PARANORMAL ACTIVITIES ……IN THE PIPES

We have all heard the tall tales of fisherman, the scary stories around a campfire, and have seen movies about the things that cannot be explained.  There are things that remain a mystery, things that are only found in the deepest and darkest places in the ocean, only move in the night, or things that you just catch a glimpse of out of the corner of your eye. Similarly, Plumbers can share tales of the discoveries they have found in the deep and dark places that only they are brave enough to embark into.

 

Below are the “Top Ten” strangest things on record that have been found in pipes:

  1. Bullets and Explosives Explosives from WWII have been found in the sewers of London, England.
  2. Livestock? – Yes, a cow was found eight years ago when a Chinese farmer lost a cow.
  3. Jackpot!! – A plumber was called out because a gravity line was blocked. The quarters filled two five-gallon buckets resulting in a $12,000 find!
  4. Sorry, I missed your call! – Smartphones
  5. “It’s not mine” – Contraband
  6. Something to chew on – Dentures

5 CAUSES OF FROZEN HVAC COILS

News flash, it is Summer, it is HOT! The last thing you would expect to see is ice on the coils of your HVAC system.

Below are a few potential causes for frozen coils on your HVAC system:

  1. Dirty air filters may cause frozen coils

Your HVAC needs clean airflow throughout the system to function properly. Dirty filters can obstruct air from getting in and out of your system. If the air does not circulate around the coils, the coils get too cold, and lead to ice accumulation on the coil.

  1. Broken fans can decrease airflow and cause coils to freeze

Even if your filters are clean, it will not help unless the fan is pushing air through the system.

If your fan has a broken motor, or dirty blades, this can cause a decrease in airflow that could lead to frozen coils.

  1. Condensate line issues

Condensate lines are the part of your HVAC system that drains away the excess moisture from humidity. This moisture, condensed into water, travels through condensate lines to drain. Lines that are clogged, broken, or do not have the proper pitch, can freeze resulting in ice accumulation. A common place for obstruction happens near the evaporator coil, which is the coldest part of the HVAC.

  1. Malfunctioning thermostats

Your thermostat works with your HVAC by regularly checking the temperature and controlling the amount of conditioned air your building needs to stay at the desired temperature.

If the thermostat is malfunctioning or does not read the correct temperature in the space, it could cause the unit to run longer than needed. Left unchecked, an overworked HVAC unit could develop frozen HVAC coils.

  1. Refrigerant leaks are a common cause for frozen coils

Refrigerant is the chemical that runs through your HVAC coil, it regulates the temperature by absorbing heat inside of the space. When refrigerant leaks, it will affect the cooling process of your HVAC system, which causes condensation on the coil to freeze.

BUILDING AUTOMATION SYSTEMS (BAS) -THE BENEFITS

The benefits of Building Automation Systems (BAS), sometimes referred to as Building Control Systems (Controls), vary, but the reasons usually fall into three main categories:

  1. They save building owners money
  2. They allow building occupants to feel more comfortable and be more productive
  3. They reduce a building’s environmental impact

SAVING MONEY

A Building Automation System can reduce the utility bills for building owners. A more energy efficient building simply costs less to run.

Estimated energy savings from simply monitoring occupancy range from 10-30%, which, based on the size of your building, can create significant savings on utilities each month.

Typically, building owners or facility managers find that the money a BAS saves them can over time offset the installation and implementation of the system itself.

Also, optimizing the operation of the equipment for your facility can extend the life of the equipment, meaning reduced replacement and maintenance costs.

 COMFORT AND PRODUCTIVITY

Efficient control over the building’s internal environment can create a healthier and more pleasant work environment. Furthermore, studies have shown that improved ventilation and air quality can have a direct impact on productivity and a business’s bottom line.

 ENVIRONMENTALLY FRIENDLY

By reducing energy consumption, a BAS can reduce the output of greenhouse gases and improve the building’s indoor air quality, the latter of which ties back into bottom line concerns about occupant productivity.

AVOID FROZEN PIPES IN YOUR COMMERCIAL FACILITY

AVOID FROZEN PIPES IN YOUR COMMERCIAL FACILITY

 

For many building owners and facility managers, frozen pipes can be one of the most significant problems that occur during the cold months.

