Product Details
Water Fill Box (WFB) Product Description
The Water Fill Box (WFB) is a specialized housing designed to neatly and securely install an automatic water fill valve into your pond, Just-A-Falls system, or formal pool. It provides an excellent, discreet alternative for water features that do not utilize a traditional skimmer filter, allowing you to maintain perfect water levels without visible equipment.
CRITICAL INSTALLATION WARNING: This box features integrated water slits/grates on the side to allow water to flow freely from your pond or basin directly into the box. It is NOT a sealed container. It is designed exclusively for submerged or inline water feature environments where water levels equalize naturally. Do not attempt to use this as a dry, sealed enclosure or in standalone external applications where a completely watertight box is required.
