[RE-wrenches] dpw top of pole mount pipe problems

Ryan,

 

I agree with Roy, if you install the PV system on that cast iron pipe,
without any engineering to back it up, you might as well pull out a pistol
and shoot yourself today and get it over with. Unless the wind never blows
where you live, another hole needs to be bored and a the correct Schedule 80
pipe installed. This is not an issue to compromise on in any way.

 

Bill.

Ryan,

Run away now.....that cast iron has no ductile strength. Wind loading from
that really big "sail" will
snap that pole. He would have to guy wire it to make it even somewhat
feasible but I would not
mention that to him!

Good luck with that.....

Wrenches i have a customer that wanted to install a dpw top of pole mount
for 18 sharp 180 watt panels. he installed his own pipe and even after
several reminders by me and a signed contract stating shcedule 80 8 inch
steel pipe he installed a 8 inch cast iron water main.

 

My dilemma is this he claims to wave my liability in this install but he has
been a very high maintnence customer and seems to forget everything we talk
about or he signs. so would you go ahead with the install or is the cast
iron going to shear off and the rack fall over?

 

financially i have met my obligations with the customer i can wave the labor
cost and tell him to find someone else at this point if need be i dont want
to be liable for spilling 18 panels on the ground and my insurance wouldnt
cover it as we went against dpw's recomendations
