Frequently Asked Questions

Q: Is this pool filter maintenance kit compatible with all Hayward pool filter models?

A: This kit is specifically designed for use with Hayward Navigator 925, Pool Vac Ultra, and Pool Vac Plus in-ground automatic suction pool cleaners and their associated filter systems. Please verify your model number against the part numbers (CX900G, ECX1322A, ECX271261) before purchasing to ensure compatibility.

Q: What does the glycerin filling in the pressure gauge do?

A: The glycerin fill inside the ECX271261 pressure gauge dampens vibrations and stabilizes the needle pointer, resulting in more accurate and consistent readings. It also protects the internal mechanism from wear caused by vibration during normal pool pump operation.

Q: How do I use the Teflon tape included in this kit?

A: Wrap the Teflon tape clockwise around the threaded fittings of the pressure gauge before installation. This creates a tight, secure seal that prevents air or water leaks, ensuring your gauge delivers accurate pressure readings right from the start.

Q: What is the warranty on this pool filter kit?

A: This kit comes with a 12-month manufacturer's limited warranty covering defective items under normal use. Accessories are covered by a 3-month warranty. Defective items must be reported and returned within the warranty period in original packaging.
