The cable gland and cable entry follow, especially if the cable was pulled carelessly during installation. The driver suffers from the ambient humidity of the plant room and voltage variations.

Then check the cable gland, then the cable entry, following the conduit back to the plant room. A trace of moisture on the conduit side points to the cable entry rather than the glass.\u003c\/p\u003e\n\n\u003ch3\u003eRepairing or replacing a submerged light\u003c\/h3\u003e\n\u003cp\u003eIf only the seal or the cable gland is at fault, replacing them is often enough to get going again. If the body, the glass or the niche are affected, it is better to replace the whole unit. On a masonry pool, removal is done from the front in the existing niche. The electrical connection remains the responsibility of an electrician.\u003c\/p\u003e\n\n\u003ch2 id=\"installation\"\u003eHow do you install a light sealed into a concrete wall?\u003c\/h2\u003e\n\u003cp\u003eInstallation takes place before the pool is finished: the niche and the cable conduit are sealed into the wall, then the unit is fixed into it and removed from the front. The connection is made out of water, in the plant room. Allow for an electrician's intervention for the connection and safety measures.\u003c\/p\u003e\n\n\u003ch3\u003ePlanning the niche and conduit before the pool work\u003c\/h3\u003e\n\u003cp\u003eMark the position of the niche on the plan, taking into account the water height and the swimming axis. The conduit and the cable must reach the plant room with a slope that prevents stagnation. These provisions, made at the right time, are what will make future replacement simple.\u003c\/p\u003e\n\n\u003ch3\u003eConnection and safety measures\u003c\/h3\u003e\n\u003cp\u003eThe connection is made out of water, on a protected circuit, with a conduit suited to buried routing.
