Pool plumbing can take confusion to new heights. If your pool was built before the mid-eighties, it’s probably time to modernize. The Jandy Valve revolutionized pool plumbing with its three-way butterfly valve that allows for consolidation of several leaky, hard to turn gate valves into one simple operation. This reduces the number of valves and prevents pipes from going in every direction. Eventually, every pool needs to have the suction side (before pump) valves and the pressure side (after the filter) valves replaced—at least every 20 years.
