The Premium Uni 2 Bag Black Pool Sand Filter is a robust filtration unit engineered for long-term durability in small to medium residential pools. Its design prioritises structural reinforcement at key stress points to ensure longevity under continuous operating pressure.

This product is for South African pool owners and installers requiring a reliable, heavy-duty filter for pools up to 40,000 litres. It is explicitly a PREMIUM model, distinguished from standard filters by its reinforced construction and extended 5-year tank warranty.

The tank is made from UV-stabilised, corrosion-resistant polymer with a matte black finish for enhanced sun protection. It features reinforced sections at the central seam, multiport valve connection, and upper lid band. The unit includes a side-mounted 6-way multiport valve with an integrated sight glass for visual backwash monitoring. Filter media is required but sold separately, with compatibility for sand, glass, or fibre options.

4️⃣ FAQs (Featured Snippet Style – SA Focused)
Q: What size pool is the Premium Uni 2 Bag filter for?
A: It is best suited for small to medium residential pools holding between 15,000 and 40,000 litres. Exact sizing depends on your pump, plumbing, and chosen filter media.

Q: Why does this filter have no pressure gauge?
A: It uses a sight glass on the multiport valve instead. You visually confirm backwash is complete when the water in the sight glass runs clear, which many find more intuitive than monitoring pressure.

Q: How often should I backwash this filter in South Africa?
A: Typically every 2-3 weeks, depending on debris load (like summer leaves or pollen), bather load, and weather conditions. Backwash until the sight glass water is clear, which usually takes 1-3 minutes, followed by a 15-30 second rinse cycle.

Q: What is the benefit of the reinforced construction?
A: The reinforced central seam, valve connection, and lid band are designed to prevent stress cracking and tank failure, significantly extending the filter’s service life under constant pump pressure.

Q: Can I use glass media, and how much do I need?
A: Yes, it’s fully compatible with ECO Glass (60kg) or Pure Glass (60kg), which can improve filtration. Standard sand requires 80kg. Media is purchased separately.

Q: What warranty does this premium filter come with?
A: It includes a 5-year (60-month) warranty on the polymer filter tank. The multiport valve and internal components are covered by a separate 12-month warranty under normal residential use.
