Plumbing
Step-by-step plumbing repairs and fixture comparisons you can do yourself — from leaky faucets and running toilets to clogs, bidets, and water filters.
Most plumbing jobs that send people scrambling for a professional are simpler than they look — a worn washer, a misaligned flapper, a clogged trap. The catch is that plumbing punishes guesswork: a wrong turn on a fitting under pressure becomes a leak inside a wall, not a lesson learned. Our guides assume you'd rather spend an afternoon and a few dollars than a service call, but they also flag exactly where a job stops being safe for a weekend fix.
We write these from the perspective of someone who has opened enough cabinets to know which fittings actually seize, which cartridges are worth rebuilding versus replacing, and which drain problems need a cable instead of a chemical. Every step is grounded in how parts actually behave — not how the packaging promises they will.
Work methodically, shut the water off first, and when a guide tells you to stop and call a licensed plumber, believe it. The best repair is the one that doesn't turn into a re-flood.

Read GuideFrequently Asked Questions
Why does my faucet keep dripping after I replace the washer?
A persistent drip after a washer swap almost always means the seat is pitted or the cartridge is worn, not that you chose the wrong washer. Inspect the valve seat for grooves and either dress it with a seat tool or replace the cartridge outright.
Is a running toilet really wasting that much water?
Yes — a toilet that runs constantly can silently pass hundreds of gallons a month through the overflow tube. The most common culprit is a failing flapper that no longer seals, a fix that typically costs a few dollars and takes minutes.
Are chemical drain cleaners safe for my pipes?
Repeated use of caustic or acidic cleaners can degrade metal traps and old pipe joints, and they rarely clear a full blockage. Mechanical methods — a plunger, a drain snake, or removing the trap — are safer and actually remove the obstruction instead of burning a hole through it.
When should I stop trying to fix it myself?
Stop when you're dealing with a main-line blockage, a leak inside a wall or slab, anything requiring you to work on a pressurized supply line without a shutoff, or gas water heater components. Those are the jobs where the downside of a mistake exceeds any money saved.
