Foting 16 vs 18 Inch Filter Specs
Flow Rate
The Foting 18-Inch 1 HP Sand Filter Pump delivers a maximum flow rate of 5000 GPH. This higher output allows it to circulate water more quickly, making it suitable for larger above-ground pools up to 25,000 gallons. In comparison, the Foting 16-Inch 1 HP Sand Filter Pump offers a maximum flow rate of 4500 GPH. This lower flow rate is still effective for filtering pools up to 18,000 gallons. If you have a smaller pool, the 16-inch model provides sufficient circulation. However, for larger volumes, the 18-inch unit moves water faster, reducing the time needed to achieve clear water.
Tank Capacity
Tank diameter directly impacts how much filter media you can use. The Foting 18-Inch model features a 18-inch tank diameter. This larger surface area supports more sand, which generally improves filtration efficiency and allows for longer intervals between backwashes. The Foting 16-Inch model has a 16-inch tank diameter. It holds 120 lbs of sand, which is a solid capacity for standard pools. While the 16-inch tank is adequate for its rated 18,000-gallon capacity, the 18-inch tank offers greater media volume. This extra capacity can handle heavier debris loads more effectively over time.
Valve Functions
Multiport valves control water direction for maintenance tasks. The Foting 16-Inch pump includes a 7-way valve. This provides seven distinct functions: filter, backwash, rinse, waste, recirculate, closed, and winter. The Foting 18-Inch pump is equipped with a 6-way valve. It combines filter, backwash, rinse, recirculate, waste, closed, and winter functions. Both valves offer the essential settings needed for standard pool maintenance. The 16-inch model lists one additional function in its description, potentially offering slightly more granular control for specific scenarios. For most users, both valves provide the necessary options to keep the system clean and operational.
Build Thickness
Durability depends on material quality. The Foting 18-Inch pump highlights thicker filter tanks and connecting pipes. The tank wall thickness increased from 4 mm to 5 mm, and the black pipe thickness increased from 2 mm to 3 mm. This design change aims to prevent cracking during transportation and extend service life. The Foting 16-Inch pump is described as having a high-strength, corrosion-resistant tank. It does not specify wall thickness measurements. Both units are built for above-ground use and weather resistance. The explicit mention of increased material thickness in the 18-inch model suggests a focus on structural robustness.
Pool Compatibility
Each pump is rated for a specific maximum pool size. The Foting 16-Inch pump is ideal for pools up to 18,000 gallons. This makes it a good fit for medium-sized above-ground pools. The Foting 18-Inch pump is designed for pools up to 25,000 gallons. This higher capacity rating means it can handle larger water volumes without straining the motor. If your pool is near the 18,000-gallon mark, the 16-inch model is sufficient. For pools between 18,000 and 25,000 gallons, the 18-inch model is the necessary choice to ensure proper filtration and circulation.
Choose the Right Foting Filter
Owner of a large pool up to 25,000 gallons
The 18-inch model handles pools up to 25,000 gallons. Its 5000 GPH flow rate circulates water faster than the 16-inch version. This higher capacity ensures your larger volume of water stays clear and clean with efficient filtration performance.
User wanting seven distinct valve functions
This 16-inch pump includes a 7-way valve. It offers filter, backwash, rinse, waste, recirculate, closed, and winter modes. The extra closed and winter settings provide more control over system maintenance and seasonal preparation compared to the 6-way valve option.
Pool owner under 18,000 gallons needing standard fit
The 16-inch tank is ideal for pools up to 18,000 gallons. It holds 120 lbs of sand for effective filtration. This size matches standard above-ground pools perfectly, ensuring optimal water circulation without the bulk of the larger 18-inch unit.
