Waterbox Sock Silencer 4.0 for 4 in Filter Socks

The Waterbox Sock Silencer 4.0 is a round perforated plate with a central opening that sits in a 4 inch filter sock where the drain water enters. Spreading the falling water across the plate cuts the splashing and gurgling that a sump can make, keeping the system quieter. It is a simple add-on for Waterbox sumps that use 4 inch socks.
