Suggested Installation Tools & Methods
7/16” socket wrench with shaft extension or 7/16” nut driver
Adjustable Wrench
Flathead screw driver or ¼” Nut Driver
Retrieval ropes longer than the desired installation depth. (Optional)
Marker Buoy (Optional)
Warnings and Suggestions
When installing do not use boats that tip easily, such as a canoe. Follow all boating
safety rules and regulations, including wearing a PFD. (Personal Flotation Device)
Make sure to unroll any rolls of SureSink tubing that have been received before
installing the diffuser. Unrolling the tubing will make it less likely to kink as it is being
taken out with the diffuser to the installation site. Make sure to also unroll and connect
any additional rolls of Suresink before going to the installation site.
Using a retrieval rope coupled with a buoy will allow for easy retrieval of the unit if
maintenance is ever needed or the need to move the diffuser arises.

your box, the tubing
