I have a hot tub I need to relocate. Previously it was a flexible liquidtight whip that ran from the breaker panel directly into the hot tub through one of the access ports. With the move I'd like to bury the line to the hot tub. I am planning to use metal conduit from the panel into the ground, then rigid pvc underground. What I'm not sure about is the combination of fittings I should use to make the final run into the hot tub.
I need to pass about 10 ft of flexible liquidtight into the hot tub to make the final connections. Should I transition from rigid PVC in the ground to metal above ground, finally connecting to the flexible liquidtight or is there a better combination. Is it okay to go rigid pvc to the flexible liquidtight at the top (without metal conduit). Finally what fitting would be best to make the 90 degree transition? Thanks and let me know if you need any additional information.
