Common Problems

Stuck Shut-Off Valve

Usually discovered during an emergency -- something is leaking and the valve will not budge. Older gate valves seize after years of disuse. Fix ranges from penetrating oil and patience to full replacement.
Leaking Valve Stem

Water dripping from around the valve handle or packing nut -- packing failure, not a pipe leak. Fix is usually tightening the nut or replacing the packing, often with the water still on.
PRV Failure -- High Water Pressure

Failing PRV lets dangerously high pressure into the house. Bursts supply lines, damages appliances, causes hammer, shortens fixture life, leaks everywhere. Normal is 40-60 PSI. Above 80 is dangerous and needs immediate attention.
Pinhole Leaks in Copper

Tiny holes from the inside out due to pitting corrosion. Start as small drips or green stains. One is a repair. Multiple are a warning that the entire system may be deteriorating.
