Plumbing inspection

The plumbing system must deliver potable water sufficiently and continuously at a proper flow and pressure rate and at a desired temperature. The system must allow rapid draining of wastewater in a design that prevents backflow. A drainage system must be ventilated to prevent negative or positive pressures in the pipe system and it must include at least one vent to prevent the return of contaminated air into the building.  The vent must lead to the outside (usually on the roof). The plumbing installation must have an adequate number of cleanouts and the plumbing devices such as sinks directly connected to a drainage system must be protected by a water trap.

The inspector will observe in particular the toilets, the drains and the sinks which are known areas for leaks and which are often responsible for damages. All adverse conditions identified during the inspection must be corrected as soon as possible time. Normally, minor leaks with little or no damage simply require maintenance.
