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.

The old vanity comes off the wall, and the bathroom looks unfinished in a way it never has before.

Fill a kitchen sink with water, place a stack of dishes and a pot to soak, and you are supporting a real, concentrated load in one narrow strip of the countertop.

The faucet is out of its shipping box and sitting on the counter before anyone touches a wrench.

Standing over a stained or chipped kitchen sink, most people ask the same question first: can the sink just be replaced, or does the whole counter have to come out with it?

Water is spreading across the cabinet floor under your sink, and you are standing over it with a phone in your hand.

Open the cabinet under the sink and look low along the back wall, where the two supply lines rise.

Two houses on the same block order the identical faucet. In the first kitchen, the sink has three holes across the deck, the cabinet under it is shallow and empty, and both shutoff valves turn shut and stay shut.

Three questions decide whether a faucet gets a new cartridge or gets carried out to the truck.

The handle turns. And turns. There is no click, no resistance, no point where the water stops, just the same loose bit of play every time you bring it back around, while the drip under the sink keeps its own rhythm.

You booked one job and are being told about a second one. The faucet was the reason for the call.
