Water Pipes – Drip, Drip, Drip
The best piping material for water pipes is copper. It will last forever and is resistant to hard deposit build ups which can impact the amount of water flowing through the pipes. Copper pipes are also the sign of a quality construction effort as they tend to be more expensive than alternatives.
If you see PVC water pipes anywhere other than on the sprinkler system or from the main street line to the house, red flags should wave before your eyes. The presence of PVC piping is an indication of an owner doing the piping themselves, as most construction companies will not use PVC. In a majority of locations, such use of PVC is outright illegal. Do not buy a home with PVC piping in the walls! Ever!
