The STS pit & Pump Kit is ideal for crawl spaces for either a new installation or as a secondary back-up system.. The kit includes a heavy duty construction pre-formed pit with bolt down and gasket sealed lid, 2500 GPH ( @ 5 ft. high rise ) cast iron pump, rubber grommets to seal discharge & vent pipes, solid cap, vented cap, clear check valve, drain fabric ( to wrap pit ) and hardware. This pit can be used with either a drain tile or weep system. To use with a drain tile system, cut out holes for drain tile to fit into pit. To use in a weep system drill random holes all around the pit and wrap the pit with drain fabric. See step by step instructions for more information on installation.
