You’ll find them across dozens of major brands because they are reliable, affordable, and built around standardized designs. But that same standardization creates confusion when it’s time to replace one. Especially internationally. And especially when trying to determine horsepower versus amperage. This guide breaks down: • How LX pump numbers actually work• Why brand numbers don’t mean it&rs …

If you are outside the United States and replacing a diverter valve, cap, or handle, the most important thing to understand is this: The “1-inch” and “2-inch” rating has NOTHING to do with the size of the cap you see on top of your spa.
