Fill a clear glass straight from the tap and hold it up to the light.

The vanity in the hall bathroom holds the usual inventory: a hair dryer with its cord wound around it, a basket of half-used bottles, a stack of towels somebody folded once, and a box nobody has opened since the move.

You reach down to unscrew the garden hose from the spigot, and instead of the hose letting go, the whole faucet turns with it.

You turn on the shower, and the strong spray you had yesterday is now a weak trickle. A sudden loss of water pressure is jarring because it happens overnight — everything was fine, and now it's not. That suddenness is actually a useful clue, because it points to something that changed: a leak that opened up, a valve that moved, a part that failed, or an issue on the supply side. Working through where and how the pressure dropped narrows down the cause quickly.

Search for how long PEX plumbing lasts, and one claim turns up within a minute: that plastic supply pipe breaks down in chlorinated water, sometimes with several years attached, sometimes with a warning that a PEX repipe is already on a clock.

From constant running to rocking bases, even the tiniest flaw makes a big impact on how the bathroom feels.

Two houses stand on the same street, built the same year by the same builder, with the same rooms in the same order, the same bathroom at the same far corner of the plan.

You have already run the test without quite meaning to. Every other faucet in the house — the bathroom sink, the tub, the hose bib outside — delivers a normal stream.

Shower valve installation plays a pivotal role in achieving spa-level comfort at home.

A cartridge sits on a paper towel on the counter, pulled from a faucet that would not stop dripping.

Turn the handle and water shows up right away, tracking down the base of the spout or beading along a seam near the handle.

Go up a pipe size, and the water pressure in the house goes up. That is the advice, repeated at hardware store counters and across half the search results on this subject, and it is wrong in a specific way worth knowing before anyone opens a wall.

The question usually arrives pointed in the wrong direction. " Plumber" or "handyman" is a question about people, and the thing sitting under your sink is not a person.

Soap scum that seems to regenerate overnight like a bathroom villain.

You stand there in your kitchen in Paramount, CA, staring at water pouring into the sink long after you’ve shut the handle.
