can he do this????... new home being built by a homeowner in an old subdivision

weatherhead is 3 feet above the back of the house, using 2-1/2" sch 40 PVC from weatherhead down through overhang, down 2 stories on the siding, then about 60 feet to the front along the side of the house maybe knee high off the ground... isnt there an ugly clause in 110 somewhere?

mast risers are usually RMC, subject to the poco's specs , otherwise it's common to have an OH service in pvc...

Is the PVC actually supporting the utility service drop?
If so 230.28 requires it be of "adequate strength". I doubt an inspector would approve of PVC. Also, the PoCo probably requires a minimum of 2" RMC.
Regarding the "ugly clause"... see 110.12

Must be Southern California, PVC mast will flex during seismic activity, there by preventing damage to the poco's service drop!!

About the ugly clause, if he doesn't guy off the 3' of PVC mast, it should develop a very nice bend at the roof line.

Hold on, maybe the PVC service pipe is not a mast. Then it might not be a violation. Right? Plus the point of attachment could be connected below the head (and on the house) and this would be a legal service. As for the height of the PoCo meter, that might be a PoCo requirement. Around here the PoCo want's 4-5 feet to the center of the meter. Unless it is on a driveway, then they want it as high as possible with 6'6" MAX to the top of the meter pan.

here's the pictures...... click on the picture to link to it's larger image, each linked photo should take about 20 seconds with a 56/modem, only ~2 seconds on mine

he cut the pvc in half top to bottom, longitudinally, maybe didnt fit???

here's the other side of the vertically cut pvc, and i wonder if the utility will go for the short sweep elbows

he used a flush mount so had to cut into the siding, and then bent the base outward, and i think the trim is the only thing over the flanges, there's not enough space for the edge flanges to be under the siding

it's all schedule 40 with straps anywhere from 3 feet to 10 feet apart

here's the rest....

this is one of the nicest pvc-imc connections i've ever seen...... i didn't make any of this up..... thought you'd have to see it to believe it

last week it had a weatherhead and pvc, this week it was a length of imc and no weatherhead

this pic shows some overspans on his pvc supports

i guess i dont have a problem with the schedule 40 here, because there isnt room for large vehicles to damage it??

That's one ugly installation! I love the PVC to IMC conversion! Did the building department and utility approve this installation?
