Frequently Asked Questions
-
Q: What is the installation process for this sand filter?
A: The filter is delivered with a pre-assembled tank and motor. You need to connect the inlet/outlet pipes (2" PVC), install the multi-port valve (optional), fill the tank with the included quartz sand, and then plug the motor into a suitable power source. A detailed manual is provided. -
Q: How often do I need to backwash the filter?
A: Backwash frequency depends on pool usage and debris load. Typically, when the pressure gauge rises 8–10 PSI above normal, it's time to backwash. For a 45m³/h filter, this could be every 1–2 weeks in the peak season. -
Q: How long does the quartz sand media last?
A: Quality quartz sand can last 3–5 years under normal conditions. When the sand becomes too dirty or fines are generated, replacement is recommended. The filter comes with enough sand for initial setup. -
Q: Can this filter be used with saltwater pools?
A: Yes, the FRP tank and motor are corrosion-resistant and suitable for saltwater systems. The optional control valve should be made of salt-resistant materials – we can provide a compatible valve upon request. -
Q: What is a Mill Test Report and why is it important?
A: A Mill Test Report is a certified document from the steel/FRP manufacturer that verifies the chemical composition, mechanical properties, and quality of the material used in the tank. It ensures the tank meets safety standards and is free from defects. -
Q: Do you offer a warranty?
A: Yes, we offer a 1-year warranty on the motor and a 3-year warranty on the FRP tank against manufacturing defects. Terms may vary by market; please consult our sales team for details. -
Q: Is the control valve included in the package?
A: The standard package includes only the filter tank, motor, and sand. The control valve (push-pull or multi-port) is optional and can be ordered separately. We recommend purchasing a compatible valve for optimal performance. -
Q: Can I get a custom voltage or plug type?
A: Yes, we offer motors with 220V/380V, 50Hz/60Hz, and various plug standards (US, EU, UK, AU, etc.). Please specify your requirements when ordering.
