I have a water box which stores all the shutoff valves. My toilet hose appears to look like its one unit that goes from the back of the toilet to the wall. There's a small hole on the wall where the hose is coming from. How do I replace that hose?

Is the shut off valve for toilet in water box?

Is there a problem with hose to toilet?

Is there an angle stop (see image) that the hose connects to at the wall? Let me know. Tom

Im guessing you have a pex system with individual lines run to each fixture and a main header with shut offs for each hot and cold to fixtures? If this is correct, they still should have put stops at every fixture, but it sounds like they did not. In this case, I will need to see a pic of what they did, or did not do. A pic of the toilet supply at the toilet will help me to give further advice, okay?
