Dranjer J-S15 retrofit sump seal, ball valve designed to be used as part of a cover for a basement sump. Not suitable where an active sump depressurization has been incorporated.
Whenever the sump is being sealed due to concerns about radon gas or odors Dranjer recomends installing model F-S2 right in the cover.
F-N2 is used in new home construction or installed as a drain for condensates wherever there is a concern about gas or oders.
F-R2 for retrofit in 2"-8" floor drain. Flexible rubber flange, brass valve. The "F series" can be used in homes where sub-slab suction has been included as a radon mitigation technique.
D-R2 for retrofit in 2"-8" floor drain seal. Flexible rubber flange, plastic valve.
SureSeal stops drain odors, radon and bugs. Simple one-piece installation; press fit. Available in 2.0", 3.0" 3.5" and 4.0".
