The Top 10 Plumbing Questions Homeowners Ask

EST Read Time: 5 min

Plumbing problems often strike when least expected—overflowing toilets, dripping faucets, or a mystery puddle under the sink. These aren’t just annoyances; they waste water, inflate bills, and can cause costly damage. Below are the ten questions homeowners ask most, with answers from professionals who solve these issues every day.

Why is my toilet running constantly?
Likely a faulty flapper valve or misaligned float. Replace the flapper, adjust the chain, and ensure the fill line isn’t inside the overflow pipe.

1. Why do my drains clog so often?
   Hair, grease, and soap residue build up inside pipes. Use a drain strainer and avoid pouring oils or coffee grounds down the sink.

2. Are chemical drain cleaners safe?
   No—most corrode pipes and harm septic systems. Choose enzymatic cleaners or call a plumber for mechanical removal.

3. Why does my hot water run out so fast?
   Sediment buildup or a worn heating element reduces efficiency. Flush the tank annually and check the thermostat setting (120°F ideal).

4. What causes low water pressure?
   Corroded pipes, mineral-filled aerators, or a faulty pressure regulator. Clean aerators and inspect shut-off valves before calling a pro.

5. How do I prevent frozen pipes?
   Insulate exposed lines, let faucets drip on freezing nights, and keep cabinet doors open to circulate warm air.

6. Where’s my main shut-off valve?
   Usually near where the water line enters the house. Label it clearly—this valve stops catastrophic leaks fast.

7. How long should my water heater last?
   Standard tanks: 8–12 years. Tankless: 20+. Flush yearly, check the anode rod, and maintain 120°F to extend life.

8. What shouldn’t I put down the drain?
   “Flushable” wipes, fats, oils, coffee grounds, hair, paint, or harsh chemicals.

9. When should I call a professional?
   For sewer backups, major leaks, or water heater failures. If you’re unsure—don’t risk it.
