What are water supply lines for sinks?

Water supply lines for sinks are the hot and cold lines that connect shut-off valves to faucets at kitchen, bathroom, utility, and bar sinks.

What types of sinks does this service cover?

This service covers: Kitchen sinks, Bathroom sinks, Utility and laundry sinks, Bar and prep sinks

When should sink water supply lines be replaced?

Supply lines should be replaced if they are leaking, corroded, kinked, brittle, outdated, or showing signs of wear.

Are leaking sink supply lines a common problem?

Yes. Sink supply lines are a common source of slow leaks that cause cabinet damage, mold, and flooring issues.

Do you replace both hot and cold supply lines at the same time?

Yes. Replacing both ensures balanced performance and reduces the risk of future leaks.

Are braided stainless steel supply lines better?

Yes. Braided stainless steel lines are more durable and reliable than older plastic or rubber lines.

Does this service include replacing shut-off valves?

Shut-off valves are inspected during service. Replacement is recommended if valves are seized, leaking, or outdated.
