4”-6" x 100' Drain Pipe Filter Sock

Forms a water-permeable barrier to seal against deposit build-up. Tear-resistant sock slips over pipes quickly and easily. Designed for use with 3 to 4 in. diameter pipes. Fabric can be easily cut to needed length and slipped over a pipe, similar to pulling a sock on a foot. Reduces sand and sediment deposits in a drain pipe for free-flowing drains. Reduces the need for gravel backfill. Dependable way to keep drain lines clog-free.
