A sump pump only has one job, but it's an important one: keeping groundwater from flooding a basement or crawl space. It's also a system many homeowners never think about until the moment it fails during a heavy rain, which is exactly when you need it most. Pasco Plumbing installs new sump pump systems and maintains existing ones across Washington, where seasonal rain and groundwater make a working sump pump genuinely important home infrastructure.
We treat sump pump work with the same standard as everything else we do: a clear explanation of your system's condition, a free estimate before any work starts, and installation or repair work that accounts for what happens when the power goes out or the pump is asked to keep up with an unusually heavy storm.

Signs You Need Sump Pump Maintenance & Installation
- A sump pump that runs constantly, even when it hasn't rained recently
- A pump that doesn't turn on at all when water rises in the sump pit
- Loud grinding, rattling, or unusual noise from the pump during operation
- Visible rust or corrosion on the pump or its fittings
- A musty smell or visible dampness in the basement or crawl space
- A sump pit that's been dry for years with a pump nobody has tested
- No battery backup on a home that has experienced power outages during storms
- A pump that's more than 7-10 years old and has never been serviced
New Sump Pump Installation
Installing a sump pump correctly starts with the right pump for your situation — pit size, expected water volume, and vertical distance the water needs to travel all affect which pump size and type actually make sense. We also consider whether a battery backup system is worth adding, since the moment a sump pump is needed most is often during a storm, which is exactly when power outages are more likely.
We install the pit liner, pump, check valve, and discharge line so that water is routed well away from the foundation rather than just a few feet from the house where it can work its way right back in. Every new installation is tested by adding water to the pit and confirming the pump activates, moves water efficiently, and the check valve prevents backflow into the pit.
Maintaining A Pump You Already Have
A sump pump that sits unused for months at a time can seize up, develop a stuck float switch, or accumulate debris in the pit without anyone knowing until the day it's actually needed. Regular maintenance — testing the float switch, clearing debris from the pit, checking the check valve, and confirming the discharge line is clear — catches these issues while there's still time to fix them.
If your pump is aging or has already needed repeated repairs, we'll give you an honest read on whether continued maintenance makes sense or whether replacement is the more reliable option, particularly ahead of Washington's wetter months when the system needs to perform without warning.
Backup Power: The Detail Many Homes Are Missing
A primary sump pump that runs on household electricity does nothing during a power outage — which is often exactly when heavy rain is also causing the water table to rise. A battery backup system, or in some cases a water-powered backup pump, keeps your basement protected even when the power is out. We'll talk through whether this makes sense for your home and property.

Frequently Asked Questions
We generally recommend testing a couple of times a year, and always before the start of the rainy season, by pouring water into the pit and confirming the pump activates and drains it properly.
A standard sump pump won't run without power. A battery backup or water-powered backup system keeps the pump working during an outage, which is often when it's needed most.
Most sump pumps last around 7 to 10 years with normal use, though this varies based on how often the pump runs and the quality of the original installation.
Not usually. A pump that runs constantly may be undersized, have a stuck float switch, or be dealing with more groundwater than the system was designed for. It's worth having it evaluated.
Yes, we're available 24/7, since a failed sump pump during active flooding needs a fast response.
In many cases, yes — we can add battery backup to an existing system without replacing the primary pump, depending on your current setup.
It depends on pit condition, pump size, and whether backup power is included. We provide a free estimate based on your specific basement or crawl space.
