How do I check a maple syrup operation’s tap lines and evaporator?

Begin in the bush. Ask how the lines are laid out, how old each section is, how leaks are found and fixed, and who does the work each year. Look at the main lines, fittings and tank connections. Ask how the seller handles storm damage and animal chewing. Lines that are patched year after year may be near the end of their life.

Then look at the sugar house. Ask the age and make of the evaporator, how it is fired, how it is cleaned, and what has been repaired or replaced. Look at the filtering, the storage and the room itself. Ask how fuel is bought, how much is stored and what the seller does when a boil runs long. Ask whether anything is leased or pledged to a lender.

Finally, ask for records. Sap flow, boil days, yield and sales by season help show how the system performs. Ask what the bush can still support, how many trees are tapped and how many could be added. Have a maple equipment specialist or an experienced producer look at the system, and ask the seller what they would replace first.

Key takeaways

• Trace the lines from tree to tank and ask how leaks are found and repaired.
• Inspect the evaporator, filtering and sugar house, and ask about fuel and cleaning.
• Ask for seasonal records and a replacement list from an experienced producer.
