Hey neighbor, let's talk plumbing.

Most plumbing 'emergencies' start as tiny drips. Fix the tiny stuff on a Saturday and you'll almost never meet a real one.

Red flags

When to worry.

Water bill jumped

Silent toilet leak, ten times out of ten. Drop food coloring in the tank, if it hits the bowl, replace the flapper.

Slow drain

Hair or grease. Try a hand-crank drain snake before any chemicals, they eat pipes.

Musty smell near a wall

Slow leak inside the wall. Do not wait on this one.

Do it yourself

The DIY walkthrough.

Do these in order. Skip anything that doesn't apply, Olivia won't mind.

  1. 01
    Step 1 of 5

    Find your main water shutoff

    Basement, crawlspace, or where the line enters the house. Everyone in the family should know where it is.

    Step 2 of 5

    Clean the P-trap under the slow sink

    Bucket underneath, unscrew the two slip nuts, dump the gunk, rinse, reassemble. Ten-minute fix.

  3. 03
    Step 3 of 5

    Check under every sink monthly

    Feel the pipes. Any dampness? Track it up until you find the source.

    Step 4 of 5

    Test the toilet flapper

    Push the flush lever. If water keeps running, the flapper is worn. Ten-dollar part, ten-minute swap.

  5. 05
    Step 5 of 5

    Insulate exposed pipes before winter

    Foam pipe sleeves are two bucks and prevent burst-pipe disasters.

Tools you'll want

  • Adjustable wrench
  • Channel-lock pliers
  • Bucket
  • Plumber's tape (PTFE)
  • Drain snake
  • Flashlight
When to call a pro

Water running where it shouldn't?

Shut off the main, then call a licensed plumber. Anything involving the water heater, sewer line, or hidden pipes is not a DIY fix.

Quick answers

Olivia's FAQ.

01Is chemical drain cleaner ever okay?

As a very last resort. It corrodes pipes and can splash back. A snake or enzyme cleaner is safer.

02Why does my toilet 'ghost flush'?

Flapper leak. Water slowly drops in the tank until the fill valve kicks on. Replace the flapper.

03How hot should my water heater be?

120°F is the sweet spot. Hotter risks scalding and wastes energy.

04What's a water hammer?

That loud thunk when you close a tap fast. Usually an air-chamber problem, a plumber can fix it in an hour.
