Why You Should Keep Your Water Heater Properly Maintained
Dangerous Water Heater
Dangerous Water Heater

During the course of a home inspection I remind clients that in order for appliances to operate safely and efficiently, they should be maintained on a regular schedule as recommended by the manufacturer.  In the photos above you will see a water heater that I came across at a home inspection.  Clearly there are some combustion issues.  This is evident by the flame blow out at the main burner at the bottom of the unit, as well as the soot blow back at the upper vent stack.   This home was vacant and the gas was shut off so I could not check to see if the flame was proper and if the unit was venting properly.  Flames blowing out of the bottom of the water heater could result in ignition of combustible materials close to the water heater.  The back draft at the vent stack would be releasing Carbon Monoxide into the room.  I recommended service prior to operation to ensure that the unit operates properly.

 


Rochester MN Home Inspector Finds Unsafe Wiring

Unsafe Wiring

During a recent home inspection I came across this electrical wiring that was in contact with both a heating duct and the water heater exhaust vent.  The wiring against the exhaust vent has the potential of melting, allowing the bare wires to come in contact with the metal vent.  This could result in electrocution if  someone were to come in contact with the metal vent.


Rochester MN Home Inspector Discusses Dryer Fire Hazards

Corrugated Dryer Venting Clogged With Lint

If you have had a home inspection by HomePro Home Inspections you know that when I come across flexible, corrugated dryer venting, we discuss the potential for fire hazard.  Dryer manufacturers recommend solid metal smooth bore venting to provide for better air flow.  Considering how important this subject is, the stakes involved and the frequency of dryer fires in the home, the topic deserves more attention. 

Clothes dryer fires account for nearly 16000 fires annually, with 80% of them occurring in residences, resulting in 15 deaths and 300 injuries per year.

New home trends tend to locate laundry room in more hazardous locations away from exterior walls.  Locating laundry rooms near the center of the home results in longer vent lengths.  Failure to keep these long runs clean is the leading cause for clothes dryer fires.  In addition to fires, lint build up will prolong drying times, wasting energy, and contributing to even more lint build up.

Recently I came across a new product called Lint Alert.  Lint Alert is a home safety device that measures and displays the back pressure in the dryer exhaust vent.  The back pressure in a dryer vent will increase as lint builds up and restricts the airflow.  When the backpressure increases to unsafe levels, the lint alert will alarm, letting you know that your dryer vent needs maintenance and cleaning.  You can learn more about the Lint Alert at www.lintalert.com

Home Inspection Uncovers Unsafe “S” Trap
YouTube Preview Image

In plumbing system, a trap is located below plumbing fixtures to prevent sewer gasses from entering the building. You will see in the attached video from a recent home inspection that there is what is referred to as an “S” Trap. In many locations, plumbing codes do not allow “S” Traps as they are prone to siphon out the water seal even if properly vented, thus allowing sewer gassed to escape into the building. The accepted type of trap is called a “P” Trap.  Your home inspectors report should document where “S” traps are in use.


Home Inspection Detects Hazardous Gas

On a recent home inspection near Rochester MN,  I came across what appeared to be a blocked chimney flue.  Both the furnace and water heater were functioning properly with nice blue flames.  I was however getting back draft Carbon Monoxide exhaust from both appliances.  Carbon Monoxide does not smell or taste and can lead to death if occupants are over exposed.  I recommended to the homeowner that they immediately get a qualified Plumbing & Heating contractor to resolve the condition.  In addition, it was recommended that Carbon Monoxide detectors be installed on all levels of the home.

Home Inspection Points Out Improper Vent Termination

Bathroom Vented To Attic

Bathroom and Kitchen improperly vented to Attic Roof Vent

You can see from the pictures above that it is important that the home inspectors do a carefull inspection of the attic areas to insure that all venting exits through the roof.  These pictures are from two separate home inspections that I did over a couple of weeks.  In each case, the home owner had added either bathroom and/or kitchen exhaust vents and terminated then in the attic. They were all aimed at a roof vent in an effort to exhaust to the outside.  You see in the one picture that the handy work failed and the duct never even made it to the roof vent. 

To insure proper ventilation of bathrooms and kitchens it is important that all vents exit the roof through proper roof vents.  Venting to the attic adds moisture to the attic area which can result in icing and excess moisture in that attic area.

Rochester MN Home Inspector Discusses Radon Health Risk

Following a comprehensive assessment of environmental cancer risks, the President’s Cancer Panel released a report on Thursday, May 6, Reducing Environmental Cancer Risks: What We Can Do Now,  calling for new  personal and policy action to reduce the risk due to radon exposures in homes, daycare facilities, schools, and workplaces.
 
