3-Inch Weep Hole Filter with Check Valve Product Description


- The 3-Inch weep hole filter with check valve prevents wall failure or movement by relieving hydrostatic water pressure behind structures like concrete seawalls, steel sheet piling, MSE retaining walls, and bridge abutments. Its efficient drainage system helps avoid costly repairs while ensuring long-term structural stability.
- Featuring a UV-protected vulcanized thermoplastic backflow prevention valve, this unit prevents reverse water flow, adding an extra layer of reliability to your drainage system.
- The 3-inch diameter with check valve geocomposite wick system offers a 17.44 in² filter fabric surface area, ensuring efficient water flow and drainage. Unlike traditional systems, the maintainable design allows quick cartridge cleaning or replacement, extending the lifespan of the drainage system.

Frequently Asked Questions
What is the primary use of the JF3SSCVLV?
The JF3SSCVLV is primarily used for maintaining drainage and preventing clogging in earth retention systems, especially where soil erosion poses a risk. Its integrated check valve adds extra protection by preventing backflow.
How does the check valve improve performance?
The check valve in the JF3SSCVLV prevents reverse water flow, which minimizes the risk of soil contamination and structural damage caused by water pressure buildup behind retaining walls.
What materials is the JF3SSCVLV made from?
This unit is constructed from stainless steel and high-durability plastic, ensuring resistance to corrosion and wear in harsh environmental conditions.
Can the JF3SSCVLV be used in marine environments?
Yes, the corrosion-resistant materials make it ideal for marine applications where exposure to saltwater is a concern.
How often should maintenance be performed on the JF3SSCVLV?
Inspections should occur quarterly in most conditions, but maintenance intervals may vary depending on soil and water conditions. The maintainable filter allows for easy cleaning when debris builds up.
