Plumbing has a two-fold purpose. On the waste side,
the plumbing system is designed to rid the house of waste and water. On the supply
side, the plumbing system is designed to provide clean potable water to each point of use,
in a safe and reliable manner.
Look At: The type of materials used for the main supply line to the house,
the internal supply lines, and the waste lines. Are any areas at, or close to, their
design life? Are any areas leaking? How is the water pressure and flow? Has
any "do-it-yourself" work been performed (i.e. improper venting, glue-together
plastic supply lines, etc.)?.
Typical problems we see are:
"Do-it-yourself" plumbing repairs (the worst I've ever seen was where
someone used sections of garden hose and clamps to provide supply water to his newly
remodeled basement bathroom); cross-connection issues where waste water can
contaminate drinking water; problems associated with connecting dissimilar materials (i.e.
galvanized steel & copper lines); old lines at the end of their design life; poor
water flow & pressure; blocked floor drains; out-door faucets not upgraded to
frost-proof type; etc.
