Sump Pump Installation, Repair & Replacement in Tacoma, WA
Sump pump installation, repair, replacement and battery backup for crawl spaces and basements across Tacoma, Puyallup and Pierce County, set up before the November rains rather than during them.
Sump Pump Service for the South Sound’s Wet Season
From November into March the ground around a Pierce County house stays close to saturated for weeks at a time, and a crawl space or basement at the bottom of a slope, near the Puyallup River, or beside one of Lakewood’s lakes collects water it has no way to shed. A sump system gives that water somewhere to go: a basin at the low point, a pump sized to the inflow, a rigid discharge with a check valve, and a line that carries the water well away from the foundation and never into the sanitary sewer.
One install we point to was in Summit View, on the west side of Puyallup’s South Hill, in September 2025. Jerry dug the basin pit in the crawl space, ran about twenty-five feet of inch-and-a-half ABS from the pit to the discharge point, set the pump, and filled the basin with water to prove it switched on and emptied the way it should. The homeowner had just had a new vapor barrier laid, so he checked that too while he was under the house. It all went in before the rains, which is the right order.
Where a home is on septic, or has fixtures below the sewer line, the pump in the ground is a different animal: a sewage ejector or septic effluent pump in a sealed, vented basin. We replace those too, like a failed ejector pump in a septic riser in Gig Harbor this summer, and the first thing we do on any pump call is confirm which kind you have.

Signs Your Sump Pump Is Failing
Catching these before the next storm is what prevents the water damage.
Runs Constantly
A pump that never shuts off, or keeps running after the basin is empty, is fighting a stuck float, a failed check valve or more water than it was sized for.
Rapid Cycling
A pump that switches on and off in quick bursts usually has an undersized basin or a float switch set too close to the pump, and it wears out fast that way.
Grinding or Rattling
Debris in the impeller or a failing motor bearing makes itself heard, and neither gets better on its own.
Rust or Corrosion
Visible corrosion on the pump housing, the basin or the discharge connections means water is getting where it should not, and the pump is on borrowed time.
Fails to Activate
The basin fills and nothing happens. Most often the float is stuck or the outlet has lost power; sometimes the switch or the motor is finished.
Over Seven Years Old
Age alone is reason to test a pump properly before the wet season arrives, and to think about a battery backup if the house has never had one.
What We Install, Replace and Service
The pieces of a system that actually keeps water out.
Installation & Replacement
New systems and failed-unit replacement: correct sizing, a sealed basin, a rigid discharge line and a check valve, installed to code and tested with water before we leave.
Battery Backup
A backup keeps the pump running when a storm takes the power out, which is exactly when the basin fills fastest. We size the battery to the pump and show you how to test it.
Maintenance & Repair
An autumn check and a straight repair when something fails: float switch, check valve, discharge line and backup all tested before the next storm, with the price approved first.
Sewage Ejector and Septic Effluent Pumps
For fixtures below the sewer line and for homes on septic, a sealed, vented pump basin does the lifting. We replace failed ejector and effluent pumps and confirm which kind of pump a house actually has before quoting.
Where Pierce County Homes Need a Sump Pump
The water table decides it, and these are the places it decides it most often.
The Puyallup River Floodplain and Rivergrove
Low ground near the river in Puyallup sits on saturated soil through the winter, and crawl spaces there flood without a basement in sight. A crawl-space sump with a rigid discharge is the normal answer.
Lakewood’s Lake Neighborhoods
Around American Lake, Steilacoom Lake, Lake City and Phillips Lake in Lakewood, the water table is high enough that a basement or crawl space needs help every wet season.
Tacoma Crawl Spaces on the Hills and the South Side
Homes on the slopes above Ruston Way and the crawl-space ramblers of Tacoma’s south side collect groundwater at the low corner. Tacoma runs separate storm and sanitary sewers, and the City asks that sumps discharge to the storm drainage system, never the sanitary side.
Our Sump Pump Process
How an installation is planned rather than just dropped in.
Drainage Assessment
We look at where the water comes from, how high it gets and where it can be sent, then pick the low spot for the basin.
Sizing & Selection
The pump is sized to the water the pit actually sees, submersible or pedestal, with a check valve so the discharge cannot fall back and start the pump again.
Code-Compliant Install
Basin set and sealed, discharge routed rigid and away from the foundation, and a safe electrical connection, with a battery backup where losing the space would matter.
Water Test and the Autumn Check
Every install is filled and watched through a full cycle before we leave, and we recommend a test every October, before the first November storm proves the point for you.

Sump Pump Questions
Lifespan, backups, discharge lines and why a pump runs non-stop.
Seven to ten years for most units. A pump in a high water table cycles thousands of times a winter and wears sooner, and a pump that has sat dry for years can seize the first time it is needed. Age alone is worth acting on before a storm proves the point, which is why we suggest an October test.
Far enough from the foundation that the water does not soak back toward the basin, onto ground or into a storm drain that can take it, and never into a sanitary sewer or a floor drain. In Tacoma the City is explicit that sumps belong on the storm side. Getting this wrong is why some pumps run forever.
