Sump Pumps, Crocks & Covers...
Since radon mitigations require the sump crock to be closed off air-tight, a number of critical ground-water issues need to be addressed up front. At RMES, we've worked with just about every sort of situation imaginable. We've had customers who have never had water in their sump crocks, even in heavy rain. We've also had customers who have a constant stream of ground-water running into their sump crock, as well as some who have nearly insurmountable amounts of water coming into their crocks during storms. It's critical to understand the ground-water issues you face, and address these issues with pump size, number of pumps, and even battery back-up pumps.
Additionally, each sump crock is built differently; some are deeper, some wider, and the drain tiles carrying water to the crocks are mounted at different heights within their crocks. It's imperative to have each pump switch turn on below the height of the drain tile, as these carry the gasses that have been pulled into the mitigation fan and must be expelled. RMES uses only heavy-duty, commercial-type sump pumps, along with adjustable-height vertical pump switches that can be adjusted to any height needed. The result is a highly dependable solution.
Crock tops are just as critical when water is a concern. To eliminate any guesswork, we install 1/4" unbreakable, clear polycarbonate crock tops, and seal these air-tight with clear silicone caulk. Yet theyre easy to get into if there is a need to do so; to streamline access and facilitate periodic testing of the sump switches, we install a screw-on 4" clean-out on our tops.
Other types of drainage, such as dehumidifiers, can be readily plumbed through these crock tops, if need be. Sump pumps can usually be switched out within 20 minutes if problems occur, and all parts are reusable. Total pump switch-out and crock-top re-assembly time is about 45 minutes.
