Bathroom sink clogs are usually blamed on hair, and that’s not entirely wrong. But many stubborn slow-drains and near-blockages are caused by a wider mix of materials that collect in pipes over time. Understanding what’s actually building up can make fixes faster and reduce the chance of repeat clogs.

Soap scum and detergent buildup

Even when you don’t notice it, bathroom sink plumbing can collect soap scum—a sticky combination of soap residues and minerals from water. This buildup can cling to pipe walls, narrowing the passage until water drains slowly or backs up around the overflow.

Toothpaste, mouthwash, and shaving residue

Toothpaste contains ingredients that can leave behind a film, especially when combined with water and brushing spatter. Mouthwash additives and shaving residue can add to that problem by introducing waxy or oily components that coat surf ... Read more »

When a storm surge (or heavy rainfall) forces water up and back through a home’s basement drain, the situation can turn dangerous quickly. Backup water may carry sewage, chemicals, and debris, raising risks ranging from contamination to electrical hazards.

Act immediately to reduce risk

The first priority is safety. Keep people and pets away from the affected area, and avoid touching standing water if you suspect it may be contaminated. If water is near outlets, wiring, or appliances, do not handle electrical fixtures—shut off power to the impacted circuits from the breaker if you can do so safely.

Next, limit additional water intrusion. If your home has a basement drain system connected to a sump pump, check whether the pump is running and free of obvious blockages. During dangerous flooding conditions, avoid going into deep water.

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 »
