Pond Pipe, Hose and Tubing

Reinforced PVC pipes resist crushing when installed underground, and is flexible enough for convenient handling and installation. We strongly recommend to go with a larger pipe than you believe you need, installing a small pipe limits the flow and potential of any feature and is one of the most frequent regrets we hear about.

Pipe Size Trumps Pump Size
Say you have an 8,000 GPH pump and 2" pipe in your pond or waterfall. Although the pump may be powerful enough to produce 8,000 GPH, the pipe will deliver a maximum of 6,800 GPH. Pipe size, not pump capacity, will be the limiting factor in the flow of water in your project.

Pump Outlet Size Does Not Determine Pipe Size
The diameter of the outlet of a water pump is designed to enable the pump to produce GPH. It does not determine the proper pipe size. For example, many pumps producing 7,500 - 9,000 GPH may have a 2" outlet; use a reducer to step up from 2" to 3" and use 3" pipe for optimum performance.

A Single 3" Pipe Delivers More Flow Than 2 - 2" Pipes
The key here is friction loss. Friction loss is the reduction of water pressure which occurs when water travels over distance and through any kind of restriction. The combination of pipe capacity and friction loss of water flowing through 2 - 2" pipes produces a flow of water that is actually less than the volume of water that will travel through a single 3" pipe!
