Sump Pump & Sewer Pump Service in Lilburn, GA

Most sump pump repairs start with the pump, because that is the part that hums, clicks or falls silent. Yet many pump problems trace back to the pit. A basin that is too small, too shallow, open to silt or cracked can wear out a perfectly good pump in a few seasons. In Lilburn basements and crawlspaces, a technician who looks at the whole pit, not only the motor, has a better chance of fixing the problem once.

What the pit is supposed to do

A sump pit is a collection point. Groundwater reaches it through drain tile under the slab, through holes in the basin wall or simply by seeping up from below, and the pump empties it once the water climbs to a set level. The pit needs enough volume that the pump runs a reasonable cycle instead of starting and stopping every few seconds, enough depth for the pump to sit below the incoming water and enough room for the switch to move freely.

Pits that are too small

Some older pits are little more than a hole lined with a short length of pipe or a plastic bucket. With so little volume, the pump empties the space in seconds and switches on and off far more often than it was designed to, which wears both the motor and the switch. A narrow pit can also pin a float against the wall so it hangs up in the on or off position. When pumps keep failing early in a small pit, enlarging the basin is often a more lasting repair than one more new pump.

Silt, gravel and an open bottom

Some pits have no bottom at all, just gravel or bare soil. Others use a perforated liner that admits water through the sides. Both designs can work, but both also let fine sand and silt wash in over time. The pump then pulls grit through its impeller, the intake screen clogs and sediment piles up around the switch. A solid-bottom basin set on a stable base, with drainage stone around it, keeps the pump out of the mud. Where replacing the basin is not practical, regular cleaning and a solid block under the pump can help, provided the switch still turns on at the right level.

Lids, cracks and settling

• No lid: leaves, toys and debris fall in and jam the float, and damp air from the pit drifts into the basement.
• A cracked basin: lets soil and stones in and can shift the pump off level.
• A settled or tilted pit: sets the switch at an angle so it sticks.
• Gaps around pipes: openings where the discharge passes through the lid let debris fall through.

Ejector basins have stricter demands

A sewage ejector basin is held to a higher standard. It is built to be watertight and gastight, with a bolted, gasketed lid, a vent and sealed openings for the inlet and discharge. A cracked or corroded ejector basin is not something to patch and forget, since sewage can escape into the soil under the slab and sewer gas into the house. Replacing one usually means breaking out the concrete around it, setting a new basin at the right depth, reconnecting the inlet from the basement fixtures and repouring the floor. Cracks or damp concrete near a basin are worth having checked, along with any drain repair the inspection points to, and broken piping farther out under the slab may call for drain excavation to reach it.

Permits for pit work in Lilburn

Lilburn's Business Services Department lists plumbing systems among the projects that need a permit and asks residents to check in before work starts. Under the city's code, even a minor repair generally skips the permit only with the planning director's approval, so a call to the department before cutting into a slab is time well spent.

Sump pit questions from Lilburn basements

How big should a sump pit be?

There is no single figure, since it depends on the inflow and the pump. Many pump makers list a minimum basin size in their instructions, and that is the place to start. Beyond that, a pit that gives the pump a steady run each cycle and has room for the chosen switch is about right; one the pump empties in a few seconds is too small.

Can a new basin go in the same spot as the old one?

Usually, if the location still makes sense. The old pit is broken out, the hole is widened or deepened as needed, and a new basin is set level with stone around it before the floor is patched. If the old spot sits under stairs or behind storage, it is worth asking whether a nearby location would be easier to service, as long as the drain tile can still reach it.

Why is there sand at the bottom of my sump pit?

Groundwater carries fine soil with it, and an open-bottom pit, a perforated liner or a crack lets that soil settle in the basin. A thin layer built up over years is normal. A layer that grows quickly, or comes back within weeks of a cleaning, means the basin is letting in too much, and a solid-bottom basin or a fabric-wrapped liner usually solves it.

Setting the pit right

When you call, mention how old the pump is and how often it has been replaced; repeat failures are a strong hint that the pit deserves attention.
