Arrived to the home, client stated that they had flushed their toilet and it did not refill. When I arrived the client stated that the toilet all of a sudden refilled. I flushed their toilet numerous times and it is work properly. The piping for the toilet is wall roughed and it is on an outside wall. That pipe is the only pipe in the bathroom group that is on an outside wall. Everything is working as it should at this time. I advised to the client that there is a way where I could floor roughed the shut off valve so it won’t be on an outside wall anymore. I will leave an estimate for that service.
