Professional Valve Services in Lubbock
Valves are the unsung heroes of your plumbing system — they control the flow and pressure of water throughout your home, and they give you the ability to shut off water quickly in an emergency. A faulty valve can lead to leaks, uncontrolled water pressure, or the inability to stop water flow when a pipe bursts or a fixture fails. Cotton City Plumbing provides expert valve installation, repair, and replacement services to homeowners throughout Lubbock, TX and the surrounding West Texas communities. One of the most important valves in your home is the main water shut-off. This is the valve that stops all water flow into your house — and in a plumbing emergency, knowing where it is and being able to turn it off quickly can be the difference between a minor repair and thousands of dollars in water damage. Many older Lubbock homes have original gate valves on the main shut-off that have seized up from years of mineral buildup and disuse. We strongly recommend replacing seized gate valves with modern ball valves, which provide a reliable full shutoff with a quarter-turn and are far less likely to fail when you need them. Pressure Reducing Valves (PRVs) are another critical component that many Lubbock homeowners don't think about until something goes wrong. Lubbock's municipal water supply can deliver pressure well above 80 psi in some areas — and sustained high pressure is one of the most common causes of premature pipe failure, water heater damage, and fixture wear. A properly functioning PRV reduces incoming pressure to a safe 50–70 psi range, protecting your entire plumbing system. If your PRV has failed, you may notice banging pipes, dripping faucets, or a water heater that's constantly triggering its pressure relief valve. Angle stops — the small shut-off valves under your sinks and behind your toilets — are another common failure point in Lubbock homes. These valves are often original to the house and have never been turned off. In hard water, the packing inside these valves corrodes and the valve body can crack when you try to close it. We recommend replacing old angle stops proactively, especially if you're having other plumbing work done that requires shutting them off. Cotton City Plumbing is a locally owned, faith-based plumbing company licensed under Master Plumber M-44446. We serve all of Lubbock and surrounding communities including Wolfforth, Shallowater, Idalou, Slaton, and Levelland.
