Reliable Groundwater Removal

Zoeller Sump Pumps

We commonly use Zoeller sump pumps because they are designed for dependable groundwater removal in residential basement and crawl space applications.

The correct pump size depends on:

Amount of groundwater
Size of the drainage system
Vertical discharge height
Length of discharge piping
Number of connected drainage areas
Whether a secondary or backup pump is needed

The pump should be selected as part of the complete drainage system rather than based only on horsepower.

Backup Water Protection

Battery Backup Sump Pump Systems

Power outages often happen during the same storms that create the greatest demand on a sump pump.

A battery backup system can continue removing water if the main pump loses power.

Battery backup systems may provide protection during:

Power outages
Severe thunderstorms
Utility interruptions
Primary pump failure
High-water conditions

The amount of backup operating time depends on the battery, pump usage and how frequently water is entering the sump basin.

Sump Pump Backup Protection

Why Battery Backup Protection Matters

If a basement waterproofing system depends on a sump pump, losing power during a storm can leave the home without active drainage.

A backup system provides an additional level of protection by giving the homeowner a second pumping source when the primary system cannot operate normally.

For homes with significant groundwater, we may recommend:

Primary sump pump
Secondary sump pump
Battery backup system
High-water alarm

A properly planned backup system can provide an additional layer of protection when the primary sump pump cannot operate normally.

Sump Pump Replacement

Sump pumps do not last forever.

Warning signs that a sump pump may need replacement include:

Pump will not turn on

Pump runs continuously

Unusual noise

Slow water removal

Frequent cycling

Rust or deterioration

Float switch problems

Old or outdated equipment

If the pump fails, the drainage system can continue collecting water with nowhere for that water to go.

Sump Pump System Components

Sump Pump Basin Replacement

The sump basin is also an important part of the system. A proper sump basin should provide enough space for the pump to operate correctly and allow water from the perimeter drainage system to enter efficiently.

We can replace small, damaged or improperly installed sump basins and older sump systems with properly sized basins designed to work with the drainage and pumping system.

Small or inadequate sump pits

Damaged basins

Open sump pits

Improperly installed containers

Older sump systems

A properly sized basin allows the sump pump to operate correctly while providing an efficient collection point for water entering from the drainage system.

Sump Pump Discharge Components

Check Valves

A check valve prevents water that has already been pumped upward from flowing back into the sump basin when the pump shuts off.

Without a properly functioning check valve, the pump may repeatedly move the same water.

The check valve should be installed where it can function properly and remain accessible for service.

Proper Installation Matters A properly installed check valve helps keep discharged water moving in the intended direction while allowing the component to remain accessible for future service.

Sump Pump Discharge Lines

The discharge line carries water away from the sump pump and out of the home.

A discharge system may include:

Interior PVC piping

Check valve

Wall penetration

Exterior discharge piping

Underground discharge extension

Freeze protection where needed

The discharge point should be designed so water is moved away from the foundation rather than cycling back toward the basement.

Sump Pump Water Discharge

Underground Discharge Extensions

Where site conditions allow, the sump pump discharge can be extended underground to move water farther away from the foundation.

This can help reduce:

Water Pooling Near the House

Foundation Saturation

Erosion

Water Returning Toward the Basement

The layout should be based on grading, distance and a safe discharge location.

Basement Waterproofing Drainage

Sump Pumps for Basement Waterproofing Systems

A sump pump works together with the interior drainage system.

Water collected from the following areas is directed into the sump basin:

Foundation Walls

Weep Holes

Perimeter Drainage Pipe

Window Well Drains

Stairway Drains

Groundwater Beneath the Floor

The pump then removes that water from the basement.

The sump pump is an important part of the complete basement drainage system, helping remove water collected beneath and around the basement.

Crawl Space Water Management

Sump Pumps for Crawl Spaces

Sump pumps can also be installed in crawl spaces where groundwater collects beneath the home.

A crawl space sump system may be combined with:

Perimeter drainage
Encapsulation
Vapor barrier
Dehumidification
Battery backup protection

This allows groundwater and humidity to be addressed as part of one complete crawl space system.
