Gurgling noises from the toilet mean there's negative air pressure in the drain line. Air should flow freely through these lines to allow waste to exit the home. When suction builds, air comes back through the drainpipe — and you hear it.

This occurs because there's a clog somewhere in the line. Never allow this to persist — the problem could be a collapsed or broken sewer line.

Water heaters fail for a variety of reasons. Many times, the problem is a faulty heating element — a quick and inexpensive fix. A malfunctioning thermostat could also be the culprit.

If you hear water in the pipes when nothing is running, you likely have a leak. Quick action keeps the water bill down and reduces the risk of mold and mildew.

When you notice a sudden drop in water pressure, first check with neighbors to see if it's a municipal issue. If it's only your home, the problem could be internal:

A single slow drain suggests a localized clog. When multiple drains in the home move slowly, the problem may lie in the main sewage line.

Clogs can be caused by anything — from a child's toy to food waste to a small rodent. Professional drain snakes and augers are far more effective than anything a homeowner has.

A sewage smell in the home can come from multiple sources. A plumber can run a camera through the sewer lines to locate the exact problem.

Pipes exposed to extreme cold — especially in crawl spaces, unheated areas, and exterior walls without adequate insulation — remain at substantial risk of freezing. Prevention is always the best strategy.

If a pipe does freeze, begin thawing by allowing water to trickle from the faucet. While waiting, call a plumber — they need to examine the pipe and ensure there are no leaks or cracks.
