 | House plumbing pressure? |

Question: Our house has city water for everything but the outside faucets, which are fed by a well. The well has died, so I plan on cutting the copper pipe coming from the well, and connecting it into the copper city water line just after the shutoff valve where it comes into the house. Luckily, the two lines are only about 3 feet apart from each other. I have never worked with copper pipes before, only plastic. I thought about practicing sweating joints first on small scrap pieces of pipe, sealing one end, and pressurizing the pipe with my air compressor to check for leaks before I attempt this for real on my house plumbing. What kind of pressure is in a typical house with city water plumbing? I am nervous about this project, cause once I cut into the house line, I will have to finish it, and do it right or I will not have any water in the house at all till it IS right. Any thoughts/tips/suggestions are appreciated!
Answer: -Typical is 60 PSI so test to 100 PSI or more if you can. -Depending on your water prices, you might want to revive the well. Watering can be very expensive. If the outside faucets are not all standard above ground faucets, for instance, if you have a buried sprinkler system, you will need to install anti-backflow devices to avoid contaminated water from being sucked back into the pipes in event of a water system failure. You will have to get ALL the water out of the pipes where you solder or you will not get them hot enough.
