Wayne Water Systems WST33 Submersible Sump Pump 1/3 Hp

Product Description

The WAYNE WATER SYSTEMS WST33 is a reinforced thermoplastic submersible sump pump rated at 1/3 HP and 115 volts. It delivers up to 2500 gallons per hour at 0 feet of head, making it a reliable choice for residential sump pit applications. The top suction design draws water from above the base, which helps filter debris and reduces clogging caused by sediment that settles at the bottom of the pit. A piggyback tether float switch allows both automatic and manual operation without any wiring changes. Licensed plumbers and HVAC service technicians commonly install this pump during basement waterproofing and drainage system work.

The WST33 is intended for residential sump pits where dependable water removal is required during heavy rain or groundwater intrusion events. The 1-1/2 inch NPT discharge connection integrates into standard residential drainage piping without requiring additional plumbing modifications. The reinforced thermoplastic base and housing resist corrosion in wet pit environments. Its straightforward design suits both new installations and direct pump replacements in existing sump systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified contractor following local plumbing codes. Disconnect power to the sump pit circuit at the breaker panel before removing or installing the pump. The piggyback float switch plug connects to a standard grounded outlet, allowing the float to control the pump automatically while the manual plug bypasses the float for direct operation. Verify that the discharge line check valve and piping are intact and properly sized before returning the system to service.
