Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

   A properly installed P-trap will always keeps it’s water seal.
If you have S-trap drain, and notice sewer-type odors in the room, you can run the water slowly down the drain for a few seconds to replenish the trap-seal as a temporary fix. But, of course, the best solution is having a licensed plumber bring the drain piping up to modern standards.

   Another requirement of an efficient plumbing drain system is at least one vent pipe that extends above the roof, to allow sewer gas that rises into the drain piping behind the sink traps to exit into the atmosphere. The vent pipe also provides atmospheric pressure to the drains.

   Occasionally, we see vent pipes that terminate in the attic or on an exterior wall near a window. Both of these installations allow the possibility of sewer gas migrating back into the home.

   Although TV home-improvement shows sometimes make installing your own plumbing look easy, doing it right requires both training and years of experience. Plumbing repairs should always be performed by a licensed plumber. The plumbing inside your home is so critical that every building department in the United States requires plumbers to be licensed.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
