I am purchasing a new construction home, and I opted to just have it pre-plumbed for a utility sink since I didn’t like the sink options they offered. Now that the walls are finished, I expected there to be some sort of pipes or connections sticking out, but there is nothing visible. When I asked where the pre-plumbing is, they said it just means that they made it so a plumber can easily connect to the existing plumbing (I guess for the washer). The construction supervisor was not able to give any details or even point out the location where a plumber would cut into the wall to access it. He said he would have to go back and look at the plans to find out, so I’m waiting to hear back. The up-charge for the pre-plumbing was only $75, but I’m wondering what extra work was done for that fee and how it makes it easier to install a sink later. As I’m researching, I’m not seeing a standard definition for pre-plumbing. I’d appreciate any feedback on what might mean.
