Fixing Your Sink
Whether kitchen or bathroom, fixing a sink can be straightforward or it can be a nightmare. Much depends on the condition of the valves and hoses leading to them.
In most cases do-it-yourselfers can shut off the water valves under the sink with a few clockwise twists. But if those valves are old and have never been turned since they were installed they can break, causing a leak.
Be prepared by having a partner stand near the main shutoff valve with a walkie-talkie ready to turn off the water to the whole house.
