Pump Services Available
We service a full range of pump systems, including:
Booster Pumps
Low water pressure can be more than just a nuisance, it can disrupt your daily routine. If you experience weak flow from your fixtures, especially in multi-story homes or properties on hillsides, a booster pump can make a big difference.
Our team installs and services booster pumps that enhance water pressure from your main supply, ensuring consistent flow throughout your home. We’ll help you select the right system for your household needs and plumbing layout, and we’re available for repairs and annual maintenance to extend the life of your pump.
Common booster pump issues we address:
- Fluctuating or low water pressure
- Loud or vibrating pump noises
- Short cycling or frequent shutoffs
Recirculating Pumps
Tired of waiting for hot water to reach your shower or sink? A recirculating pump delivers instant hot water by continuously circulating it through your pipes, minimizing waste and saving you time.
Ongaro & Sons installs high-efficiency recirculation systems that work with your existing water heater, including tankless models. These systems are a great addition for large households or anyone looking to conserve water and improve convenience.
Benefits of a recirculating pump include:
- Reduced water waste
- Faster hot water delivery
- Lower energy bills with timer or sensor control options
Sewer Ejector Pumps
Homes with bathrooms or laundry rooms located below the main sewer line (such as in basements or lower levels) require a sewer ejector pump to move wastewater uphill and into the municipal system or septic tank.
Our experienced plumbers provide complete sewer ejector pump services, including installation, repair, and replacement. We also troubleshoot common issues such as clogged discharge lines, stuck float switches, or pump motor failures.
Signs your sewer ejector pump may need service:
- Foul odors from basement drains
- Gurgling toilets or slow drainage
- Frequent system cycling or alarms

Sump Pumps
Heavy rains, high groundwater, or poor drainage can lead to basement flooding or moisture buildup. A sump pump is your first line of defense against water damage in vulnerable areas of your home.
We install and maintain sump pumps designed to activate automatically when water levels rise, directing excess water away from your home’s foundation. Our team also offers battery backup systems to keep your pump working even during power outages.
We provide the following sump pump services:
- Submersible and pedestal sump pump installation
- Battery backups and high-water alarms
- Maintenance, testing, and repairs

Why Ongaro & Sons for Pump Services
Pump work has its own classification too, which is not something most plumbing contractors can say.
Schedule Service →C-61/D21 machinery and pumps
Ongaro & Sons holds the limited specialty classification for machinery and pumps alongside C-36. Pump work is squarely inside our licence.
Sized on head and flow, not on horsepower
An oversized pump cycles and fails early. Sizing is a calculation against the actual lift and run.
Controls and float arrangement done properly
Most pump callouts are control failures rather than pump failures.
Backup and alarm considered where failure floods something
For sump and ejector applications, what happens during a power cut is part of the design.
A classification most plumbers do not hold
C-61/D21 covers machinery and pumps specifically. It is on our licence, so pump work is not being done under a general plumbing ticket.

Read MoreFrequently Asked Questions
Can a recirculating pump help me save water?
Yes, by reducing the wait time for hot water, you waste less water down the drain.
How do I know if my ejector pump is failing?
Signs include foul odors, slow drains, or unusual noises from the pit.
How often should I test my sump pump?
Test it every few months and especially before the rainy season. Replace backup batteries annually if installed.
How often should pumps be serviced?
At least once a year, or more frequently for high-use systems like sump pumps.
What’s the difference between a sump pump and a sewer ejector pump?
A sump pump removes groundwater from basements or crawlspaces, helping prevent flooding. A sewer ejector pump handles wastewater from lower-level bathrooms or laundry rooms and pushes it up to the main sewer line. Both are vital for homes below grade level.
