Common Problems and Solutions

• Tee will not stop leaking. Turn off the system and re-drill a new hole above the old hole.
• Excessive amounts of chemical leaked out. Replace the chemical
• Solution not going into the tree. Make sure pump is working properly. Adjust pump pressure. Do not pound tees in further.
• Tree taking up solution very slowly. The drill bit may have been dull. The tees may be plugged. The chemical may have fallen out of solution. The elm may have Dutch elm disease. Some trees just go slowly. Smaller trees are more prone to this than larger trees. Mornings tend to be faster than afternoons. Very hot days and drought conditions will slow the uptake. Watering the lawn around the tree the night before will increase uptake and is essential during drought periods.
• Tree took up solution fast then suddenly slowed or stopped. Make sure the dosage was accurate for the size and condition of the tree. Small trees usually need less chemical per diameter inch than larger trees. If the chemical is still going into the tree, it is necessary to wait. It is possible to turn off the pump, raise the bucket higher than the tees, and allow the solution to seep in slowly; this usually takes ten to twelve hours.
