7 Common Plumbing Problems and Their Causes

Dripping Faucets and Running Toilets

A dripping faucet is more than an annoyance. Those steady drips waste a surprising amount of water over time and drive up your bill. The cause is usually a worn washer, O-ring, or cartridge inside the faucet that no longer seals properly.

A running toilet is another quiet water waster. It's often caused by a worn flapper that won't seal, a faulty fill valve, or a chain that's tangled or the wrong length. Both problems are common, and both are worth fixing promptly since the wasted water adds up quickly.

Clogged Drains

Slow or clogged drains are among the most frequent plumbing complaints. In kitchen sinks, grease, food scraps, and soap buildup are the usual culprits. In bathrooms, hair and soap scum tend to be the problem.

A single slow drain usually points to a local clog near that fixture. When multiple drains back up at once, the issue may be deeper in your main sewer line, which is a bigger problem that typically needs professional attention.

Low Water Pressure

Weak water pressure makes showers and chores frustrating. Sometimes the cause is simple, like mineral buildup clogging a faucet aerator or showerhead, which you can often clean or replace yourself.

When low pressure affects the whole house, the cause may be a hidden leak, corroded pipes, a problem with a pressure regulator, or an issue with the municipal supply. Widespread pressure problems are worth investigating because they can point to something more serious in your system.

Leaky Pipes and Water Heater Issues

Leaky pipes waste water and can cause serious damage if they go unnoticed. Leaks often develop at joints and are more likely with age, corrosion, high water pressure, or shifting pipes. Warning signs include water stains, warped walls, musty smells, and unexpectedly high bills.

Water heater trouble is another common issue, showing up as inconsistent hot water, discolored or rusty water, or noises from the tank. Because leaks and water heater failures can escalate quickly, they're best addressed sooner rather than later.

Sump Pump and Sewer Line Problems

If your home has a sump pump, a failure can lead to a flooded basement during heavy rain. Pumps can fail from age, power outages, stuck switches, or clogs, so testing yours before wet season is wise.

Sewer line problems are among the most disruptive. Multiple slow drains, gurgling sounds, sewage odors, or backups all point to a main line issue, which can be caused by tree roots, buildup, or damaged pipes. These problems almost always require professional diagnosis and repair.
