The Premium Uni 5 Bag Pool Sand Filter (Black) is a heavy-duty filtration unit engineered for large residential swimming pools requiring robust, long-term performance. Its core design focuses on structural reinforcement at critical stress points to prevent common failure modes.

This product is specifically for South African pool owners, installers, and contractors managing large pool systems (approximately 60,000 to 100,000 litres) where reliability and durability are paramount. It is explicitly a PREMIUM model, differentiated from standard filters by its reinforced construction and extended 5-year tank warranty.

The tank is manufactured from UV-stabilised, corrosion-resistant polymer with a matte black finish for enhanced sun protection. Key reinforcements are applied to the mid-section seam, the multiport valve connection zone, and the lid seating band. It includes a side-mounted 6-way multiport valve with an integrated sight glass for backwash monitoring. The filter supports various media types but is sold as a tank-and-valve system; media, base, and plumbing connectors must be purchased separately.

 FAQs (Featured Snippet Style – SA Focused)

Q: What size pool is this Premium Uni 5 Bag filter for?
A: It is designed for large residential pools holding between 60,000 and 100,000 litres of water. The exact suitability depends on your specific pump size and plumbing layout.

Q: Why is this considered a premium filter compared to standard models?
A: It features reinforced construction at the tank seam, valve connection, and lid band for increased durability under pressure. It also comes with a 5-year tank warranty, which is longer than typical standard filter warranties.

Q: Does it have a pressure gauge to tell me when to backwash?
A: No. This filter uses an integrated sight glass on the multiport valve. You initiate a backwash cycle and visually monitor the wastewater in the sight glass until it runs clear.

Q: Can I use glass media instead of sand in this filter?
A: Yes. The filter is fully compatible with standard filter sand (200kg), ECO Glass (150kg), Pure Glass (160kg), or Eco Fibre (5x1kg bags). Media is sold separately.

Q: What pump size should I pair with this 5-bag filter in South Africa?
A: It is typically paired with pool pumps ranging from 0.75kW to 1.1kW. A professional installer can specify the correct pump based on your pool’s volume and plumbing.

Q: What is included in the 5-year warranty?
A: The 5-year warranty covers the polymer filter tank. The multiport valve and internal components are covered by a separate 12-month warranty.
