The standard rule is that a pond should have 10 gallons of water for every 1 inch of fish. The average length of a mature goldfish can range from 8 inches to 10 inches and some breeds are even longer. The average size of a mature koi is 12 inches. The “gallon to inch” ratio allows fish to thrive, reach their maximum size, and helps keep ammonia levels manageable, which is the leading cause of fish deaths. It becomes extremely difficult to maintain good water quality when the pond is overstocked.

To extend the life of your liner, we strongly recommend using an underlayment. Pond liners are susceptible to punctures and tears caused by sharp rocks, gravel, and tree roots. Underlayment is designed to cushion the pond liner, providing an extra layer of protection against punctures. It also protects the liner from damage caused by insects and rodents. If you have very rocky soil, you may also install a 2 to 3-inch layer of sand first, then the underlayment, followed by the PVC pond liner for additional protection.

No. Salt water will rust the magnet rotor of the pump. Using Beckett pumps in salt water will void the product warranty.

We recommend 2 or 3 times each year to check for any debris that might be clogging the check valve, tank or intake reservoir.

Most safety switches are wired into a low voltage thermostat to shut down the HVAC system that produces the condensate. This safety switch activates when high water is detected. 1502C & 1502UR max voltage rating is 250 volts, 1502S max voltage is 24 volts

No, the safety switch on condensate pumps are meant to shut down the HVAC equipment if it detects a high water level. The safety switch is not connected to the pump motor in any way and will not affect its performance.

All Beckett pumps with a plug are UL/UR certified for use with the plug for your safety. Removing the plug voids all warranties along with any product liability.

1502UR is rated as a limit control safety switch intended to shut down HVAC equipment when high water is detected. It is not rated as a main operating switch connected directly to a pump. An IPC13A pump would be the closest solution to an application requiring a submersible pump controlled by a switch.

Yes, less water will flow through a hose that is smaller.

A general rule of thumb for friction loss in small tubing is 6″ of head loss per 10′ of horizontal run. You should consult a certified plumber for specific recommendations.

Beckett is a wholesale manufacturer and fully supports our distributors who sell to both contractors and in some cases individuals.

  • Safety-Locate
    • Locate buried utilities or plumbing beforehand. Know your local building codes or ordinances that regulate backyard ponds and pools.
  • Elevation-Choose
    • Choose a level site that will not collect rain water that drains off your lawn.
  • Sunlight and Debris
    • Install pond away from falling leaves and other organic matter. At least six hours of direct sunlight a day is best for lilies.
Use this formula:
LENGTH x WIDTH x DEPTH (ft) x 7.5 = gallons
Example: 7ft x 3ft x 15ft x 7.5 = 236.25 gallons
Use this formula:
  • Required liner WIDTH = Max. pond surface width + (2 x depth) + (2 x 6″ border)
  • Required liner LENGTH = Max. pond surface length + (2 x depth) + (2 x 6″ border)
Pre-formed Liners:
Made of rugged, high molecular weight polyethylene, with a 15 year warr
anty. Various shapes and sizes can be used above or below surface. Shape will hold and not change throughout the years. Great for smaller ponds and small spaces in the garden.
Flexible Liners:
Made of either EDPM or PVC materials. Allows for custom pond shapes and sizes. Can create small to very large ponds pending on amount of liner used.
  • EDPM
    • Thick and durable with a 20 year warranty. Highly resistant to temperature extremes.
  • PVC
    • Lighter and more flexible than EDPM. Comes with a 15 year warranty.
