to assess sewer lines is usually a targeted inspection using a specialized video camera and, when appropriate, pressure testing.

1) Start with what you can learn before any invasive work

Ask for existing documentation first. Request any prior plumbing or sewer work invoices, past inspection reports, and information about cleanouts, prior backups, or recurring odors. If the home has older cast-iron piping or is in an area known for tree roots or shifting soils, flag that for the inspector.

Sewage backflow can occur when a municipal sewer line surcharges or when downstream conditions prevent wastewater from draining properly. In those situations, plumbing fixtures can become conduits for contamination, creating health and property risks. A backwater valve—also called a backflow preventer for sanitary sewer systems—helps block reverse flow and can protect basements, drains, and lower-level toilets or shower drains.

While the concept is straightforward, installation details matter. A correctly sized and properly positioned valve, paired with appropriate piping and testing, is what determines whether it will perform during a real backup event.

What a backwater valve does

Under normal use, wastewater flows away from the building through a valve body and into the sewer. When the direction reverses—such as during a backup—the valve closes, preventing sewage from traveling back in ... Read more »

When a drain won’t flow, plumbers often turn to rodding—a method that pushes a tool through a pipe to break up or remove the blockage. Two common options are main line rodding and power rodding. While both aim to clear the line, they use different mechanics and are typically chosen for different blockage types and risk levels.

Main line rodding: manual control for typical clogs

Main line rodding is generally a manual or hand-operated approach. A rod or cable is fed into the drain and advanced through the pipe while a technician applies controlled force to break up the obstruction. Because the operator can feel resistance and adjust pressure, this method is often favored for more routine situations where the clog is not extreme.

It’s commonly used for issues like hair, soap buildup, minor grease deposits, or partial bl ... Read more »

A properly maintained basement floor drain helps manage groundwater, wash-out from sump events, and occasional debris. When a floor drain clogs, the result can range from slow drainage and foul odors to water backing up during heavy rains or appliance use.

The goal of maintenance is simple: keep the drain pathway clear, prevent buildup in the trap or pipe, and ensure any connected sump/discharge route is functioning. Regular attention—especially in seasons with higher moisture—often prevents emergency cleanouts.

1) Start with safe inspection and identification

Before cleaning, confirm what you’re dealing with. Some basement floor drains connect to a dedicated sump pump system, while others tie into a main sewer line (often with a check valve). Look for visible debris near the grate, check for standing water, and note whether there’s a vented smell or gurgling when water ... Read more »
