" John. Is the oldest licensed utility contractor in the city Cambridge they've been doing water service and other utility connections for quite along time. And it showed up here this morning disparity -- They were quite relieved to see that are full of conditions here are very favorable we have solved soft lay. And lots of sand so they've made quick work of digging through about fifteen feet from the front yard getting."

" Through the foundation was the tougher part of the job. You've got a stone that's locally referred to with iron stone we think it comes from the -- part of Massachusetts and it's a real tough stone to breakthrough. But we are now at the point where we can talk with with Dick -- about the work that has to be done right here. First question I want to ask is. Why does a homeowner need to do this why bother to replace the existing water service life. The existing service that was in the up ground right now the service's -- galvanized leveling quite. So if you do have a lead lined pipe. That indicates that it is a replacement pipe writes that the original hundred year old pipe that is correct well. And yet it's still poses a certain amount of health hazard I know that the town recommend is that -- changed these pipes. Doesn't require it to but they recommend it to change them. And I know that very often people are warned that it's a good idea. Have the water flow for a minute or 2 in the morning before you drink any beer tap water that is correct. We have gotten now to the point that you've. Broken through the foundation what's happening next the next step Bob is we're going to push a driving. Through -- come through the banking here. We'll take the driving -- back. That we got in trough buffet we got to ask yourself -- go ahead and push the -- drive the pipe -- of their inheritance. So that's -- good this is a solid iron pipe yes it is. And it's basically gotten may be eight feet across the foundation and through the remaining four feet of soil here that we haven't excavated so that we haven't bothered -- bushes and plants or where. And now that. Yeah now you got a temporary cold air that that rod as -- And you can just push the copper through there there hopefully you won't an obstruction on the Koppel come Arturo okay. Now why do we go to copper what's the advantage of copper. The caught for quite. Being the type of metal that is still will avoid corrosion you'll never have restrictions on the morning's -- quite. And they just didn't have that available to them that kind of fight available to them when they replaced the service may be fifty years ago that is correct. Now does the size of the pipe indicate that you'll have stronger volume of water in the house they one inch Koppel provide you with. More volume of water as opposed to -- blood line which has corroded threaded connections OK which in many cases have held up to the light. You may only see a pinhole you're."
