Ungrounded Outlets

 
In older homes the original wiring did not have a ground wire connected to the outlets. These ungrounded outlets are easily distinguished by their two hole / slot configuration verses the newer grounded type of outlet that has three holes / slots. Ungrounded outlets that have two holes / slots used in a home that was originally wired in this manner and has not been rewired are considered acceptable.

The problems for the owners of older homes start when grounded type outlets are substituted for the ungrounded type without the necessary rewiring that adds a ground wire to the new three prong grounded type outlet. Grounded type (three hole / slot) outlets may not be substituted for ungrounded outlets unless a ground wire is connected.

An exception to this rule is allowed by the National Electric Code, when the outlet is protected by a ground fault interrupter (GFI or GFCI).

There is a correction available for those home owners who do not want to rewire the entire house.  Replace the outlets with Ground Fault Interrupters. There are two types of GFI available, one takes the place of the regular circuit breaker in the load center. The second type that is available takes the place of the standard outlet and replaces it with a special GFI protected outlet. These are commonly used in the kitchens and bathrooms of newer homes. Most people know them for their black and red reset buttons.

A surge protector plugged into an ungrounded outlet will not operate as the manufacturer intended. When a large surge or spike hits, the surge protector uses the ground wire to take the "hit" away from the protected equipment and send it safely to ground. If the surge or spike is not sent to ground by the surge protector it will destroy the delicate electronics you were trying to protect. The warranty offered by the surge protectors manufacturer offer, is only valid if the surge protector is used in a properly grounded outlet.

 

 

Garage Door Safety

Automatic garage doors are required to come equipped with safety features to prevent accidental injury. One of the most important features is auto reverse. The door opener should sense an obstruction and stop and reverse. This prevents rhe door from exerting downward pressure and crushing anything trapped under it. As home inspectors we test these functions, and as a home owner you should do the same. For more information on the safety features and methods for testing please click the link.

Plumbing Traps, Knowing Right From Wrong

 Why we want P-traps vs. the old style S-traps.

 An S-trap is obsolete and illegal because as the water leaves it, it can cause a condition called back syphonage, it pulls all the water out of the trap, leaving a dry trap. Dry traps let sewer gases flow back up through the fixture into the house. P-traps are designed to prevent syphonage. The trap retains a small amount of water after the fixture's use. This water in the trap creates a seal that prevents sewer gases from passing from the drain pipes back into the home.

Smoke Detector Locations

Smoke detectors save lives. Do you know where they should be in your house? It is required of new construction to have detectors in every bedroom and at least one on each floor including basement. New homes require the detectors to be hard wired and interconnected, which trigers them to all go off when one detects smoke. I also recommend having one in the garage. If your home is older the detectors are not required to be hard wired, but it is a very good idea to install them in all the requred locations.http://www.nfpa.org/itemDetail.asp?categoryID=1648&itemID=39907&URL=Safety%20Information/For%20consumers/Fire%20&%20safety%20equipment/Smoke%20alarms/Installation%20and%20maintenance%20tips

The Importance of Proper Bathroom Venting

   Lack of proper venting in bathrooms is a very common occurence. Simply not having any venting or improper vent terminantion. Proper venting is critical to removing moisture from your bathrooms. This moisture can cause many issues, the biggest issue being mold. Mold in the bathroom on walls and ceilings, and mold in the attic if not properly terminated to the exterior. Most of us will not travel to our attics too often and the ongoing effects could be creating serious damage and health implications.

Inspecting Your Roof

Inspect Your Roof and Flashings
Checking annually is a good idea but even better is to check in the fall before winter weather and again in the spring after the winter. In New England we can have extreme weather events throughout the year and during these events are when most roofs can suffer damage beyond normal wear and tear. Again the goal being to catch and repair the situation before it causes other major issues.
