Shore-Tech 40 Gallon Big Foot Filter with Filter Matting
The 40 Gallon Big Foot Filter uses a 2″ threaded check valve and 2″ bulk-filter matting. It captures small debris such as algae and other particulates to protect irrigation pumps and sprinkler heads. The unit’s 12″ outside screen and 6″ inside screen support robust filtration, while the reusable matting minimizes ongoing costs. Constructed from heavy-duty PVC for durability in pond or lake settings.
Rusco 1-1/2″ Spin Down Separator
This spin-down sediment filter operates at up to 50 GPM and is designed to trap sand and debris before they reach the irrigation system. The clear body allows visual inspection, and the unit is straightforward to flush and maintain. It fits standard potable water lines and is compatible with common well and lake applications. A compact option for smaller to medium irrigation setups.
Shore-Tech 40 Gallon Big Foot Filter with Check Valve
The 40 Gallon filtration system features a 2″ threaded suction connection and 2″ bulk-filter matting. It is designed to trap small debris like algae, supporting longer pump life and cleaner irrigation water. The system’s dual-screen arrangement (12″ outside and 6″ inside) enhances debris capture while remaining easy to service and replace. Suitable for lake and pond irrigation setups with moderate flow needs.
Shore-Tech 80 Gallon Big Foot Filter
The 80 Gallon model provides higher capacity for larger irrigation systems, with a 2″ threaded suction connection and dual filtration surfaces (12″ outside screen and 6″ inside screen). Reusable bulk-filter matting is included to trap small debris, algae, and similar particulates. Its heavy-duty PVC construction is designed for steady performance in demanding lake environments.
Shore-Tech 80 Gallon Big Foot with Matting (Matting)
This 80 Gallon filter comes with 2″ thick reusable, replaceable bulk-filter matting. It effectively captures debris such as algae and other particulates, helping protect irrigation components. The combination of a 12″ outside screen and a 6″ inside screen provides robust filtration for lake or pond water, with a straightforward maintenance routine for busy irrigation seasons.
Merrill MFG 1″ 100 Mesh Spin Down
This spin-down filter uses a 1″ pipe size with a clear body, allowing users to see sediment buildup and flush as needed. It handles 1-20 GPM and operates up to 150 PSI. It is suitable for well or irrigation pump systems where quick visibility and simple maintenance are priorities, providing reliable protection for downstream plumbing and sprinklers.
Buying Guide: Key Considerations for Lake Irrigation Filtration
Filtration capacity matters. Choose a unit that matches your lake size and irrigation flow. Larger bodies of water and higher-demand systems benefit from 60–80 GPM or more, while smaller systems can perform well with 40–50 GPM options.
Filtration method should align with debris type. Bulk-filter matting excels at algae and fine particulates, while spin-down screens are effective for sand and sediment. Some setups combine both approaches for comprehensive protection.
Durability and materials are critical in aquatic environments. Look for heavy-duty PVC or corrosion-resistant components, and ensure seals and valves are designed for continuous outdoor use and seasonal cycling.
Maintenance practicality influences long-term performance. Reusable matting and visible-filter designs facilitate easy cleaning and flush routines. Consider how easily parts can be replaced or upgraded as debris loads change over time.
System compatibility matters. Verify thread sizes (2″ is common in pond systems) and ensure the chosen filter interfaces with your existing pumps, fittings, and irrigation controllers. A modular approach allows incremental capacity increases if needed.
