Make it short and sweet.
Take your 10 lb sledge, and break off the pipe at the ground.
Then walk away.
That should work well.

I use a Honda EU 2000 as my only generator.
It only gets around 2 tanks a year on it.
However in terms of fuel efficiency, you can't beat the ecothrottle
units ( honda, yamaha, )just amazing, better than diesel, and way
better than propane. But really only good for small usage. If you are
Thanks to those who helped me out. I had a stickler inspector to deal with.
For instance, he interpreted all inverters (-8- SunnyBoy 7000 watt) to
require a grounding electrode connected from each inverter chassis to
building steel. Anybody else required to do this out there? The good thing
is fina
After 15 years i recommend the small ones only for emergency use if there is
nothing else to do the job. In most cases they will go a tolerabe job of
charging but when a large load kicks on it gets real funky fast and the
inverters will probably kick it off if adjusted well.

In my experience of six years, we have had to "do business" with a GC or
other intermediary three times. We haven't had a real problem, other than
slow payment. There have been other times where a 3rd party received some
sort of management fee from the client, but that iwas not part of our
contract
My experience over the years as an electrical contractor is that GC's charge
the owner 15% to manage your sub trade. Over the years we've done mostly
large scale electrical. When entering the Solar industry in 1999 we started
doing residential with a few commercial installs.
The same rule applied
Thank you everyone for your input. The client has confirmed that there is a

Ryan,
You have answered your own questions.
1) "he has been a very high maintenance customer". Been there, done that,
even fired a few HMCs over the years.
2) "i can waive the labor cost and tell him to find someone else at this
point". Do it.
One more suggestion: You have received a consistent

Our engineer has told us that filling a pipe with concrete (for a pole mount
application) is not strengthening it.
As soon as the wind blows & the pipe bends/twists the concrete begins to
break up inside, making it useful only as a water wick.

Greetings! First off, thanks to Allan, Brian and Peter for your input on

Don't know how to do it gracefully but I would refuse to install it untill
the pipe met spec. I don't think putting rerod in it and filling it with
concrete would help. Have him re-do it or don't touch it with a 10' pole.
Have you spoken to DPW, for suggestions? At least they can back your
opinion.
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 Sch

You know how to break cast iron pipe in a clean break flush with the
ground? Hit it with a hammer. It snaps clean off, flush with the
ground. Works with clay pipe too. Concrete may provide additional
strength in a compressive mode, but has nearly zero strength in tensile
(stretching) mode. Roy
A few years ago I saw a similar installation where the clamping bolts on the
mount itself shattered the (very brittle) cast iron pipe that had been used at
the top.

Ryan,
I would be very wary. If DP&W says it is engineered for Sched.40 steel
then that is what it is most likely warrantied for. I don't do anything
that would void a manufacturers warranty. After 21 years in this
business it is one of the most important things I've learned. If DP&W

Filling the pipe with concrete would strengthen it quite a bit but will also
cause condensation on the outside during a lot of the year.
Did I mention that pouring concrete from a half full 5 gallon pail while on a
ladder is a real pain.

Hi Drake --
The biggest problems we see up here with small, inexpensive generators
like Coleman are from altitude. Our community is at 8200 feet elevation,
and on many such generators there is simply no adjustment on these
machines to make them run well at this elevation (as per our local
