None of this requires tools or expertise — just a few minutes once a month to catch the kind of small issues that turn into expensive ones if they're left alone.
Why monthly, not yearly
Most plumbing damage doesn't happen all at once. A slow drip, a slightly loose fitting, or a weeping valve can sit there for months doing quiet damage before it's obvious. A short monthly check catches these while they're still cheap, easy fixes.
Do
- Check under every sink for dampness, mineral buildup, or a musty smell
- Look at the area around your water heater for any signs of moisture
- Test that all shut-off valves under sinks and toilets still turn
- Glance at exposed pipes in the garage, basement, or crawl space for corrosion
- Check outdoor hose bibs and irrigation lines for drips, especially after using them
Don't
- Don't skip the check just because nothing seems wrong — early leaks are often silent
- Don't ignore a faint musty smell under a cabinet, even without visible water
- Don't assume a valve that won't turn easily isn't worth addressing
Quick tip: Keep a small flashlight under your kitchen sink — it makes spotting early moisture or corrosion in tight spaces much easier during your monthly check.
