How to Find Proper Drain-Cleaning Equipment

To make sure drain-cleaning equipment can handle the most demanding plumbing maintenance tasks in a facility, include answers to these questions in specifications:

• What is the range of pipe inside diameters to be cleaned?
• What power source is required? Electric? Pneumatic? Manual?
• What kinds of fittings are required? Screw-type? Root cutter? Short radius for sharp turns?
• What length cable? 25 feet? 50 feet? Longer?
• Are the proper type backflow preventers specified to protect the potable water supply when using flushing hoses?

When using a pressure washer for drain cleaning, the two most important questions to ask before selecting nozzles are: What is the machine's flow in gallons per minute? What is the machine's pressure in pounds per square inch?

Higher flow rates result in faster cleaning of loosened material.
