Plumbing is an essential part of our homes, and understanding how it works can save you time, money, and stress. While plumbers are the experts in fixing plumbing issues, there are some secrets of the trade that they may not readily share. In this article, we’ll delve into 30 plumbing secrets that your plumber might not reveal. These insights will empower homeowners to take better care of their plumbing systems, prevent common problems, and even troubleshoot minor issues.

1. Locate Your Main Water Shut-Off Valve:

Know the location of your main water shut-off valve. It’s crucial in emergencies to turn off the water supply to your entire home quickly.

2. Insulate Pipes for Winter:

Prevent frozen pipes by insulating them, especially in cold climates. Frozen pipes can lead to costly damage and inconvenience.

3. Watch What You Flush:

Plumbers often find clogs caused by flushing items like wipes, cotton balls, and paper towels. Stick to flushing toilet paper only.

4. Know Your Water Pressure:

Excessive water pressure can strain your plumbing system. Use a pressure gauge to measure your water pressure and adjust it if necessary.

5. Regularly Clean Faucet Aerators:

Mineral buildup in faucet aerators can reduce water flow. Remove and clean them periodically to maintain strong water pressure.

6. Be Careful with Chemical Drain Cleaners:

Chemical drain cleaners can damage pipes over time. Opt for natural alternatives like baking soda and vinegar or use a drain snake.

7. Install Water Softeners if Necessary:

Hard water can cause mineral buildup in pipes and appliances. Consider a water softener system to prolong the life of your plumbing.

8. Use Mesh Drain Covers:

Prevent hair, debris, and foreign objects from entering drains with mesh drain covers. Regular cleaning is easier than dealing with clogs.

9. Avoid Over-Tightening Faucets:

Over-tightening faucet handles can damage them. Turn faucets off gently to avoid wear and tear.

10. Check for Leaky Toilets:

A running toilet can waste a significant amount of water. Listen for running water and check for leaks periodically.

11. Invest in a Plunger:

Every household should have a plunger. It’s a simple tool that can quickly resolve minor clogs in sinks and toilets.

12. Keep an Eye on Water Bills:

Unexplained increases in water bills can signal hidden leaks. Investigate promptly to prevent further damage.

13. Test Your Sump Pump:

If you have a sump pump, test it regularly to ensure it’s functioning correctly, especially during rainy seasons.

14. Inspect for Leaky Faucets:

Even small leaks can waste water and money. Fix leaky faucets promptly to prevent water damage and save on utility bills.

15. Know How to Shut Off Individual Fixtures:

Familiarize yourself with the shut-off valves for each fixture in your home. This can be handy when you need to make repairs.

16. Keep Drains Clear of Grease:

Grease can solidify in pipes and cause clogs. Dispose of cooking grease properly, rather than washing it down the sink.

17. Flush the Water Heater Annually:

Flushing your water heater removes sediment buildup and ensures it operates efficiently and lasts longer.

18. Don’t Ignore Dripping Faucets:

Persistent dripping not only wastes water but can also lead to fixture damage. Address drips early to prevent costly repairs.

19. Use Teflon Tape:

Plumbers use Teflon tape to seal threaded connections. Keep some on hand for small DIY plumbing projects.

20. Be Cautious with DIY Plumbing:

While small plumbing tasks can be DIY, complex issues require professional help. Attempting complex repairs can worsen the problem.

21. Install Water Hammer Arrestors:

Water hammer occurs when water suddenly stops or changes direction in pipes. Installing water hammer arrestors can prevent noisy pipes.

22. Test Toilet Flappers:

A faulty toilet flapper can waste water. Test it by adding a few drops of food coloring to the tank; if it seeps into the bowl without flushing, replace the flapper.

23. Check for Slow Leaks:

Slow leaks are often silent but can cause substantial damage over time. Look for water stains and inspect hidden areas regularly.

24. Be Mindful of Drain Snakes:

While drain snakes are useful, improper use can damage pipes. If you’re unsure, consult a professional.

25. Inspect Washing Machine Hoses:

Check washing machine hoses for cracks or bulges. Replacing them with stainless steel braided hoses can prevent costly floods.

26. Use Enzyme-Based Drain Cleaners:

Enzyme-based drain cleaners break down organic material and are less harmful to pipes than chemical cleaners.

27. Maintain Water Heater Temperature:

Set your water heater to a safe but not scalding temperature. This prevents burns and conserves energy.

28. Regularly Clean Showerheads:

Mineral buildup can reduce water flow from showerheads. Soak them in vinegar to remove deposits and restore water pressure.

29. Install a Water Filtration System:

A whole-house or under-sink water filtration system can improve water quality and reduce the risk of pipe corrosion.

30. Schedule Regular Plumbing Inspections:

Consider having a professional plumber inspect your plumbing system periodically. They can identify potential issues before they become major problems.


Understanding these 30 plumbing secrets can help homeowners maintain a well-functioning plumbing system, prevent common issues, and address minor problems promptly. While some tasks are suitable for DIY enthusiasts, complex plumbing issues should always be entrusted to a qualified plumber to avoid costly mistakes and ensure the longevity of your plumbing infrastructure.
