Snellville homes

Snellville is an established southern Gwinnett suburb on US 78 with a small-town feel. Census survey figures put the median home at 1991, with about 30% built before 1980, so many houses have pumps that are decades old or were added after construction. Gwinnett County Department of Water Resources provides water and sewer; it maintains the main and meter, and owners are responsible for everything on their side, including the entire sewer lateral. That makes the sump system entirely the owner's, and it means groundwater shouldn't be pumped into that lateral. Many older Snellville homes have a pump that drains into a laundry sink or ends right at the foundation, where the water soaks back toward the pit. A plumber can reroute it to the yard. Gwinnett water is soft and chlorinated, so mineral buildup isn't usually the cause of a stuck float; silt and debris in the basin are more likely.

Steps to take right now

Turn off the pump's breaker if water is near the outlet or cord.
With power off, check the float and free it if it's stuck.
Restore power. If you hear humming but no water moves, shut it off again.
Check the outdoor outlet for a clog or a disconnected pipe.
Move belongings off the floor near the pit.
Note whether the pump has been running more than usual in the past few days.
If water keeps rising, call for a plumber.

Sump Pumps questions in Snellville

Why does my sump pump run when it hasn't rained?

Groundwater can seep in for days after rain. If the pump runs in a long dry spell, look for a leaking supply line, irrigation runoff or a check valve letting water fall back.

Where should the water end up once the pump pushes it outside?

Onto the yard where it drains away from the foundation. Not into the sewer lateral, which Gwinnett County treats as the owner's.

Could the water under my house be a plumbing leak rather than groundwater?

Sometimes. A leak on the line between the Gwinnett meter and the house can look like seepage. A plumber can check before you upsize the pump.

Do I need a permit to replace or add a sump pump?

A straight pump swap is often treated as a repair. Snellville issues its own permits and inspections, so if piping changes, ask the plumber to confirm.
