Product Specifications
Technical specifications for our Rainstopper inserts are available for download below, covering materials, design details, gasket and relief valve performance, installation guidance, and warranty terms.
Acceptance & Storage
Proper storage helps ensure a long service life. Long-term exposure to UV rays can deteriorate the gasket, so stored units should be protected from direct sunlight. Rainstopper leaving shrink-wrapped units on pallets if stored outdoors or storing unpackaged units indoors away from UV exposure. HDPE units should follow the same basic handling guidelines and be stored on flat, stable pallets.
Installation Instructions
To install the Rainstopper, remove the manhole lid. Clean all dirt and debris from the manhole frame. Add grease and twist the unit 90 degrees when setting it down, then seat the Rainstopper in the manhole frame rim. Replace the manhole lid and ensure it sits flush with the frame to prevent tripping hazards. Once installed, no maintenance is required.
