We can help you put together a sump lid that fits your needs. First look over how to configure a sump lid that works with a radon mitigation system and then fill out the form at the bottom of this page with the specifics for your custom sump cover.
Not just any sump cover will work with a radon mitigation system. Consider the following design features:
This cover shows a cord seal, 2" Uniseal for the sump discharge and a removable inspection plug for access to the sump after the lid is secured and sealed.
To attach a radon vent pipe to this cover either of the two PVC coupling set ups could be used.For 4" pipe make a 4-1/2" hole in the cover. The short piece of pipe will slide into the top of the cover and held from slipping into the basin by the 5" diameter coupling. A small amount of silicone is used to seal around the coupling for an air tight fit.For 3" pipe a 3-1/2" hole is required.
Here is an installed lid. All sealing is done with silicone caulk for easier removal. The discharge pipe for the sump pump is sealed with a 1-1/2" Uniseal and a 3/4" Uniseal is used for the condensation line. The cord seal can accommodate from 1-3 cords. To allow water through the cover in the event of an emergency a one way Dranjer F-S2 valve is used. And finally a removable inspection plug (red/black) is added to allow access to the pump in case of a stuck float or other routine maintenance. A label should be fixed to the cover to note that the sump is part of the radon mitigation system.
The suction pipe for the radon fan was located over the drain tile about 20 feet away. This was closer to exit point from the basement than the sump. The radon level in this home was reduced from 64 pCi/L to 1.3 pCi/L. Very effective!!