 

Items that can contribute to frozen pipes:

  • PIPES THAT ARE NOT WELL INSULATED. Insulated pipes keep the warmth in and the cold out. If pipes are not insulated, it is much more likely that the water inside them will freeze.
  • PIPES LOCATED IN NON-CLIMATE CONTROLLED AREAS OF YOUR FACILITY. Commercial buildings may have areas that are not climate controlled or have poor heat distribution.  These areas include basements, exterior walls, or more remote spaces.
  • PIPES FREEZE BECAUSE THERE IS NO WATER CIRCULATION. Water supply lines and drainage pipes can be sensitive to freezing temperatures. These lines/pipes often have water sitting stationary for long periods of time.

 

TIPS TO HELP PREVENT PIPES FROM FREEZING IN YOUR FACILITY

  • INSULATE THE PIPES. Use pre-formed pipe sheaths or wrap the pipes with standard blanket-style insulation.
  • INSULATE THE BUILDING. It is also a good idea to insulate areas that are likely to get cold. Increased insulation can also make your building more energy efficient.
  • USE HEAT TAPES. Heat tapes are lengths of wire with embedded heating elements that warm up to heat pipes.  These can be wrapped around your pipes to prevent freezing.
  • SEAL AIR LEAKS. Make sure to seal any cracks, holes and gaps that allow cold air to blow in on pipes.

ARE MY PIPES HAUNTED?

Squeaking, creaking, vibrating, and banging pipes can make you feel like you are living with ghosts or goblins. However, more than likely…… it is nothing supernatural, but just sounds that could be explained by issues in your water pipes.

 

CREAKING AND TICKING SOUNDS

“Creaking” sounds can be caused by hot water traveling through copper pipes. The hot water causes the pipes to expand causing them to rub against any surface surrounding them.

Once copper pipes begin to cool off, they start to contract and may cause a ticking or creaking sound. A possible resolution to the “Creaking” & “Ticking” noises could be an adjustment to your water temperature or wrapping the pipes to lower or eliminate the sounds.

 

POPPING SOUNDS

Mineral buildup in your water pipes can cause “Popping” sounds. The buildup creates a rough coating on the inside of the pipes, which results in the forming of air bubbles that burst and pop when the water heats up. The source of these “Popping” sounds may be your water heater. A Commercial Plumber will know how to flush your water heater to reduce sediment or can install a new water heater if needed.

 

VIBRATIONS, BANGING, AND CLANGING SOUNDS

A common and easily manageable issue that can contribute to many of the sounds and vibrations in your systems water pipes is water pressure. Loosely attached water pipes sometimes vibrate due to the pressure of traveling water. Pipes that vibrate against solid objects can produce a loud vibrating or knocking sounds.

A sudden banging or clanging throughout your water pipes could be caused by a closed valve that suddenly halts the flow of running water causing a hydraulic shock wave to travel through the pipe until it hits a solid obstacle with a loud bang! A Commercial Plumber could help to solve the issue.

SIGNS OF AN A/C WATER LEAK

Have you found a puddle of water in the mechanical room or notice a wet spot on the ceiling tile?  If so, something is wrong.  Likely, you’re A/C has a leak!  What do you do now??!!

First, don’t hit the panic button!  There are several possible causes for an A/C to leak water and many of them are not a difficult and expensive repair.

However, it is important to act quickly, because a leaking A/C can cause major damage to walls, ceilings, floors, furniture, and could lead to major repairs or equipment replacement.  Proper Preventative Maintenance provided by your trusted Commercial HVAC Service provider can help prevent most of the issues listed below.

 

COMMON REASONS WHY AN A/C MAY LEAK WATER

  1. FROZEN COILS – Probably the most common reason an A/C leaks water. Locate your indoor air handler and look at the evaporator coils. If you see a block of ice, turn the unit off immediately and call your Commercial HVAC professional for a service call.

 

  1. DIRTY COILS – When regular maintenance is neglected, it is common to find dust, grime, and dirt on the A/C coils. The dust, grime, and dirt buildup can impede the flow of water to the drain pan.

 

  1. DAMAGED INSULATION – Insulation on your coils are designed to keep the accumulated condensation flowing down the coil. However, when the insulation gets damaged with cracks or holes, water can drip directly from the coil instead of flowing to the drain pan as it should.

 

  1. DISCONNECTED DRAIN LINE – This problem usually stems from a poor installation. If you’re A/C’s drain line wasn’t attached correctly, it can become disconnected and lead to an A/C water leak.

 

  1. CLOGGED DRAIN LINE OR TRAP – Here is another issue due to lack of maintenance. The condensation collected by your air conditioner carried dust and debris into the drain line and drain pan. This causes the drain line to clog and results in the water to backing up and overflowing/leaking.
