That running toilet, dripping faucet, or jammed garbage disposal doesn’t have to be a mystery, or an automatic call to a plumber. Learn how your kitchen and bathroom plumbing works, why it fails, and which repairs you can tackle yourself.
We’ll start with a cutaway toilet so you can see the hidden workings in action. Learn what each part does, how to pinpoint a problem, and how to replace the parts responsible for constant running, weak flushes, and leaks.
Next, get acquainted with the shutoff valves under your sink: why they leak or seize, what to do when they won’t shut off, and how to repair or replace them.
Then we’ll throw in the kitchen sink! Explore how to troubleshoot and repair leaking drains and faucets, safely clear a jammed garbage disposal, and recognize when replacement makes more sense.
We’ll wrap up by making sense of common household pipes and fittings—how they’re sized, which connections use threads, how different joints seal, and when to use thread tape, sealant, or neither.
Leave with practical skills, smarter troubleshooting habits, and the confidence to tackle common plumbing problems—and to know when to call a professional.
