Recommended for DIY upgraders wanting dependable, low-fuss performance.

Prep your site by shutting off the pool pump and draining lines. Match existing plumbing; use adapters for 1.5-inch ports if upgrading from 2-inch systems to avoid vibrations.

• Remove old filter sand carefully with a shop vac to reuse if fresh.
• Assemble laterals by folding them out inside the tank, then add water halfway before sand to protect them.
• Plumb with purple primer and PVC cement; test for leaks before full startup.
• Backwash 5-10 minutes initially to clear new sand sediment.

Watch pressure gauges post-install for optimal flow.

Regular backwashing keeps performance peak: run until water in sight glass clears, about 2-3 minutes weekly or when pressure rises 8-10 PSI.

• Switch to rinse after backwash to settle sand and prevent clouding.
• Drain fully for winterizing via the large sand/water port.
• Inspect O-rings yearly; lubricate for smooth valve turns.
• Avoid Amazon sand; source locally for cost savings and right grain size.

Expect 5+ years of service with basic care, far outlasting cartridges.
