    light issues before first fill...Help

    Dear forum members,

    After many months of slow progress after the main structure was completed, mainly advancing during the weekends, I have finally set-up all the electrical wiring. Tomorrow I will finalize the plumbing section to hook-up the pump, skimmer, filter and returns.

    The pool is made of reinforced concrete, and the light niche (pentair) was not fitted properly at the time of pouring. Mainly, the front portion protrudes about one inch from the inside of the wall. But that basically did not bother me... until today. The light is a Pentair Intellibrite 5G white LED.

    After running the cables through the conduit, including the 8 AWG ground wire, I noticed that after tightening the top screw of the light fixture the rim does not create a "perfect" seal on the niche. On the upper half, it looks all right... but the lower portion (the one with the little hook) has a 0.5 to 1.0 millimeter gap... this will flood the inside of the niche. By the way, the niche did not come with any type of gasket, nor did the light.

    I have a few questions:

    1. Assuming that the niche was fitted to perfection... is this gap normal ???
    2. Is the niche supposed to be flooded...? and can the back portion of the light be wet / flooded ???
    3. Pentair does not include the conduit "cord seal grommet assembly" (blows my mind that a cheap seal is not included in this expensive light)... anyway... if I canīt get the grommet on time (I live in the Republic of Panama), can I seal the conduit with expansive foam to prevent water from entering ???

    Many thanks in advance for your advise and help.

    Kind regards,

    Luis

    Hi Luis,
    the niche is designed to be flooded, as is the back of the light. The cable on the light is also designed to be permenantly underwater, so there isnt a need for the conduit plug.


    Hope this helps,

    regards,

    luis
