What type of shutoff valve is best?

Quarter-turn ball valves are the most reliable. They provide a positive shutoff and are less likely to seize than multi-turn gate valves. Replace old gate valves with ball valves when possible.

How often should shutoff valves be exercised?

Turn each valve off and on once or twice a year to prevent seizing. This ensures they will work when you need them in an emergency.
