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
    • How to Prime a Jet Pump

      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.

    • How to Winterize a Jet Pump

      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.

    • Jet Pump Do's and Don'ts


      • 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
    • How is it possible for the pre-charged tanks to hold the same amount of water as conventional tanks even though they are smaller?

      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.

    • Do I need to change my plumbing to replace my galvanized tank with a pre-charged tank?

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

    • How do I know what size to buy?

      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.

    • How does the Star Air E-Tainer Work?

      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
    • How Much Water Does a Water Powered Sump Pump Use?

      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.

    • Do You Need to Drill a Weep Hole on a Zoeller Sump Pump?

      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.
