PVC water pipe for electrical conduit
One of my neighbors noticed the 50 Amp circuit for his spa was in PVC
water pipe. I know PVC pipe can break down in sun light but this stuff is coated with about 4 layers of house paint. Even though it is exposed directly to southern exposure for nearly its entire 20 ft length, given it is about 10 years old and hasnt had a problem I dont think degradation due to UV exposure should be something to worry about. Is there any other reason this should be replaced. It shouldnt be a problem to replace, the biggest objextion is that its going to mess up paint that is about two years old with some fading. Jimmie |

Jimmie I don't know if there is any difference between electrical and plumbing PVC, except for sunlight resistance, but the bigger question would be the competence of the installer. This is a hot tub, a potentially dangerous environment, if the thing was wired incorrectly, so in my opinion, I'd be more concerned about the rest of the wiring, then the pvc. |

The requirements for hot tub wiring are very specific and in addition to being code compliant must be done according to the manufacturers recommendations. What kind of wire is in the PVC? Cable or individual conductors? |

Jimmie PVC conduit is Sch 40 gray sunlight resistant material. My landscaper installed white Sch 40 PVC (unpainted) manifolds ~30 years ago.......the material has been exposed to 1/2 day SoCal sunshine. I'm sure it has become brittle as the backyard manifold broke when someone bumped it with a wheel barrow. I have been told by plastics people that a couple coats of latex paint will give the material all the UV protection it needs but I still use the gray sunlight resistant stuff. If the stuff has been painted for most of its life......I wouldn;t worry about. cheers Bob |

Usually things like this become an issue when the house is sold and the home inspector finds the problem. Then a permit for the work may be requested. |

It has been in full sun for 14 years, water is still flowing into the creek. As long as the paint is intact it's fine. Plastics become weak and brittle over time, though. |

Dear sir hope you enjoy your time.
We want to know what is defence between water pipe and electrical conduit pipe. Best wishes Hamid |

I still see a lot of Rigid Nonmetallic Conduit used as water pipe where UV protection is important but that is generally for irrigation or a fish cleaning station on a dock where the chemicals are less of an issue. |
