Have you ever turned off a water valve for a repair, only to notice a tiny leak when you turn it back on? Usually, using the valve does not suddenly create damage. Instead, it exposes wear that was already there. Let’s take a look at the reasons behind this issue and what could be causing it. This blog will cover everything you need to know.
Why Does This Happen?
A shutoff valve has seals that keep water from escaping around the moving stem. When a valve sits untouched for years, these seals can dry out, shrink, or wear down. Turning the handle moves the stem against the seal, which can reveal a weak spot. A leak around the handle or stem often points to worn packing.
Could Corrosion Be The Problem?
Yes. Older valves can develop corrosion or mineral buildup inside and around their working parts. This can make the handle harder to turn and prevent the valve from sealing properly. Older plumbing deserves extra attention as fixtures age.
Should You Keep Using A Leaking Valve?
Probably not. A small drip may look harmless, but it can become worse and cause water damage. If you cannot turn the valve easily or it will not stop the water completely, have it inspected by a plumbing professional.
How Can You Prevent Valve Problems?
Would you rather discover a bad valve during a planned inspection than during a plumbing emergency? Having older valves checked periodically can help catch worn seals, corrosion, and connection problems early. A professional can determine whether the valve needs a repair or replacement. They can also check nearby connections for signs of hidden wear.
