The pipeline looks normal, but there are really big problems. This is a hot and cold water circuit in the toilets. There are a lot of joints in the waterway, which will inevitably leave hidden troubles in the future.
According to the regulations, water pipeline piping should pay attention to: 1. The pipeline buried in the wall can not have joints; 2. The open trench must be made after the arc flat for waterproof treatment; 3, the fixed point should use a special pipe card.
