Residential water damage in the United States accounts for billions of dollars annually. Abrupt and slow trickling leaks caused by faulty water and drain pipes were identified by insurance companies as the leading cause. This blog article describes the plumbing portion of CHIs’ home inspection. Which includes; water pipes, drain/waste pipes, gas pipes, venting pipes, and all appliances. 

Prior to arrival our inspector researches the property to determine the type of water supply and waste system present. Our clients are then informed whether the property utilizes municipal utilities(city water and sewage) or possesses a private well and septic tank system. The inspector begins the plumbing portion of the home inspection by locating the main water metering device and supply pipe/shutoff valve. Many older homes were supplied water via Lead piping, which is most hazardous to younger children but easily detectable. The inspector identifies the condition, age, and types of materials used within the system. Most homes are equipped with copper or PEX plastic water piping. Older homes may contain dated, galvanized water pipes which could require replacement before our client takes ownership. Evaluating water pipes for age,corrosion, leaks, and improper installation are important and the findings beneficial.

Upon completion of the water pipe inspection we evaluate the complete drain system. Again, we begin by identifying the condition, age, and type of materials used. PVC drain pipes are most commonly used in newer construction. Occasionally, we discover dated copper or cast iron drain pipes which deteriorate from the inside of the pipe initially.

 The final phase of the plumbing system inspection includes the branch piping and appliance shutoff valves(gas and water) to all the rooms in the house. We operate and inspect each water heater, well pump, water softener, dishwasher, toilet, sink, shower, washer/dryer, and exterior spigot to ensure satisfactory functionality. Dated, damaged, or leaky pipes are photographed and properly documented for the client in our pdf report.

Knowledge of the current condition and approximate life expectancy of the plumbing system is valuable information required to budget for future repair or replacement costs. Pro-active and preventative maintenance can help homeowners avoid unexpected water damage and expenses incurred due to major leaks or sewage backups. According to local insurance companies, the average cost of water damage to a home caused by leaky drains or water pipes is $5,000.
