Dirt or debris from the water or hard water deposits lodged between the inner cylinder
wall and the seal are the causes of most leaks. A very small particle which may not be
noticeable can still cause a significant leak. Often simply cleaning the seal will solve a
leak problem.
12. Clean the inside of the cylinder by spraying with an all-purpose cleaner (Formula
409
®
or Fantastic®). Wrap a soft bath towel around a broom handle and push it through,
taking care not to scratch the inside cylinder wall.
DETERMINING THE CAUSE OF A LEAK
Most leaks are caused by some sort of dirt or debris from the water getting into the cylinder
and lodging between the seal and the cylinder wall. A very small particle can cause a significant
leak. Often nothing is found since very small particles may not be noticeable at all. Thoroughly
clean the parts, seals, and interior of the cylinder wall and reassemble the lift. Often the leak
disappears after this simple procedure. Some leaks are caused by a seal developing a split,
by hard water deposits on the seal of the inside cylinder wall, or simply by age or wear.
Replacement seals are always available from Aquatic Access.
CLEANING OF THE INSIDE OF THE CYLINDER
To clean the inside of the cylinder, spray the inside with an all-purpose cleaner (Formula 409®
or Fantastic®). Wrap a soft bath towel around a broom handle and push it through the unit,
taking care not to scratch the inside of the cylinder wall.
Never use any oil or petroleum-
based product inside the cylinder, as it will damage the piston and seals.
TO REASSEMBLE THE UNIT
1. Attach piston with four socket cap bolts and 3/16” Allen wrench. Make sure that
bolts go through piston rod by feeling the threads protrude inside piston rod with your
fingers .Tighten snugly but do not over-tighten or the threads in the plastic piston could
strip.
2. Slip top seal (with open side facing down) onto top of piston rod about 5” from top.
3. Slip the top seal into the groove at the bottom of the piston, fitting it into the groove
on the underside of the white piston with the open side down.
4. If you have removed the piston rod and piston through the top of the cylinder, it will
have to go back in through the top of the cylinder. First, put the white spacer tube on the
bottom of the piston rod to help protect the cylinder wall from being scratched by the
