POOL FILTER PREMIUM UNI 4 BAG BLACK (5 year Warranty)

Product Description

The Premium Uni 4 Bag Pool Sand Filter (Black) is a heavy-duty filtration system engineered for medium to large residential pools where structural integrity and long service life are critical. Its design incorporates targeted reinforcements at high-stress areas to withstand continuous pressure and operational demands.

This product is for South African pool owners and professional installers servicing pools between approximately 50,000 and 85,000 litres. It is explicitly a PREMIUM model, defined by its reinforced construction and comprehensive 5-year tank warranty, setting it apart from standard filters.

The tank is constructed from UV-stabilised, corrosion-resistant polymer with a matte black finish for superior sun protection. Reinforcements are applied to the main tank seam, the multiport valve connection point, and the lid seating band. The system includes a side-mounted six-way multiport valve featuring an integrated sight glass for backwash monitoring, replacing the need for a pressure gauge. Filter media is required but sold separately, with options for sand, glass, or fibre.

FAQs (Featured Snippet Style – SA Focused)

Q: What makes this a premium sand filter compared to a standard one?
A: It features an extra-reinforced tank seam, reinforced multiport valve connection, and a reinforced lid band. These structural enhancements are designed to prevent stress cracking and extend the filter’s lifespan under high pressure, backed by a 5-year tank warranty.

Q: What size pool is the Premium Uni 4 Bag filter designed for?
A: It is suitable for medium to large residential pools holding between 50,000 and 85,000 litres of water, depending on pump size and system configuration.

Q: How do I know when to backwash without a pressure gauge?
A: Backwash every 2-3 weeks as routine maintenance, or when you notice reduced water flow or clarity. During the backwash cycle, you monitor the integrated sight glass and continue until the water runs clear.

Q: Can I use this filter to vacuum heavy debris directly to waste?
A: Yes. The included six-way multiport valve has a ‘Waste’ setting, which allows you to bypass the filter media and send vacuumed water directly out to drain, preventing the filter from clogging.

Q: What filter media do I need to buy, and how much?
A: Media is sold separately. You will need 160kg of standard filter sand, 120kg of ECO Glass, 140kg of Pure Glass, or 4 x 1kg bags of Eco Fibre.

Q: What does the warranty cover?
A: The polymer filter tank is covered by a 5-year (60-month) warranty. The multiport valve and all internal components are covered by a separate 12-month warranty under normal residential operating conditions.
