I am attempting to replace the lid of my basement septic-sump - the old lid was apparently a home-made job - made of metal - and after 25 years or so - a failing rusty rotten mess. The sump pit is the usual "plastic" 18 inch diam. ~ 2 ft deep in good shape. We don't have a basement bathroom, so this sump handles 1. laundry water 2. water softener flush water 3. furnace condensate, in winter The foundation drainage sump pit is about 10 feet away. The $ 75. gas-tight lids look OK - but would involve some plumbing changes to get the holes to line-up. The modern thinking is to seal these to prevent radon gas infiltration - but I don't see how the radon gets into the plastic sump pit ? I could imagine radon leaking around the pit .. between the pit and the concrete floor - the lid doesn't seal this ... .. just thinking about making my own home-made lid - plastic barrel bottom or something ? Any thoughts or advice ? John T.
