Copper pipes are an ok ground, but as an installer, it's my understanding that if you are going to use the copper water pipe as a ground, it has to be within 5 feet of where the pipes enter the house. If I'm wrong, somebody let me know.
As far as doing a job if there is no viable ground, I agree with the other post on here. I won't do a job if I can't ground the system, and though your completion rate may go down a bit, I find that it's only about 1 or 2 a month where you run into that situation, but I'm not going to risk the chargeback. Not to mention the fact that I do take pride in what I do. If I can't do it right, why do it at all?
The biggest frustration I have is with service calls. When I go out to a service call I am expected to bring everything up to code. There are too many times I've gone out to do a $35 service call and ended up running a lot of my cable, trenching new wire, changing fittings, (my fittings) grounding a system (with my #10 ground wire) and on and on.
I'm getting paid a lot less for that then the lazy guy that installed the job originally got.
I guess it all averages out so I can't complain too much, but it still burns me to see some of the really really bad jobs some installers have done.
I can always tell which installers pay for their own coax and which ones have it provided. How many times have we all seen 8 miles of cable strewn all across somebody's roof? How anybody could look at that and call that acceptable is beyond me. Those people are the reason that dish has become so strict.
Although I've never had a chargeback yet, I would like to see dish at least give 30 days to correct a problem, (at the techs expense, not theirs) if there is a qc problem before they chargeback. Not making excuses for bad work, but anyone who works as an installer knows how crazy your workload for the day can get. After working days upon days 14 hours a day sometimes you can get to where you miss something that you may have not even realized by getting in a hurry or just overlooking.
just my thoughts....
