With an incredible amount of (384) 3/8” perforations, the SumpZilla Sump Pump Basin allows for maximum water intake. Its rectangular design fits nicely into corners making concrete finishing and floor covering easier to install. SumpZilla is topped off with a two-piece clear lid for convenient inspection and access. Lids also feature a pre-installed airtight drain, sealed electrical cord pass-throughs, and discharge line grommets. A gasket is used to seal the basin lid and protect against water vapor, odors, and radon gas. SumpZilla fits multiple sump pumps with elbow room to spare.
