Some Quick Answers

We took some time to compile some of the questions we hear most often, so we can provide some quick responses and guide you in the right direction.

Jet Pumps

Priming Your Jet Pump

  1. Remove priming plug.
  2. Prime system by filling pump and suction pipe with water.
  3. Replace priming plug loosely.
  4. Turn pump on and make sure pump is delivering water. If no water is pumped within 15 seconds, turn pump off and re-prime.
  5. After pump is primed, tighten priming plug.


The pump housing and piping MUST BE MANUALLY PRIMED (filled with water) the first time, before running the motor, or damage will result that WILL VOID YOUR WARRANTY.


On existing deep wells, make sure proper ejector is being used. If ejector does not match pump, the pump may not build pressure and may not prime properly.

Winterizing Your Jet Pump

  1. Turn off power supply to your pump.
  2. Open a faucet to drain water from tank. Our pressurized diaphragm tank will allow most water to escape, eliminating potential freezing hazards.
  3. Drain water from pump by opening drain plug on bottom side of pump housing.
  4. Before using the pump again, replace drain plugs and manually re-prime the pump. Your Star pump is a self priming pump after it has initially been primed with water.

Freezing causes the casing to crack and is not covered under warranty.


  • Do fill pump and plumbing with water before start-up.
  • Do make certain all valves and nozzles on both the inlet and outlet sides of the pump are open while pump is in operation.
  • Do install pressure relief valve.
  • Do ground motor, do not ground to a gas supply line.
  • Do wire motor to correct supply voltage. See motor nameplate and wiring diagrams and check voltage of power supply.


  • Don’t run pump dry (without water).
  • Don’t pump oil, petroleum products, chemicals, cleaning agents or viscous liquids.

Water Well Tanks

Tanks are sized based on the amount of water provided before the water pressure drops enough to turn on the pump. Galvanized tanks are very inefficient and leave most of their stored water in the tank when the pump turns on. Pre-charged tanks are very efficient and will provide you with more water between pump cycles.


Some adjustments will be necessary. A complete set of instructions are included with each pre-charged tank that will help you with the installation.


If you already have a pre-charged tank, simply buy one of the same physical size. If you have a conventional tank, use the tank cross reference chart.

Make sure you have a tank size suited to your present plumbing system. You may need to switch to a higher or lower capacity model to match the system. To select the proper size tank, count the number of fixtures in your home (sinks, showers, bathtubs, toilets, dishwashers, faucets, washing machines, outside faucets, etc.). The proper tank volume is three (3) times the number of fixtures.

For example:

No Fixtures Tank Volume Star Air-E-Tainer Tank
5 14 132661 or larger
6-8 20 132662 or larger
9-11 32 132663 or larger
12-15 44 133517 or larger
16-21 62 136875 or larger
22-30 86 135460 or larger
31+ 119 136876 or larger

If you have a heat pump, hot tub, sprinkler system or irrigation system, choose a tank one model larger.

  1. Tank is pre-pressurized with air at the factory.
  2. When pump starts, water enters the reservoir. At 50 psig system is filled. Pump shuts off.
  3. When water is demanded, pressure in the air chamber forces water into the system. Pump turns on.
  4. When pressure in tank drops to pressure switch cut-in point (30 psig) pump refills the tank.

Sump Pumps

To calculate the amount of water used by a water-powered sump pump, you would typically consider the pump’s efficiency (gallons of sump water pumped out per gallon of city water used), the volume of water in your sump pit, and how often the pump activates. It’s also important to remember that water-powered sump pumps typically operate during heavy rainfalls when the risk of power outages and sump pit overflow is higher, leading to potentially increased water usage during these periods.


Yes, in most cases, it is recommended to drill a weep hole when installing a Zoeller sump pump, or any submersible sump pump. The weep hole, also known as an air relief hole or bleed hole, is usually drilled in the discharge pipe just above the pump’s body and below the check valve.


A sump pump is a device that helps keep your basement or crawl space dry by automatically pumping out accumulated water due to rain or natural groundwater. It’s crucial for preventing water damage and maintaining the structural integrity of your home.


The right model depends on several factors such as the size of your home, the level of water accumulation, and the depth of your sump pit. You can consult our product specifications and reach out to our customer service team for personalized advice.

A battery backup sump pump provides additional protection against flooding during a power outage. It operates on a charged battery and takes over if the primary pump fails or loses power. We recommend having a backup system if your area is prone to power outages or if your basement is finished or used as a living space.


Pedestal sump pumps have their motors mounted above the sump, which keeps them dry and may facilitate easier maintenance. Submersible sump pumps are designed to be placed underwater in the sump pit. They are typically quieter and can handle larger volumes of water.


Common troubleshooting steps include checking the power source, ensuring the pump is plugged in correctly, inspecting the float switch for proper operation, and clearing any clogs or blockages. Refer to our troubleshooting guide or contact our support for assistance.


Higher horsepower pumps can move water more efficiently and are typically used in situations with a high volume of water or where the water needs to be lifted to a greater height. Choose a higher horsepower pump if your home requires extensive water management.


Yes, always ensure you are following all local electrical codes and safety requirements. Do not touch the pump or water with wet hands or feet when the pump is plugged in. Refer to your Zoeller sump pump manual for detailed safety instructions.


Sump pumps are not designed to remove debris. They are for water only. Ensure that your sump pit is free from debris to avoid clogging or damaging the pump.


Unusual noises could indicate a potential issue, such as an obstructed impeller or worn bearings. Turn off the pump and unplug it before performing any checks. If the issue persists after checking for debris and ensuring proper installation, contact Zoeller at Home support.


The Zoeller backup system will automatically activate when the primary pump fails or if the water level rises above a certain level during a flood, ensuring continuous operation. Ensure your backup system is tested regularly and maintained according to the instructions.


Sewage Pumps

A sewage pump is designed to pump sewage waste and effluent from a sewage basin to a septic tank or a sewer system. It manages waste that is not suitable for a traditional gravity-fed system, typically found below the sewer line like in a basement bathroom.


If your home has bathroom facilities below the main sewer line or septic line level, you will need a sewage pump to move waste to the higher elevation. Sump pumps are only for removing groundwater and are not suitable for transporting solid waste.


Yes, Zoeller sewage pumps are specifically designed to handle toilet waste and other sewage materials. Please review the pump specifications to ensure you choose the right model for your needs.


A sewage pump can handle sewage solids up to a certain size but does not have grinding capabilities. A grinder pump pulverizes solids into smaller particles to prevent clogs in the piping system. Choose a grinder pump if your system requires waste to travel a long distance or if it’s prone to clogging with traditional sewage pumps.


Regular maintenance depends on usage, but inspecting and cleaning your pump once a year is usually sufficient. Always follow the specific maintenance instructions for your Zoeller sewage pump model.


Consider factors such as the number of fixtures in the home, the distance to the septic tank or sewer system, and the vertical lift required. Our Zoeller at Home support can help determine the appropriate pump size based on these criteria.


Yes, our sewage pumps can be used in conjunction with septic systems. Ensure that the pump meets the requirements for your particular septic system design.
