[QUOTE="dennishoddy, post: 3882249, member: 5412"] I get where you're coming from and know your location well as we travel through there annually a couple of times. This section of hillside which about 200 yards long and very steep has 4 layers of bedrock on the way up. As the installer trenched up the hill, and ran into one of those layers of bedrock shelves, they didn't jackhammer them out to keep the cheap schedule 20 pipe at the required 18" or more trench. He put a couple of 45's on the pipe, went over the bedrock and then went back into the proper depth. Whenever a pump kicks on, it generates a water hammer even though it's already under pressure. The receiver tank in the well mitigates some of that hammer but not all. Over time that 45 degree fitting starts breaking the glue fitting as there is no support behind it. Eventually it breaks. We will be following the original trenching to demo the old thin pipe and replacing with the PEX. I have to remove the trees in the path because if I don't, he will have to use the track hoe to do that which will cost time. Time is money and in this case at $150 per hour, I don't want him to waste time pulling trees up and moving them out of the way if I can get in there with a chain saw and clear the trees, so the only thing he has to remove is the root balls. It's been 25 years since I've cleared that hillside so a lot of the trees are 8-10" in diameter. Lots of work on my side, but I'm not afraid of work. [/QUOTE]
