Plumbing

Plumbing you can handle — and the parts you shouldn't

Plumbing punishes hesitation. Know where the shut-offs are before you need them, and treat any repair involving gas, sewer gas, or a wall cavity as a professional job.

Common problems and what they usually mean

Toilet runs between flushes

Most likely
Failed flapper or a fill valve set too high
DIY approach
Shut the stop, flush dry, swap the flapper, set the water line an inch below the overflow.
When to call a pro
Rarely needed.
Typical cost
$6–$25 in parts

Low water pressure at one fixture

Most likely
Clogged aerator or a partially closed stop
DIY approach
Unscrew the aerator, rinse the screen, verify the stop is fully open.
When to call a pro
If pressure is low house-wide, have the pressure regulator checked.
Typical cost
$0–$12

Drain is slow, then clogs

Most likely
Hair and soap buildup within the first few feet
DIY approach
Clean the pop-up, then use a hand auger. Skip caustic chemicals.
When to call a pro
Repeat backups in multiple fixtures suggest a main line issue.
Typical cost
$20–$35 for an auger, or roughly $175–$450 for a pro clearing

Water heater makes popping sounds

Most likely
Sediment on the tank bottom from hard water
DIY approach
Flush the tank annually and set the thermostat to 120°F.
When to call a pro
Rust-colored water, a weeping T&P valve, or any scorching.
Typical cost
$0 to flush, or roughly $1,400–$2,600 to replace

Checklist

  • Test the main shut-off once a year so you know it turns
  • Replace supply lines older than ten years with braided stainless
  • Insulate exposed pipe before the first hard freeze
  • Disconnect hoses and cover hose bibs every November
  • Flush the water heater annually in hard-water areas

Safety first

  • Never work on a gas water heater connection yourself
  • Sewage backup is a health hazard — call a professional
  • If you cannot find the shut-off, do not start the repair
