Description
Product Overview
This precision pressure gauge is designed for Sand and D.E. (Diatomaceous Earth) pool and spa filtration systems. Featuring a clear 0-60 PSI glycerin-filled dial, this gauge provides accurate, real-time pressure readings so you know exactly when to backwash or service your filter.
Built with corrosion-resistant brass internals and a weatherproof housing, this replacement gauge withstands harsh chemical and UV exposure. Direct drop-in replacement for ECX270861 and compatible with most major pool filter brands.
Key Features
-
0-60 PSI Range: Ideal measurement range for residential and light commercial pool filter systems. Dual-scale dial with PSI and BAR markings.
-
Glycerin-Filled Dial: Liquid-filled gauge dampens needle vibration for steady, accurate readings even with pump pulsation.
-
Corrosion-Resistant Brass: Internal wetted components resist degradation from chlorinated and salt water pool chemicals.
-
Weatherproof Housing: Sealed stainless steel case with impact-resistant lens protects against rain, sun, and bumps.
-
Bottom Mount 1/4" NPT: Standard thread size compatible with Hayward, Pentair, Jandy, Sta-Rite, and most major brands.
-
Universal Compatibility: Replaces ECX270861 and fits most Sand & D.E. filters.

Why Replace Your Pool Filter Pressure Gauge?
A functioning pressure gauge is the most important diagnostic tool for your pool filtration system. When pressure rises 8-10 PSI above clean-filter baseline, it's time to backwash. A broken or fogged gauge means you're operating blind — risking reduced flow, increased energy costs, and potential filter damage.
Frequently Asked Questions
Q: How do I know when to replace my pressure gauge?
A: Replace if the needle is stuck, the dial is fogged or filled with water, readings are inconsistent, or the gauge doesn't return to zero when the pump is off. Most pool gauges last 2-4 seasons.
Q: Will this fit my pool filter?
A: If your filter has a standard 1/4" NPT threaded port and a 0-60 PSI range, this gauge will fit. Compatible with most Pentair, Hayward, Sta-Rite, and Waterway sand and D.E. filters.
Q: How do I install this pressure gauge?
A: Turn off the pump and release system pressure. Unscrew the old gauge counterclockwise. Wrap the new gauge threads with 2-3 turns of PTFE tape clockwise. Screw in hand-tight, then 1/4 turn with a wrench. Do not over-tighten.
Q: What should my normal operating pressure be?
A: Most residential pool systems operate at 10-25 PSI with a clean filter. When pressure rises 8-10 PSI above your clean-filter baseline, backwash or clean the filter. If pressure exceeds 30-35 PSI, service the system immediately.
Q: Why is this gauge glycerin-filled?
A: Glycerin dampens the internal mechanism, preventing needle flutter from pump pulsation. It also lubricates moving parts for longer life and prevents internal fogging from humidity.
Q: Can I leave this gauge installed over winter?
A: If you winterize your pool equipment, remove the gauge and store it indoors to prevent freeze damage. The glycerin fill provides some freeze protection, but prolonged sub-freezing exposure can crack the housing.
