A single faucet dripping once per second wastes over 2,600 gallons of water annually, according to Happy Hiller. This guide helps homeowners, armed with basic tools and knowledge, tackle many common plumbing issues themselves. Resolving these water-wasting problems saves money and protects your home from potential damage.

What Are Common Plumbing Issues?

Common plumbing issues are the recurring problems most homeowners face, typically involving faucets, drains, and toilets. These issues often stem from the daily wear and tear on fixtures and pipes. A leaky faucet, for instance, is frequently caused by a simple deteriorating washer that no longer creates a tight seal. Similarly, a constantly running toilet can often be traced back to a faulty rubber flapper or an improperly set water level in the tank. Clogged drains and toilets are another prevalent issue, usually resulting from an accumulation of hair, soap scum, or items that shouldn't be flushed. Finally, low water pressure, when isolated to a single fixture, is commonly due to mineral deposits building up in the aerator, restricting water flow.

How to Fix Common Plumbing Issues: Step by Step

Always turn off the water supply to the fixture before beginning any repair. The following steps detail how to resolve common plumbing problems in your home.

How to Fix a Leaky Faucet Step-by-Step

A dripping spout is the classic plumbing problem, and the cause is almost always a worn-out internal part. For traditional compression-style faucets, a small rubber washer is the usual culprit. For leaks around the base of the handle, a failing O-ring is often to blame.

  1. Step 1: Gather Your Tools and Parts — Before you start, collect an adjustable wrench, a flathead and Phillips head screwdriver, rags, and a replacement washer or O-ring kit. These kits are inexpensive and available at any hardware store; it's wise to have one on hand.
  2. Step 2: Shut Off the Water Supply — Look for the small shut-off valves on the hot and cold water pipes beneath the sink. Turn the handles clockwise until they are fully closed. Turn the faucet on to drain any remaining water from the lines.
  3. Step 3: Disassemble the Faucet Handle — Most handles have a decorative cap on top. Gently pry this off with a flathead screwdriver to reveal a screw. Remove the screw, and then lift the handle straight off the faucet body.
  4. Step 4: Access the Internal Parts — With the handle removed, you will see the valve stem or packing nut. Use your adjustable wrench to carefully loosen and remove this component. This will expose the washer (often held by a brass screw at the bottom of the stem) or the O-rings around the stem.
  5. Step 5: Replace the Worn Component — Remove the screw holding the old washer and replace it with a new one that is an exact match. If you are fixing a leak at the base, slide off the old O-rings and roll the new ones into place. A little plumber's grease can help create a better seal.
  6. Step 6: Reassemble and Test — Carefully reassemble the faucet in the reverse order you took it apart. Once everything is snug, slowly turn the water supply valves back on. Turn the faucet on and off, checking carefully for any drips or leaks.
