Properly routing the sump pump discharge ensures water is moved safely away from the foundation. Our setup includes key components to ensure long-term performance and winter protection.
Discharge Installation Overview
Start with 1.5" PVC from the house: The sump pump discharge typically exits the home using 1.5" PVC pipe.
Connect to main drainage line: This pipe should eventually connect into the larger drain system, usually tying into a main line that also handles downspout discharge.
Install freeze-protection overflow adapter: We use a specialized discharge adapter with horizontal slots. This part:
Transitions from 1.5" PVC to a 4" PVC elbow, which is compatible with our system.
Connects to 4" dual-wall pipe using a Fernco fitting.
Provides freeze/clog protection—if the main discharge line is blocked, the slots allow water to escape through a secondary path.
