5 Common Plumbing Problems and How to Fix Them

Plumbing issues can quickly turn from minor annoyances into costly structural damage if left unchecked. Here is how top trade professionals diagnose and resolve common issues.

1. Dripping Faucets

Often caused by worn O-rings or damaged ceramic cartridges. Replacing internal seals restores a drip-free operation immediately.

2. Low Water Pressure

Accumulated mineral scale in aerators or shut-off valves is usually the main culprit. Cleaning aerators or installing pressure booster pumps resolves flow issues.

3. Clogged Drain Lines

Avoid harsh chemical cleaners that damage PVC pipes. Use mechanical drain augers or hydro-jetting equipment for safe blockage removal.

4. Running Toilets

A damaged flapper valve or miscalibrated fill valve causes continuous water waste. Inspect and replace fill valve assemblies promptly.

5. Leaking Water Heaters

Check temperature-pressure relief (TPR) valves and inlet connections. Corroded tank walls indicate it is time for a modern replacement unit.
