Flexible PVC Pipe

Know the Difference: Pipe, Hose & Tubing

Pipes, hoses and tubing are the heart of any koi pond, water garden or waterfall system. Whether your project is commercial, municipal or residential, selecting the right pipe, hose or tubing is the key decision to create and maintain a healthy water environment.

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 just 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 less 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!
