Grinder Pump FAQs
Why are grinder pumps needed in some areas?
With wastewater utilities throughout the county, including BCSS, there are gravity systems and pressure systems. Some areas aren’t suitable for gravity systems, so a low-pressure system is implemented. The choice is usually made when roads and subdivisions are developed, and then the utilities provide service and typically maintain the main system infrastructures. When low-pressure systems are installed, each home or building that is connected within that service territory requires a grinder pump and pressure pushes wastewater to the main line, even if the land from home/building to main road slopes downward.
What is a grinder pump?
A grinder pump is a pump unit located on a property where the wastewater drains from a house/ building through a main plumbing line that is connected to the pump. When the pump is full, it grinds the wastewater up and pumps it through an underground pipe to the main sewer line in the public street. There are various types of grinder pumps and lift stations, and the standard grinder pump that BCSS installs is usually four feet deep and approximately two feet in diameter. Grinder pumps are typically buried underground with the lid, its vent and the corresponding panel box above ground.
Why does BCSS require specific grinder pumps on its system?
The low-pressure systems within our service territory have been designed to meet strict specifications and require certain types of pumps to function properly. If BCSS does not provide and/ or install a pump, customers must purchase and have installed any progressive cavity, sometimes called a semi-positive displacement pump.
How long will a new (installed present day) grinder pump last?
10 years is the average life of a dual seal grinder pump. They are many factors that effect that a pump’s life, such as mechanical and electrical design, use, abuse, and acts of God.
What is the warranty on a grinder pump BCSS installs?
The pump is provided with a one year manufacturer’s warranty which covers defects in material and workmanship. These defects typically happen within the first year.
Do you offer an extended warranty?
The pumps that we install include a manufacturer’s defect warranty, and we do not offer nor does the manufacturer offer an extended warranty. This is mainly because manufacturer defects should be obvious within the first year of the grinder pump’s use, and additional repairs after a year are usually due to misuse. Warranty covers only defects in material and workmanship.
What is the difference in the new Keen pump compared to the last E/One pump BCSS installed?
- Dual oil lubricated mechanical seals versus the E-1 single seal
- Field serviceable panel mounted capacitors versus the E-1 internal capacitor
- Field serviceable level sensors versus internal pressure switches
- For our customers’ convenience, BCSS will continue to service existing E-one pumps on our system for as long as needed.
What happens if my grinder pump requires service, or there is a power outage? Is there an alarm?
There is an audible and/or lighted alarm on your house near the pump that will alert you that service is needed. Contact us for service at (251) 971-3022 if you’re a current customer and the alarm goes off for over 15 minutes. In the event of a power outage, the latest Keen pump that BCSS uses holds approximately 100 gallons, providing ample storage capacity.
Since dishwashers and washing machines aren’t running, that is usually more than enough for flushing toilets during the outage. With any type of sewer service, it is recommended to limit water usage.
There are generator transfer switches available for grinder pumps. If you are interested in one, please contact an electrician to discuss this option.
Is there anything I can’t put down the drain?
The wastewater system and grinder pump will handle all typical household wastewater. However, you should not allow unsuitable materials, such as grease, wipes and rags to enter the drains. We can send you a complete list of items, or you view it at baldwincountysewer.com/systemcare. Most or all of these items shouldn’t enter gravity sewer service lines or septic systems either.
Do grinder pumps require much maintenance?
No. Like other appliances in your home, grinder pumps require very low preventive maintenance. We recommend that you squeeze one cup of dish soap down the kitchen sink once a month and also hose out your pump every year (if it is the newer type pump, like the one pictured here). The best thing you can do to maintain your system & pump is to keep unsuitable items out of the drains. You can view all system care suggestions here.
Is a grinder pump noisy?
A newly installed grinder pump may make some a short sound when it turns on. A pump should not be so loud that it is disruptive, and one sound when it turns on does not mean anything is wrong with the pump. If you are concerned about your pump making a sound or have any questions regarding this, please contact us to discuss it.
Do I need to do anything special to the system if I am gone for long periods of time?
No mechanical preparations are necessary. Before any property is unoccupied for longer than 1 month, we suggest you fill up the bathtub and drain it to flush the pump.
Does the grinder pump emit any unpleasant odors?
No. Since the pump will run occasionally to remove wastewater from the basin, there is no odor.
How much does the pump cost to run (power)?
Very little as the pump usually only runs a few times a day.
What are suggestions when there is severe weather?
- When power is out, limit flushing toilets and running water in faucets.
- If your property could flood and you own a grinder pump, turn off switch for grinder pump in the main breaker box or in pump’s panel box prior to heavy rain. Be sure to turn it back on once flooding subsides.
