In Centennial homes from the 1980s, the shutoff valves under kitchen and bathroom sinks are often original equipment that has never been operated. When these valves are finally turned to address a repair or fixture replacement, they frequently fail to shut off completely or fail entirely, which complicates a simple fixture swap into a larger plumbing project. WireNut’s plumbers plan for this in older Centennial homes and come prepared to address shutoff valve failures as part of kitchen and bathroom plumbing work.

Kitchen and bath plumbing work connects naturally to broader home plumbing. Our faucet repair service handles dripping faucets and worn cartridges specifically.

Why Do Shutoff Valves Fail in Older Centennial Homes?

Shutoff valves under sinks and behind toilets in Centennial homes from the 1980s are typically compression or gate-style valves that have been in the open position continuously for 30 to 40 years. The internal seats and packing in these valves degrade over time, and the valves that have never been operated often cannot be closed fully when they are finally needed. This is a problem because a valve that will not shut off completely means you cannot isolate the fixture for repair without shutting off the main water supply to the home.

Replacing old shutoff valves with modern quarter-turn ball valves is a straightforward upgrade that gives Centennial homeowners reliable isolation capability for every fixture. WireNut can replace shutoff valves throughout the home as a single project or address them one at a time as fixture work comes up.

What Plumbing Work Is Typically Needed During a Bathroom Remodel in Centennial?

A bathroom remodel in a Centennial home typically involves moving or replacing supply lines to new fixture locations, installing new shutoff valves, updating drain rough-in to match the new fixture layout, and connecting new fixtures to existing water and drain services. In older homes where the existing supply is galvanized steel, a bathroom remodel is often the right time to repipe the supply lines to that bathroom in copper or PEX, which is the modern flexible plastic pipe that does not corrode. WireNut handles the full plumbing scope of bathroom remodels with permits and inspections included.
