Basement Draining & Sump Pump Systems
Stop water damage before it starts. We size and ship automatic submersible sump pumps, sewage/effluent ejectors, and self‑priming trash pumps for emergency dewatering and permanent basement systems—backed by fast stock in CA, WA, and AZ.
Which Pumps Solve Basement Flooding?
| Problem / Requirement | Best Technology | Recommended Brands | Notes |
|---|---|---|---|
| Groundwater seepage / rain events | Submersible sump (automatic float or smart switch) | Goulds, Grundfos | Quiet, compact; choose head by static lift + friction |
| Stringy debris / rags in the pit | Submersible sewage or grinder | BJM, Goulds | 2″ solids handling; grinder cuts wipes/rags for ejector lines |
| Lift to municipal sewer / overhead main | Effluent/sewage ejector package | Goulds, BJM | Sealed basin with check valve & high‑level alarm |
| Long suction runs / above‑grade service | Self‑priming trash pump (surface‑mounted) | Gorman‑Rupp | Easy service without pulling a submersible; solids‑tolerant |
| Portable dewatering during construction | Contractor submersible or AODD | BJM, Yamada | Run‑dry capable options; air‑driven for haz‑areas |
| Power outages during storms | Battery or generator backup system | Goulds, Grundfos | Automatic transfer; independent DC pump or inverter |

How We Engineer Basement Sump Systems
- Total Dynamic Head = static lift + friction loss at design flow; we size to your worst‑case rain rate.
- Solids & debris dictate sump screen, impeller style, and whether you need grinder vs. sewage.
- Duty cycle & run time choose continuous‑duty motors and thermal protection to prevent overheating.
- Materials (cast iron, 304/316 SS, elastomers) matched to groundwater, laundry/greywater, or light chemicals.
- Controls—dual floats or level sensors, high‑level alarm, check valves, and quiet‑check for backflow slam.
- Redundancy—duplex duty/standby pits and battery/generator backup for high‑risk sites.

Basement Draining FAQs
How do I size a sump pump for my basement?
Estimate peak inflow in GPM during storms, then calculate TDH = static lift + friction loss at that flow. Choose a pump curve that delivers your GPM at TDH with 10–15% margin.
What’s the difference between sump, effluent, and sewage/grinder pumps?
Sump = relatively clean groundwater. Effluent handles small solids. Sewage/grinder handles larger solids or macerates rags for long ejector lines.
Do I need a backup power system?
If outages and storms coincide in your area, yes. We recommend a DC backup pump or an inverter/generator with automatic transfer plus a high‑level alarm.
How deep should my sump pit be?
Deep enough to prevent rapid short‑cycling and to hold surge volume. Many commercial pits are 24–36″ diameter and 24–48″ deep; we’ll size to your inflow and pump cycle targets.
