Hayward ECX271261 Pressure Gauge with Replacement Dial – for Pool and Spa Filters – Easy to Read

This is a replacement pressure gauge, model ECX271261, for Hayward pool and spa filtration systems. This pressure gauge is an essential monitoring instrument for proper filter operation. It connects to the internal water line via a standard 6.35 mm (1/4 inch) NPT fitting and displays the real-time operating pressure inside the filter. By observing changes in this value, the user can accurately determine the cleanliness of the filter cartridge or sand bed, and thus decide when to backwash or clean.

The pressure gauge's measuring range is designed to cover the normal operating pressure of a domestic pool filter. Its interchangeable dial can be manually adjusted using tools, allowing the user to rotate it after filter installation or cleaning to set the needle to "0" or a preset starting value.

This eliminates installation errors and ensures accurate subsequent measurements. Replacing this ECX271261 pressure gauge is necessary to restore the monitoring system's functionality when the original gauge is damaged by internal water ingress (blocking the needle), a cracked and opaque glass, or corrosion. An accurate pressure gauge can guide you to perform backwashing at the optimal time, saving water and electricity while ensuring the filter always operates at maximum efficiency.
