Buying a new house is an exhilarating step to take. However, it is fraught with many potential pitfalls and some serious obligations you must undertake. Among these many potential problems, one big risk is often overlooked: the plumbing system. The system can be pressure-tested, but that doesn’t mean it will perform well over the long haul. What a plumbing inspection will seek out are defects—things like poor installation, the use of substandard materials, inferior workmanship, and designs that will cause big problems down the road. Even if the system is up to code (with the inspections that should accompany any new-build), good inspectors will find things that not only harm the efficiency of the system but could also cause significant damage to the house.
A licensed plumbing inspector examines pipes, fixtures, and drainage systems, looking for existing problems or anomalies. This helps determine the condition of the home's plumbing and its future performance. For new homebuyers, understanding the state of the plumbing is vital in assessing the property's overall value. The Cost vs. Value Report (2013) lists "an inspection of the plumbing system by a licensed professional" as one of the top 5 critical factors in determining a home's worth. On a more immediate level, if the plumbing inspector uncovers any serious problems, the prospective buyers can either ask the current owners to fix the issues before they buy or negotiate a price reduction to cover the repairs.
Plumbing systems that are up to date and properly configured offer several benefits to a home. They can save water, which is good for your wallet and the planet. They can also save energy, because if you're heating or cooling water, hot water that's not getting to you quickly is wasting energy. And a room where you can't use the plumbing, because it's not working or because you're remodeling—think bathroom or kitchen—doesn't really feel like a room in your house. For all these reasons and more, it's important to make sure the plumbing in a home you're buying now works, works well, and will continue to work for a long time. And if it doesn't, that its future is guaranteed in some reasonable way.
