The owner's guide contains helpful information about your grinder pump: how it works, items that should not be emptied down the drain, and what to do if the alarm sounds. There is a place to write down the phone number for service. If you don't already know who to call, call our Service Link (in the USA) at 1-866-539-9803 or use the Distributor Locator.

Q: What do I need to know about my grinder pump?
A: All of the wastewater in your home from toilets, showers, dishwashers, sinks, etc. empties into the grinder pump station. When the water in the tank reaches a certain level, the pump will turn on automatically and pump the wastewater to the sewer system. Most of the time, you won't even notice the pump running; it produces about the same level of noise as a washing machine and usually runs for only a few minutes.

Take care not to dump oil, grease, paint, strong chemicals, sand, kitty litter, etc. down your drain. Feminine products and personal/cleaning wipes should be disposed of in a garbage can. These items should not be introduced into any sewer or septic system; they can damage or cause premature problems (parts wearing out) with your pump, or build up in the tank and prevent your pump from working properly.

Q: What if the alarm goes off?
A: If the alarm sounds on your grinder pump, push the Silence button located on the outside of the panel box. If your grinder pump is in your basement and doesn’t have a separate panel box, remove the gray cover and push the Silence button. If the red light does not turn off after an hour or so, you should call for service. Look for a phone number on the alarm panel, or call the Service Link at 1-866-539-9803.

Q: Who do I call for service and repair?
A: E/One recommends that you call an E/One authorized distributor or service center for service and repair. They are trained by Environment One and knowledgeable about our pumps.

First, look on your alarm panel for a service sticker with a phone number (confirm that they are an E/One distributor). If no service sticker is on the panel, use our toll-free Service Link (U.S. only) to find a service center near you: 1-866-539-9803. In Canada, use our Distributor Locator.

Some towns take care of the grinder pump service for residents. Check your town's web site for information.

Q: What if the power goes out?
A: Limit your water usage as much as possible. The tank has storage capacity and should be adequate for the short term because you are not using the dishwasher, washing machine, etc. When the power comes on again, the alarm may go off for a short time – this is normal because the water could be above the pump’s alarm level and the pump needs a few minutes to pump down the tank to a normal level. If the alarm does not turn off, call for service.

The best way to handle power outages is using an alarm panel that is equipped with a Remote Sentry Module and a generator receptacle.  The Remote Sentry is a remote alarm with a buzzer & LED that indicates a high water alarm even if the power is out, when it is connected to the Remote Sentry Contacts in the panel.  So, the home owner can use the water until the Remote Sentry indicates that the tank is full, then they plug a 6500W generator into the receptacle on the panel, the pump comes on, pumps down and they can continue to use water.

Q: I'd like to get a generator. What kind of generator do I need?
A: E/One recommends a good quality, 6500-watt generator for starting the pump.
