We just purchased a house with a pool that was built in 2005. We have 2 Pentair spa lights, 1 in the pool, and 1 in the hot tub. Also 1 Pentair Sam pool light. The SAM pool light and the spa light both trip the gfci all of the time. The SAM light is completely rusted, due to a cracked lens, while the spa light is completely dry but will still trip the GFCI. After several days of troubleshooting I have come to the conclusion that they need to be replaced. I have purchased two Pentair Led lights to replace both of the bad lights. My question is that on both of the lights I will need to pull the new power lines through the conduit. It is less than 15 feet in total distance for both lights through separate conduit. Is there anything that would help make this a simpler task? I have never pulled line through conduit before so I am nervous about the line getting stuck or broken in the middle. Anything else I need to know before trying this on my own? I had a pool company come out but they wanted an outrageous amount of money, like a 1000 bucks over the cost of the lights, to install the two new lights. I pulled on the SAM light cord and it seems to move freely but have not touched the spa light yet as it will require me disconnecting the power. Any tips would be greatly appreciated.
