The best radon suction point in most Genesee County houses was installed decades ago by whoever put in the drain tile. Perimeter tile exists to move water, but it's also a pipe network that touches the entire footprint of your slab. And a radon system that pulls from it treats the whole house from a single connection.
How a sealed sump system works
Your open sump crock gets an airtight, gasketed lid, clear, so you can still see the pump, with sealed penetrations for the pump's discharge line and power. The radon pipe ties into the sealed crock, the fan pulls suction through the entire drain-tile loop, and soil gas that used to rise from every foot of your foundation perimeter now exits above your roof instead. Your sump pump keeps working exactly as before; a high-water alarm port and an access panel mean maintenance stays easy.
Why this beats a slab-only point (when you have tile)
A single sub-slab suction point relies on air moving through the gravel and soil under your slab, and this county's clay doesn't always cooperate. Tight soil can shrink one point's reach to a fraction of the footprint. Drain tile doesn't care about the clay: it's an open channel around the whole perimeter. Where tile exists and is intact, the sealed-sump approach routinely produces the lowest verification numbers we see, and often at the lower end of the price range because the drilling is minimal.
When it isn't the answer
Broken or silted tile, crocks that don't actually connect to a loop, and interior-only partial tile all reduce the approach's reach. We check draw during diagnostics and tell you which system your house actually wants. Sometimes the honest answer is a hybrid: sump connection plus one sub-slab point on the far side. Whatever the design, it carries the same guarantee. Below 4.0 pCi/L, designed for under 2.8, verified by test.
Frequently asked
Will sealing the sump cause water problems?
No. The lid seals air, not the pump's function. Water enters the crock underground exactly as before, the pump discharges exactly as before, and the sealed lid actually keeps humidity and the crock's smell out of your basement as a bonus.
What if my pump dies after the lid is sealed?
The lid is gasketed and removable. Pump service takes a screwdriver and five extra minutes. We label everything and leave the next plumber instructions on the lid itself.
