EasyPro Underliner Vent System - 4" End Outlet Fitting and 6" x 150' Roll Yellow Pine The horizontal float mounted AquatiClearEasyPro lives up to their name with this great and unique vent system made to vent air, methane or water out from under a pond liner to prevent the liner from bulging upward. Just install the liner vent while building the pond, prior to installing the liner and putting in the decorative rock. Anyone who has ever had a liner lifted will understand how valuable this could be.
