Hi, we live in a condo in SoCal and discovered that the old galvanized pipes need replacing (I wish we knew that before we moved in!). We're on a tight budget so could use some advice: One contractor said to run the new copper pipes above the drywall ceiling, but another contractor said that it's better to run them behind the walls. Which is better?
Our condo unit is ground floor and has no basement or attic crawl space. We want the job done right, but also trying to minimize tearing open the walls/ceiling to save money.
Any knowledgable advice from the TOH community is much appreciated!
