10. Once all pipe connections are installed and properly secure, open the STS
Media filter’s top access port. Inspect the PVC underdrain to be sure all parts
(laterals) and connections are secure and nothing is broken. Fill the STS
about one-third to half full with water. Then, SLOWLY add the appropriate
amount of sand (refer to media sand chart above).
It is important that the
sand be added slowly so that no damage occurs to the laterals on the
underdrain assembly.
Spread the sand level within the tank, then close and
secure the access port.
