that most often allow water to enter
the housing are as follows (refer to

† Mounts that allow water to enter the air path. If
an older horizontal mount is used, replace it
with a new model or ensure there is ample
slope away from the camera dome and a foam
plug is present
† Missing foam plug from entry into the pipe of
the mounting structure
† Missing O-ring on cover, or missing sleeve or
seal on end cap assembly
† Missing Teflon tape around any housing pipe
threads
† RTV or similar sealant covering an air path
† Loose nuts (4) at the top of the housing
† Heater fans not turning
† Bent flange on metal housing that
compromises the gasket seal between the
bubble and the housing
† Plugged drain holes in the bubble trim ring
† Cracked bubble
† Tamperproof screws that are missing or
improperly tightened compromise the gasket
seal between the bubble and the housing
† Ensure lanyard is not caught between: a)
flange and trim ring gasket, and b) trim ring
and sunshield.
