Essential Plumbing Maintenance Tips to Avoid Costly Repairs
Why Plumbing Maintenance Saves You Money
The average plumbing emergency costs homeowners $300 to $1,500 to fix. Water damage from a burst pipe or major leak can push that number into the tens of thousands. Yet most plumbing emergencies are entirely preventable with basic maintenance.
Spending a little time and attention on your plumbing system now saves you from stress, damage, and expensive repairs later.
Monthly Plumbing Maintenance Tasks
Check for Leaks
Walk through your home and inspect visible pipes under every sink, behind toilets, and around your water heater. Look for:
- Drips or moisture on pipe joints
- Water stains on cabinets or walls
- Musty odors that suggest hidden moisture
- Puddles or dampness around appliance connections
Even a small drip wastes gallons of water per day and can cause mold growth or structural damage over time.
Test Your Water Pressure
High water pressure — above 80 psi — puts unnecessary stress on your pipes, fittings, and appliances. Purchase an inexpensive pressure gauge from any hardware store, attach it to an outdoor spigot, and check your reading.
If your pressure exceeds 80 psi, install a pressure-reducing valve or have a professional plumber adjust your existing one.
Run Unused Drains
Drains in guest bathrooms, utility sinks, and basement floor drains can dry out if not used regularly. When the water in the P-trap evaporates, sewer gas can seep into your home. Run water through unused drains for 30 seconds each month to keep the trap sealed.
Seasonal Plumbing Tasks
Spring
- Inspect outdoor faucets and hose bibs for freeze damage from winter
- Check exposed pipes in crawl spaces for signs of leaks
- Clean gutters and ensure downspouts drain away from the foundation
- Test your sump pump by pouring water into the pit
Summer
- Check washing machine hoses for bulges, cracks, or brittleness
- Inspect sprinkler systems for leaks and broken heads
- Clean shower heads with vinegar to remove mineral buildup
Fall
- Disconnect and drain garden hoses before the first freeze
- Insulate exposed pipes in unheated areas like garages, attics, and crawl spaces
- Locate your main water shut-off valve and make sure it works — you’ll need to find it fast in an emergency. Our emergency plumbing guide covers this in detail.
Winter
- Keep your thermostat set to at least 55 degrees, even when traveling
- Open cabinet doors under sinks on exterior walls during freezing weather
- Let faucets drip slightly during extreme cold snaps to prevent pipe freezing
What to Never Put Down Your Drains
Clogged drains are the most common plumbing problem, and most clogs are caused by what homeowners put down them. Avoid these drain destroyers:
- Grease and cooking oil — they solidify in pipes and create stubborn blockages
- Coffee grounds — they accumulate and form a sludge
- “Flushable” wipes — they don’t break down like toilet paper and clog sewer lines
- Hair — use drain screens in showers and bathroom sinks
- Eggshells and fibrous foods — they tangle in garbage disposal blades
The Smart Approach to Drain Care
Use a mesh drain screen in every shower and sink. Clean these screens weekly. If a drain slows down, try a mixture of baking soda and vinegar before reaching for chemical drain cleaners, which can corrode older pipes.
Know When to Call a Professional
Some plumbing tasks are straightforward for handy homeowners. Others require a licensed plumber to handle safely:
DIY-friendly: Replacing a faucet aerator, fixing a running toilet, clearing a minor clog with a plunger
Call a pro: Anything involving your main sewer line, water heater repairs, low water pressure throughout the house, or visible pipe corrosion
If you’re unsure, it’s always better to call a professional than risk turning a small problem into a large one. Learn more about finding a reliable plumber you can trust.
