ARD was hired to reduce the radon levels in another finished basement on a sump pit. The sump pit had a water backup sump pump so we were able to install a high rise cover to properly air seal the sump without impeding the operation of the backup pump. Routed piping outside and installed a sound reducing muffler to make the system silent from the inside. Client was thrilled with the entire install and of course the radon levels were brought down to a minimum!
