Our pool was remodeled in 2007. When they put in the electrical for the spa light, they did not use a junction box, as the old spa had, but ran conduit a long twisting route from spa to controller. We had to replace the Polaris EOS Command Center and thought while we were at it we'd upgrade the lights. We're using a different pool contractor, and they were able to pull the old light and wiring out, but cannot pull the new wire through the long conduit run. Any suggestions... some type of lubricant even though the conduit is full of water? They are looking at having to tunnel under the deck to the spa light, (something I really want to avoid) then install a new junction box, Does code require use of a junction box? Thanks.