Radon is a radioactive gas that accumulates indoors and is the leading cause of lung cancer among never smokers.  The National Academy of Sciences estimates that 22,000 people die each from radon exposure in their homes.  In the United States, radon concentrations are measured in units known as picocuries per liter (pCi/L).  Although no exposure to radon is considered safe, the U.S. Environmental Protection Agency (EPA) has set a level of 4 pCi/L as a level where radon reduction is clearly needed. 
 
“The President’s Panel’s report is an incredibly important reminder that each of us and our elected officials must do much better to reduce the terrible risk of indoor radon exposure,” according to William Angell, President of the American Association of Radon Scientists and Technologists.  Angell adds the report reinforces the World Health Organization’s (WHO) new radon recommendations for lower radon concentrations at which people should take action to reduce exposure.
 
The President’s Cancer Panel calls on EPA to evaluate reducing the Agency’s 4 pCi/L Threshold for Action.  In late 2009, WHO called for countries to set action level at 2.7 pCi/L as well as to improve rates of radon testing and radon reduction.
 
The Panel urges families to periodically tested their homes for radon since concentrations can change over time.  Further, all home buyers are advised to test for radon in any home they may consider purchasing.
 
The report calls on Congress to support improved radon testing methods and provide tax deductions to encourage radon mitigation of existing homes.  Senator Amy Klobuchar (MN) announced on April 30 a bill she is introducing that implements many of the President’s Cancer Panel’s recommendations.
 
State and local governments were called to implement building codes to require radon control in new construction and to regularly test all schools, day care centers, and workplaces.  
 
 The National Cancer Institute report, Reducing Environmental Cancer Risks: What We Can Do Now is available at  http://deainfo.nci.nih.gov/advisory/pcp/pcp08-09rpt/PCP_Report_08-09_508.pdf

Home Inspectors Discover Serious Water Heater Venting Problem

Hot Water Heater Vent Flue Disconnected

At this home inspection I came across a hot water heater in a utility closet in which the vent flue had become disconnected at the ceiling.  In addition to the exhaust and CO venting directly to the closet, you can see that the paper on the adjacent sheetrock is heavily charred from the exhaust heat. 

The home owner stated that the water heater was professionally installed less than 6 months ago.  Lucky for them, the door to the utility closet sealed fairly securely which slowed the flow of CO into the living area of the home.  I recommended to the home owner that they contact the installer immediately for emergency repairs to the vent flue.

You cannot see or smell carbon monoxide (CO), but at high levels it can kill a person in minutes. It is the leading cause of poisoning death, with over 500 victims in the United States each year.  The initial symptoms of CO poisoning are similar to the flu but without the fever. They include headache, fatigue, shortness of breath, nausea, dizziness, vomiting, disorientation, and loss of consciousness.

Blocked Furnace Venting Found During Home Inspection

Furnace Vents

The recent heavy snowfall and drifting brings one more thing that Rochester and Southeastern MN homeowners need to keep an eye on.  Home owners with High Efficiency, direct vent furnaces and water heaters need to check to see that the venting has not been drifted over with snow or blocked.  These systems typically vent through the sill plate of the home, close to ground level through a white PVC piping like in the photo above.  Drifting snow has the potential to block these vents, causing your furnace or water heater to not operate.  These systems have sensors that will detect blockage which will shut down the system.  This home inspectors recommendation is to go out and check to make sure these vents have adequate clearance after a heavy snow fall.  If they are blocked, simply clear the snow out of and away from the vents, and you should be good to go.  If there are still problems, call your local Rochester MN heating contractor to resolve the issue. 

I was discussing this with a client recently at a home inspection.  The client’s Realtor spoke up and said that he learned this lesson last year.  Cost him $75 to have someone come and clear the snow away from the venting.

Rochester MN Home Inspector Finds Bees In The Basement

Basement Bee Hive

Here’s another good reason you should make sure all exterior openings are sealed.  During the home inspection I usually discuss with my clients the importance of making sure that all exterior openings are sealed so that moisture and insects can not infiltrate. 

This home had been sitting empty for quite a while.  The bees found a way in through a disconnected dryer vent and built quite a large nest.  Lucky for me, someone has smoke bombed the place and killed all of the bees…. there were hundreds of dead bees throughout the home, mainly in the basement.

You were very thorough and took the time to explain every question. The home inspectors report was helpful for a single female, first time home buyer. The photo pages were beneficial in showing where repairs were needed.

Krista K, Rochester, MN

Very pleased with the home inspection process from start to finish. Findings were very specific. We learned a lot about the house that we were not aware of. You are friendly and non intimidating, just the kind of person people are hoping to work with.
