Buying a new house is an exciting undertaking, but it also brings its own challenges and necessary due diligence. Of the many inspections that a prudent buyer will order, plumbing checks rank among the most important. It's easy to overlook the plumbing—most people don't even think about it until something goes wrong. Yet, a plumbing system is like the circulatory system of a house; without it working properly, the whole house is a bit sick. Cracked or broken pipes, a clogged drainage system, or a faulty water heater can all lead to serious problems and very noticeable symptoms—as in, you'll see and smell things that are definitely not good. So, on with the inspections! A plumbing inspection can't tell you if the system will last another 20 years (and neither can the home inspector), but it can help you avoid a major-league inconvenience soon after moving in.
Besides stopping future surprises in their tracks, plumbing inspections furnish potential leverage in negotiations during the buying process. If a pro finds plumbing problems, buyers can face sellers with the knowledge that the home's plumbing is, at best, in poor condition. Sellers might respond to this knowledge by either doing the necessary repairs that will allow the house to pass a plumbing inspection or by reducing the asking price of the home, which might still be above the fair market value. Either way, the prospective buyers have gained significant leverage over the sellers by merely knowing the plumbing's true condition. And buyers can complete the process with the nice little bow of having gained peace of mind over the home's hidden, plumbed parts.
In addition, plumbing inspections uncover whether a property's plumbing adheres to local codes and regulations. Properties that have undergone renovations (or that are older) might have plumbing systems that are outdated, potentially dangerous, or just plain illegal. Homebuyers need to know whether the systems in the residence they're considering are up to code or not for compelling reasons that go beyond mere financial considerations. Lead pipes, water pressure that is insufficient, or sewage that is somehow backtracking into the home are liabilities that no new homeowner wants to take on. By insisting on a plumbing inspection, homebuyers can at least make sure that these are not concerns in the property they're considering.
