Tubing Cleaning – Methods Used in the U.S.
A wide variety of cleaning techniques are currently used in the maple industry, including rinsing the system with pressurized air and water, or attempts to sanitize with chemical solutions such as peroxide, bleach, or alcohol. However, the effectiveness of these cleaning techniques in reducing microbial populations and increasing annual sap yield is often questionable.
Tubing Theory and Layout
The basics behind determining the best place to install a mainline and laterals in your sugarbush.
Two Pipe Sap Ladder – A Promising Alternative
A two pipe sap ladder consists of a structure of two vertical pipes connecting the lower and upper sections of mainline. It was initially thought that the sap would lift in the pipe on the vacuum side and that air would travel through the pipe on the bush side. Results were not as expected.
Update on the Maple Tubing Sanitation Research in Ontario
In the spring of 1998, a research project was initiated to develop alternative methods for maple produces using plastic tubing systems. Although the results are only preliminary, the development of alternative sanitation methods that may reduce reliance on chlorine is looking very promising.

Vacuum Sap Collection: How High or Low Should You Go?
Questions of how vacuum affects maple sap, syrup and trees have existed for many years, and these issues are perhaps more important today than ever before due to the increasing use of collection systems that can achieve very high levels of vacuum. This article will describe recent research performed at the University of Vermont Proctor Maple Research Center that was designed to answer questions about high vacuum.
