Having Enough Combustible Air is No Joke
Tom Lochtefeld • 21 June 2023
Combustible Air is necessary to run your fuel powered appliances such as boilers, hot water heaters and gas dryers. Fuel needs two things to burn--an ignition source and oxygen (combustible air). In a small utility room with gas appliances, all of the combustible air is quickly used up. If the appliance doesn't get enough combustible air, the fuel doesn't burn all the way and carbon monoxide is drafted back into the home. Bad news for people napping on the couch or watching TV in the finished basement next to the utility room.
See this air vent stuffed with a towel? The owner stuffed the vent with a towel because "cold air was coming in during the winter". Winter is when the boiler is used the most and needs the most combustible air. He was blocking the air with the towel. He's lucky his family didn't die of CO poisoning. This is why we always recommend CO alarms on every floor if you have fuel burning equipment in the home.
High water pressure in a home might seem like a luxury, but it can actually cause serious damage over time. One of the primary dangers is the stress it puts on plumbing systems. Pipes, joints, and fixtures are only rated for certain pressure levels—typically around 60 psi. When the pressure exceeds this, it can lead to leaks, burst pipes, or premature wear on appliances like washing machines, dishwashers, and water heaters. These issues can result in costly water damage and increased utility bills. Another concern with high water pressure is the impact it has on water conservation and energy efficiency. Excess pressure causes more water to be used than necessary, increasing both water and energy costs, particularly when heating water. It can also contribute to erosion inside copper or PEX pipes, which in turn leads to sediment buildup and reduced water quality. Over time, this can degrade the effectiveness of your plumbing and create health and safety risks, especially if the pressure is not consistently monitored. To manage and prevent problems from high water pressure, homeowners should consider installing a pressure-reducing valve (PRV) on the main water line. A PRV regulates the pressure entering the home and keeps it within a safe range—usually between 40 and 60 psi. It's also wise to use a water pressure gauge to monitor pressure periodically. If signs of high pressure appear, such as banging pipes (water hammer), leaking faucets, or running toilets, it’s important to address them quickly by consulting a plumber. Regular inspections and proper pressure regulation can help ensure your plumbing system remains safe, efficient, and long-lasting.
Neglecting upkeep at exterior windows - especially at the north side of your house can lead to many problems. Northern exposure for a home has its drawbacks, primarily due to the limited natural light it receives. Wooden windows don't get a chance to dry out. First comes mold and lichens, then the wood starts to rot. Rotten windows are a significant concern for homeowners. When window frames or sills become rotten, they lose their structural integrity and can no longer provide adequate insulation. This can lead to drafts, making it difficult to maintain a consistent indoor temperature and increasing heating and cooling costs. Rotten windows can also allow moisture to enter the home, leading to further damage such as mold growth, which poses health risks and can be costly to remediate. Furthermore, both northern exposure and rotten windows can negatively impact the overall value and aesthetic appeal of a home. A dark, cool interior may be less attractive to potential buyers, and visibly damaged windows can give the impression of poor maintenance and neglect. Addressing these issues by installing energy-efficient windows and ensuring proper insulation and lighting can help mitigate the downsides and improve the comfort and value of the home.
A rusty support column is often a sign of potential structural issues and should not be ignored. Rust forms when iron or steel is exposed to moisture and oxygen over time, leading to corrosion. When a support column shows signs of rust, it means the protective coating or paint has likely worn away, allowing moisture to come into contact with the metal. This corrosion can weaken the integrity of the column, reducing its load-bearing capacity and potentially compromising the safety and stability of the structure it supports. The presence of rust can also indicate that the area around the column is prone to dampness or has poor ventilation. Continuous exposure to moisture can accelerate the rusting process, causing further deterioration. In a basement or crawlspace, for example, high humidity levels, water leaks, or inadequate drainage can contribute to the rusting of support columns. Addressing the source of moisture is crucial to preventing further corrosion and protecting the structural components of your home. In some cases, a rusty support column may need to be repaired or replaced entirely. The extent of the damage will determine the best course of action. Minor rust can sometimes be treated by removing the rust, applying a rust-inhibiting primer, and repainting the column to restore its protective layer. However, if the rust is extensive and the column is significantly weakened, professional assessment and replacement may be necessary to ensure the safety and stability of the structure. Regular inspections and maintenance are key to identifying and addressing issues like rust before they become major problems.
