A constantly dripping faucet wastes water and can stain the sink. Most leaks come from a worn washer, O-ring, or cartridge — and the repair is one of the easiest plumbing fixes you can do at home.

Replacing a toilet is a great weekend project that can refresh a bathroom and stop leaks for good. With a helper, a wax ring, and an hour or two of patience, you can swap it out yourself.

Before you call anyone, most slow or stopped drains can be cleared in a few minutes with tools you probably already own. Start gentle and only step up if you have to.

Swapping a shower head is one of the fastest upgrades in the house. You don't even need to turn off the water — just unscrew the old one and screw on the new.
