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.

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.

There is a fish store near me that was (at least a few years ago) wired
entirely in white PVC water pipe. The most disturbing thing was the
sharp 90 degree elbows. I don't know how this passed a comercial
inspection (or how an inspection could have been avoided)...

*I agree with RBM. 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?

Individual conductors Red,Black,White,Green Looks like #8, at least
bigger than 10.

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.

*If the unit is GFI protected and bonded properly and there is a disconnect
within sight it might as well be left alone. 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.

I used sched 40 white PVC for an overflow in my pond, spray painted
the exposed areas green with Rustoleum paint. 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.

'Pends on the Standard to which is certified--same PVC product may be
have multiple ratings & markings i.e. PVC Sch. 40 & EPC 40.

Pressure testing & rating at standard temps for the plumbing products,
low tolerance lead/chemical leaching contamination to potable standards
(D1785 & D2265).

Some mfg's manufacture some PVC products that are dually tested and
labeled/marked & NSF certified ASTM D1785/ASTM D2265/NEMA TC-2/UL 651

Probably biggest difference is most/all(?) of the EPC products are rated
for UV exposure whereas most/all(?) plumbing products aren't. This is
important for outside applications where conduit may be in sun.

But, if markings are obliterated it's impossible to tell apart visually,
dimensions are same for each size/schedule between the two.

Other than the gray color vis a vis white for plumbing, that is...

All the plumbing PVC I've seen is white, all the electrical grey.
Seems you could very easily visually spot something out of place.
What color is that dual use stuff?

From a practical sense, conduit has U/V protection but gray conduit
may also have a slightly higher melting temperature. (90c) The whole
issue is really just the U/L listing for each. Water pipe is pressure
rated and conduit is impact strength rated. They may be exactly the
same but you can't prove it to an inspector.

No difference except for the color and fittings.

Not exactly true. Water pipe is certified not to leach unacceptable
levels of chemicals into the water. 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.
