Installing a WellSeal™
- A WellSeal™ to fit over your well cap. (See “Measuring for your WellSeal”)
- Source of heat, such as a WellSeal™ HG-400 cordless heat gun, a corded heat gun or a hair dryer.
Slide the WellSeal™ over the well cap, taking care to fit it over the bolt heads.
Position it so that the text is opposite the conduit and the seal is extending approximately 1 inch above the top of the well cap.
Apply low, steady heat to shrink the WellSeal™. Start at the top of the side opposite the WellSeal™ logo. Work down and around both sides towards the logo. Continue to apply even heat until the WellSeal™ conforms to the wellhead. Be careful not to overheat, as too much heat will melt the WellSeal™, causing a hole.