Mulch around the base of an air conditioning compressor can cause a variety of problems, primarily related to the unit's performance and longevity. One of the most significant issues is that mulch can obstruct airflow. An air conditioner relies on proper airflow to dissipate heat effectively. When mulch is piled around the base, it can block the vents and restrict the air intake, causing the compressor to overheat and work harder than necessary. This can reduce the efficiency of the unit and lead to higher energy consumption and increased wear and tear. Another concern is the potential for moisture retention. Mulch is designed to retain moisture for the benefit of plants, but this characteristic can be detrimental to an air conditioning compressor. Excess moisture around the base of the compressor can lead to rust and corrosion of the metal components. Over time, this can compromise the structural integrity of the unit and lead to costly repairs or even premature failure. Additionally, standing water or excessive moisture can create an environment conducive to mold and mildew growth, which can further damage the unit and affect indoor air quality. Finally, mulch can attract pests and insects, which can find their way into the air conditioning unit. Mulch provides a warm, moist environment that is ideal for various pests, including ants, termites, and rodents. These pests can cause significant damage to the compressor by chewing through wires, nesting inside the unit, or obstructing moving parts. In addition to the physical damage they can cause, pests can also lead to health concerns for occupants if they make their way into the home's HVAC system. For these reasons, it's best to keep mulch away from the base of the air conditioning compressor and maintain a clear, dry area around the unit to ensure optimal performance and longevity.
Burned or melted neutral wires in an electric distribution panel can be caused by several factors, with loose connections being one of the most common. When neutral wires are not securely connected, they can create resistance, which generates heat. Over time, this heat can cause the insulation to melt and the wires to become damaged. Loose connections can occur due to improper installation, vibration, or thermal expansion and contraction of the wires. Another potential cause is overloading the circuit. When too much current flows through the wires, they can overheat and melt. This can happen if too many devices are connected to a single circuit or if the circuit is not designed to handle the electrical load. Overloading can also occur if there is a fault in the electrical system, such as a short circuit or a malfunctioning appliance. Environmental factors can also contribute to burned or melted neutral wires. Exposure to moisture, high temperatures, or corrosive substances can damage the insulation and conductors, leading to overheating and melting. Additionally, rodents or other pests can chew on wires, causing damage that can result in overheating. Regular inspections and maintenance can help identify and address these issues before they lead to serious problems.
This water heater exhaust vent shown below has no slope at all and might even be negatively sloped. A proper vent slope for a gas water heater is crucial for ensuring safe and efficient operation. The vent pipe should have a minimum upward slope of 1/4 inch per foot of horizontal run. This slope helps to ensure that combustion gases are properly vented out of the house, preventing dangerous build-ups of carbon monoxide. Additionally, the vent should terminate at a safe height above the roof to avoid potential blockages and to ensure proper draft. Improper venting can lead to several issues, including poor appliance performance and safety hazards. If the vent slope is too shallow or if there are dips in the pipe, it can cause condensation to form, leading to corrosion and blockages. This can reduce the efficiency of the water heater and increase the risk of carbon monoxide leakage into the home. Ensuring the correct slope and proper installation is essential for maintaining the safety and functionality of your gas water heater. Regular inspections and maintenance of the vent system are also important to ensure it remains in good condition. Over time, the vent pipe can become damaged or obstructed, which can compromise its effectiveness. By keeping the vent system well-maintained and ensuring it meets the proper specifications, you can help extend the lifespan of your water heater and keep your home safe from potential hazards.
An electronic HVAC filter, often referred to as an electrostatic air filter, uses static electricity to trap and remove particles from the air as it passes through the HVAC system. These filters are typically made of metal and can be washed and reused, making them a cost-effective and environmentally friendly option. Pros: - High Efficiency: Electrostatic filters are highly efficient at capturing larger particles like dust, pollen, and pet dander, which can improve indoor air quality. - Reusable: Unlike disposable filters, electrostatic filters can be cleaned and reused, reducing waste and long-term costs. - Cost-Effective: Although they may have a higher upfront cost, their reusability makes them more economical over time. Cons: - Maintenance: These filters require regular cleaning to maintain their effectiveness. If not cleaned properly, they can become clogged and reduce airflow, potentially causing strain on the HVAC system. - Limited Pathogen Capture: Electrostatic filters are not as effective at capturing very small particles, such as viruses and bacteria, compared to HEPA filters. - Potential Ozone Production: Some electrostatic filters can produce small amounts of ozone, which can be harmful to health if levels are too high.
