What's different about low water pressure diagnosis in Rock Hill
Low water pressure in a Rock Hill home comes from a short list of causes: a clogged aerator at a single fixture, a failing pressure-reducing valve at the main, a partially closed shutoff valve, a hidden service-line leak lowering the supply, or galvanized pipe narrowed by rust buildup inside. Each one has a different fix.
Weak pressure throughout the house is different from weak pressure at one tap, and a pressure gauge reading narrows it down in minutes. Call a licensed plumber serving Rock Hill to measure, find the actual cause, and give you a written repair price — not a guess.

Low Water Pressure Diagnosis questions from Rock Hill homeowners
What is a pressure-reducing valve and does my Rock Hill home have one?
A PRV is a bell-shaped fitting where the main line enters the house that limits street pressure to a safe range. Most homes built after about 1980 have one. When it fails, pressure drops or fluctuates throughout the house. They typically last 10 to 15 years.
Why is the water pressure only low at one faucet in my Rock Hill home?
A clogged aerator screen, a failing cartridge or a partially closed angle-stop valve under that fixture are the usual causes. Cleaning the aerator is worth trying first. If that doesn't fix it, a plumber isolates the exact restriction in one visit.
