Sewer Ejector Pump Installation
Sewer Ejector Pump Services in Marin, Sonoma & Napa County
At Ongaro & Sons, we understand that plumbing systems can be complex, and sometimes, a standard gravity-fed sewer line system just won’t cut it.
If your bathroom, laundry room, or any plumbing fixture is located below your main sewer line, a sewage ejector pump (sometimes called a sewage lift pump) might be the solution you need to keep your home functioning smoothly.
As one of the premier plumbers in the North Bay since 1932, Ongaro & Sons understands how critical a functioning sewer ejector pump is to your plumbing system. Whether you’re installing a new unit, replacing an old one, or troubleshooting an issue, our licensed plumbers bring decades of experience and the latest equipment to get the job done right.
We proudly serve Marin, Sonoma, and Napa counties with prompt, professional service.
What Is a Sewage Ejector Pump, and How Does It Work?
A sewage ejector pump is a submersible pump installed in a basin below the drain line. When wastewater enters the basin, a float switch triggers the pump to activate. The pump then grinds up waste (depending on the type of pump) and forcefully pumps the wastewater uphill to the main sewer line, preventing backups and ensuring proper drainage.
Why Your Home Needs a Sewer Ejector Pump
If your home has a basement or lower-level bathroom, chances are you’ll need a sewage ejector pump. Here’s why:
- If your home is connected to a septic system, a sewage ejector pump might be required to ensure proper wastewater flow, especially if the septic tank is located at a higher elevation than your basement.
- If your home has an older plumbing system or the pipes are undersized or in poor condition, a sewage ejector pump can help improve drainage and prevent backups.
- A sewage ejector pump helps safeguard your home by actively pumping wastewater away from lower-level fixtures, especially in flood-prone areas, preventing sewage backups and overflows in drains and toilets that could cause costly water damage and unsanitary conditions.
- Installing a sewage ejector pump can increase the value of your home, especially if it’s a common feature in your neighborhood.
- Even in North Bay homes with low water pressure, sewage ejector pumps can efficiently remove wastewater, ensuring a healthy and functional plumbing system.
Knowing that you have a reliable sewage ejector pump in place can give you peace of mind and protect your home from costly plumbing problems. If you’re unsure whether your home needs one, consult with a qualified plumber to assess your specific situation and recommend the best solution.
Sewer Ejector Pump Installation, Repair & Maintenance
You want a licensed plumber to install, repair, and maintain your home’s sewage ejector pumps. This kind of work requires specialized tools and skills, and it can also get messy pretty fast without the proper training and knowledge. There are also sizing issues and local codes to consider.
Fortunately for those living in Marin, Sonoma, and Napa counties, our sewage ejector pump experts at Ongaro & Sons are always available to help. Not only are our trained experts experienced with sewage ejector pump installation, repair, and maintenance, but they are also fully versed in all local codes and requirements.

Tips for Optimal Pump Performance
One of the best ways to keep your sewage ejector pump working properly is to be mindful of what you flush or drain. Avoid putting grease, wipes, hygiene products, or anything that doesn’t readily biodegrade down the drain, as these items can clog the system and damage the pump.
Regular maintenance by a qualified plumber can significantly extend the lifespan of your sewage ejector pump and prevent costly repairs down the road.
For homes with older or narrow pipes, or those with low water pressure, a grinder pump might be a better option. Grinder pumps pulverize waste before discharging it, reducing the risk of clogs. Our plumbers can advise you on the best type of pump for your specific needs.

What’s the difference between a sump pump and a sewer ejector pump?