Short or climbable deck railings pose significant safety risks, especially for homes with children and pets. Deck railings are designed to prevent falls and provide support, but if they are too short or easily climbable, they fail in this primary function. Small children, curious by nature, can quickly scale low railings, leading to dangerous situations where they could fall from a considerable height. Pets, too, may easily jump over or become stuck on climbable railings, resulting in potential injury or worse. Additionally, short or climbable railings can cause issues with building code compliance. Most local building codes have specific height requirements for deck railings to ensure safety standards are met. If your railings do not meet these standards, you may face fines, be required to make modifications, and encounter challenges if you decide to sell your home. A non-compliant deck can be a significant deterrent to potential buyers and reduce the overall market value of your property. From an aesthetic perspective, short or climbable railings can detract from the visual appeal of your deck and home. Properly designed railings not only enhance safety but also contribute to the overall architectural style and visual harmony of your outdoor space. In contrast, inadequate railings can make the deck appear unfinished or poorly maintained. Investing in well-designed, safe, and compliant railings not only improves safety but also enhances the overall beauty and value of your home.
Having ivy grow on a chimney or house might seem charming and picturesque, but it poses several risks to the structure and integrity of your home. First and foremost, ivy's roots can work their way into the mortar and brick of your chimney or the siding of your house. This can lead to the weakening of these materials over time, making them more susceptible to damage from weather conditions. In extreme cases, the structural integrity of your chimney or house could be compromised, leading to costly repairs. The roots can also trap moisture against the walls, creating an environment conducive to mold and rot. Additionally, ivy can cause problems with your home's pest control. The dense foliage provides a perfect hiding place for various pests, including insects, rodents, and even birds. These pests can then find their way into your home, causing further damage and posing potential health risks. Ivy also creates a perfect bridge for pests to access higher points of the house, including the roof and attic. Once these pests have made their home in these areas, they can be difficult to remove, leading to additional expenses and headaches. Lastly, ivy can impact the overall maintenance and appearance of your home. The aggressive growth of ivy can quickly get out of hand, covering windows, gutters, and other important features of your house. This can make routine maintenance tasks, like cleaning gutters or painting, much more difficult and time-consuming. Additionally, the ivy can obscure the architectural features and aesthetic appeal of your home, potentially reducing its curb appeal and overall value. In summary, while ivy may look beautiful, it's essential to consider the potential downsides before letting it grow on your home.
Many years ago my wife and I had a date night at the movies and we got a call from the babysitter telling us that the rubber supply hose on the washing machine had burst and there was water everywhere! Luckily her father was home and ran over quickly to turn the valves off. Rubber or plastic washing machine hoses are common due to their low cost and availability, but they come with several disadvantages that can lead to costly damage and maintenance issues. One of the primary concerns is their lack of durability compared to stainless steel braided hoses. Over time, rubber and plastic materials can degrade, crack, or burst under high water pressure, especially in older hoses or in households with frequent washing machine use. This makes them more prone to sudden failures, which can cause extensive water damage. Another disadvantage is their susceptibility to temperature extremes. Rubber and plastic hoses can weaken when exposed to high water temperatures from hot water cycles or fluctuating temperatures in uninsulated areas like basements or garages. These conditions can accelerate wear and tear, increasing the risk of leaks or ruptures. Additionally, rubber hoses may become brittle with age, making them even less reliable over time. Maintenance and longevity are also significant drawbacks. Rubber and plastic hoses typically need to be replaced more frequently than more robust alternatives, such as stainless steel braided hoses. Homeowners must routinely inspect these hoses for signs of wear, including cracks, bulges, or discoloration, to prevent potential failures. While they are an economical option initially, their shorter lifespan and higher likelihood of causing water damage can make them more expensive in the long run. Upgrading to reinforced or braided hoses is recommended for a safer and more durable solution.
