Plumbing problems can be confusing, inconvenient, and sometimes costly 💧. Whether you’re a homeowner, tenant, or business owner, it helps to know the basics. Here’s a list of 25 of the most common plumbing questions — answered clearly by professionals 🛠️.
💡 General Plumbing Questions
1. What causes low water pressure in my house?
Often due to clogged pipes, partially closed valves, or issues with the municipal supply.
2. Why does my faucet drip?
A worn-out washer or faulty valve seat is usually to blame.
3. Can I use chemical drain cleaners?
Not recommended — they can corrode pipes over time. Use enzyme-based cleaners or a plumber’s snake instead.
4. How do I shut off the main water supply?
Locate the main shut-off valve, typically near the water meter or where the line enters your home. Turn it clockwise.
5. Why do my pipes rattle or make noise?
This could be “water hammer,” caused by sudden water stoppage. It may require installing air chambers or arrestors.
🚽 Bathroom Plumbing FAQs
6. Why does my toilet keep running?
Usually a faulty flapper, fill valve, or float. These are inexpensive to replace.
7. What causes a slow-draining sink or tub?
Hair, soap scum, and debris buildup are common causes.
8. How can I prevent clogs in the shower drain?
Use a drain cover to catch hair and clean it regularly.
9. Why does my bathroom smell like sewage?
Dry P-traps or a venting issue can cause foul smells. Run water to refill traps or call a plumber.
10. Is it normal for water to come up when I flush the toilet?
No — that’s a sign of a potential clog or a sewer backup.
🍳 Kitchen Plumbing FAQs
11. Can I put grease down the drain?
Never! Grease hardens and causes serious clogs. Dispose of it in the trash.
12. Why is my garbage disposal humming but not working?
It may be jammed. Turn off the power and use an Allen wrench to manually free it.
13. Can I install a dishwasher myself?
Yes, but it requires water, electrical, and drain hookups. Consider hiring a pro to avoid leaks.
14. Why does my sink smell bad?
Likely food buildup in the disposal or pipes. Clean with baking soda, vinegar, and hot water.
15. How do I fix a leaky kitchen faucet?
Shut off the water, disassemble the handle, and replace worn washers or cartridges.
🔧 Maintenance & Emergencies
16. How often should I inspect my plumbing?
Annually. Regular checks can catch small issues before they become expensive.
17. What should I do during a plumbing emergency?
Turn off the water supply and call a licensed plumber immediately.
18. Is it safe to DIY plumbing repairs?
Minor fixes like replacing a washer are fine, but leave pipe replacements and gas line work to pros.
19. How can I prevent frozen pipes in winter?
Insulate exposed pipes, leave cabinets open, and keep a trickle of water running during deep freezes.
20. What should I do if a pipe bursts?
Shut off the main water supply, open taps to drain the system, and call a plumber ASAP.
🧰 Plumbing Upgrades & Water Heaters
21. How long does a water heater last?
Typically 8–12 years. Tankless models may last longer.
22. Should I go tankless?
Yes if you want energy savings, unlimited hot water, and more space — but the upfront cost is higher.
23. What are signs my water heater is failing?
Rusty water, loud noises, leaks, or inconsistent temperatures.
24. Can a plumber install a new bathroom?
Yes, from rough-in plumbing to fixture installation — they handle it all.
25. How do I choose a good local plumber?
Look for licensed, insured professionals with good reviews and transparent pricing.
