Basements can provide excellent storage or even extra living space. However, they can often be damp and uninviting areas prone to flooding or groundwater intrusion. A professionally installed sump pump and drain system is a great way to keep your basement as dry as possible so you can reclaim that valuable space.

If you’re considering a sump pump for your Seattle home or need one replaced, turn to South West Plumbing, Heating, Air & Electric.

What Is a Sump Pump?

A sump pump sits at the bottom of a catch basin that collects excess groundwater from a drain system that’s installed around the perimeter or below the floor of the basement. The pump is submerged in the water, with the inlet and impeller at the bottom and the discharge lines at the top, above the motor.

When water starts filling the basin, a float switch rises with the water level until it’s high enough to activate the sump pump. The sump pump gradually removes the water from the basin, pumping it outside or into the home’s drain system until the float switch sinks low enough to shut the pump off.

Signs You Need to Replace Your Sump Pump

When your sump pump is nearing the end of its usable life, you may notice a few signs that it’s time to replace it, such as:

  • Abnormal noises: If your sump pump makes noises like grinding, screeching, or growling, it may be failing mechanically. If it buzzes, it may have an electrical problem.
  • Excess vibration: If your pump vibrates more than normal, the bearings or the motor may be in danger of failure.
  • Frequent cycling: When your pump turns on and off repeatedly, it may be having trouble pumping the water due to a damaged impeller or leaks.
  • Stuck motor: If the motor stops running or starts buzzing, the impeller may be stuck, or the motor may be failing.
  • The pump isn’t working: If the sump pump won’t turn on, but there’s power and the float switch is working, the sump pump may have failed.

Sump Pump FAQs


The cost of sump pump replacement will vary based on the size of the pump installed and the amount of plumbing and electrical work needed to connect it.

Most sump pumps last eight to 10 years with proper maintenance.

It’s best to have a professional plumber install a sump pump to ensure everything works reliably, and in many areas, a professional is required by code.

Your new sump pump should meet or exceed the specifications of the old pump, including the motor’s horsepower, the flow rate, and the lift height.

Garrett and Stephen came out and quickly and professionally replaced our 70-year-old sewer plumbing after it cracked. They worked super hard and ensured we had working plumbing each night and through the weekend. They finished and cleaned up and I would highly recommend them.

Chris was a very professional, knowledgeable, polite and patient plumber. They said he'd be here within the hour, he was here in 20 minutes. Pieces were missing from our brand new toilet to be installed, he was willing to take his lunch and allow us the time to run to Home Depot to exchange the toilet. Once we had all the parts, he installed it…
