When you’re building a home inspection checklist, drain and sewer inspection belongs near the top of the “systems” section. Unlike visible plumbing fixes, problems in sewer lines can stay hidden for years—until slow drains, foul odors, or water damage appear.

What a “drain/sewer inspection” typically covers

In most home inspections, this does not mean a full excavation or engineering assessment. Instead, it generally focuses on observable conditions, functional testing, and records review, plus guidance on when a specialist (like a licensed plumber or sewer camera technician) should step in.

A solid checklist item usually includes verifying accessible interior drain components, checking how fixtures perform during operation, and assessing any available information about the main line and sewer connection.

Checklist items to add

As temperatures drop, residential plumbing becomes more vulnerable to freezing, blockages, and drainage issues. Winterizing your drains early can reduce the risk of backup problems and keep sinks, tubs, and toilets flowing smoothly through the cold season.

Why winterizing matters

When water can’t move freely, it tends to linger in pipes—especially in slower drains or vulnerable sections of plumbing. In freezing temperatures, trapped water may expand, contributing to pipe damage. Meanwhile, colder conditions can worsen existing buildup from grease, soap scum, hair, and debris, leading to stubborn clogs.

Start with a drain “reset”

Begin by clearing each household drain you rely on most. Remove visible hair or gunk from strainers, and flush drains with hot water where appropriate (and safe for your plumbing). If a drain is already sluggish, addressing buildup befo ... Read more »

Illinois homeowners know the rhythm: snow piles up, then temperatures swing, and spring runoff arrives fast. If drainage systems aren’t ready, that surge can lead to overflowing gutters, basement seepage, soggy lawns, and erosion around foundations. A quick spring drain check can prevent small blockages from turning into costly repairs.

Start with the roofline: inspect gutters and downspouts for winter debris such as leaves, twigs, grit, and ice-dam residue. Look for sagging sections, separated joints, and signs of water spilling over the edges during melt periods. Clear visible clogs and flush downspouts with a hose to confirm water flows freely.

Move to downspout discharge: make sure downspouts extend far enough away from the house, typically several feet, so runoff doesn’t pool at the base. Check for splash blocks or underground extensions that may have shifted during freeze-thaw cycles. I ... Read more »

A clogged drain is a common household problem—but the right fix depends on what’s causing the blockage. While many plumbing issues can be handled by a general plumber, certain drain and sewer problems often require the tools, diagnostics, and specialized experience of a drain specialist.

Knowing which professional to call can save time, limit property damage, and reduce the chance of the problem coming back soon.

When a general plumber is usually enough

If the issue appears localized and straightforward, a general plumber can often resolve it quickly. Typical examples include a single-sink clog, a slow-draining bathroom fixture, or a straightforward blockage accessible from the home’s plumbing system.

In these cases, a general plumber may use standard drain cleaning methods (such as handheld equipment or basic augers) and inspect nearby connections to confirm there&rsquo ... Read more »
