DiversiTech Wet Switch Drain Pan Overflow Switch

Flood switch. A solid state control designed to help prevent flooding, damage to carpets, walls, furniture, ceilings, etc. now has a built-in test and reset button for easier installation. Turns system off when detecting moisture due to condensate or drain leaks. One or two drops will cause Wet Switch to turn off a unit, alerting a serviceman to a moisture problem.


  • A must-have safety feature
  • Integral Feet - Integral feet raise the hydrophilic pad and sensor array off the drain pan slightly to prevent nuisance tripping and pan corrosion (metal pans only) from interfering with the sensor array
  • Hydrophilic Pad - A high tech polymeric fiber quickly draws water into the sensor array using proven capillary technology
  • Multiple Unit Connectivity - Multiple unit connectivity allows for multiple Wet Switches to be connected in series to adequately cover large drain pan areas
  • Standard 24AC Control - Power supply to the Wet Switch® is 24VAC, the standard power available on most air handler units. This makes hookup quick and easy. There is no need to run different power to the switch.
  • Double Throw Relay - The double throw relay allows for wiring to interrupt the system and to sound an alarm (by others) when moisture is detected
  • Solid State Electronics - Proven electronics prevent mechanical failure in an aggressive operating environment
  • Push to Test - The push to test button on Wet Switch® gives the installer a quick, easy way to test the wiring on their installation. Giving you the confidence the switch will work as designed, when needed.
  • Compact Package - This technology is packed into a hockey puck sized 3-5/8″ diameter by 1-1/4″ high cylinder. Furnished complete with 5-conductor 22AWG stranded cable, 6′ long.
  • Prevents expensive water damage and dangerous electrical situations by adding another layer of protection
  • Our Emergency Drain Pan Overflow Switch shuts off your heating and cooling system if water fills the emergency drain pan.

"Low Level" Carbon Monoxide Health Monitor

Carbon monoxide. The CO EXPERTS model 2016 is considered by many one of the industries best "Low-Level" Carbon Monoxide Health monitors available to the consumer today. Its unique style allows for either wall mounting or portable use with the included free-standing attachment, and with a simple slide and click of its rear mounting plate the "sealed" lithium battery is engaged, ending your worries about replacing any batteries over the course of the units life.


  • 7 PPM - 50 PPM displays current real time CO levels constantly
  • Over 50 PPM display reads "HI"

How much carbon monoxide (CO) is too much?
Bob Dwyer, Director or Training; COSA (Carbon Monoxide Safety Association) "Every day is a carbon monoxide safety day!"The health effects can vary significantly due to age, sex, weight and overall state of health. U.L. 2034 Listed alarms do not give enough protection from chronic harmful levels of carbon monoxide. CO is measured in Parts Per Million or PPM; out of a million molecules of air, how many are carbon monoxide. The items listed with the symptoms in the chart below are for healthy people unless otherwise stated.

12,000 PPM - Death within 1-3 minutes
1,600 PPM - Nausea within 20 minutes, death within 1 hour
800 PPM - Nausea and convulsions - death within 2 hours
400 PPM - Frontal headaches within 1-2 hours; life threatening within 3 hours; UL 2034 alarms should sound within 4 and 15 minutes.
200 PPM - NIOSH (National Institute for Occupational Safety & Health Administration) A worker will not be exposed to more than this amount.
150 PPM - UL 2034 Listed alarms must respond within a range of 10 to 60 minutes if this concentration or higher is present.
70 PPM - If CO at this level for 60 minutes up to 4 hours, UL 2034 alarm should be sounding
50 PPM - Maximum average level for continuous exposure in an 8 hour workday per federal law, U.S. OSHA.
36-99 PPM - Excessive levels with foreseeable health hazards. Suggest a medical alert and health consultant especially if levels displayed are chronic conditions. Advise use of air packs. Ventilation required and source discovery testing is recommended.
35 PPM - 8 hour exposure TWA (time weighted average); NIOSHA (National Institute of Occupational Safety and Health Administration) of the CDC (Center for Disease Control).
25-35 PPM - Levels where fire department personnel wear breathing apparatus. Fire department begin evacuation of buildings at this level.
10-35 PPM - Marginal - Small children, elderly, and those suffering respiratory or heart problems are cautioned if these are chronic exposures concentrations. May increase heart stresses. COSA (Carbon Monoxide Safety Association) approved alarms & monitors begin alarming no later than within these concentration levels.
25 PPM - 8 hour TWA limit; ACGIH (American Conference of Governmental Industrial Hygienists)
9 PPM - Average concentration often measured around busy city streets & intersections.
1-9 PPM - It may be difficult to avoid those often occurring spikes in transient or chronic CO levels without life-style changes.

What are the symptoms of CO poisoning? Consult with your physician!

Carbon monoxide poisoning mimics many common illnesses, such as the flu and food poisoning. The following is a list of common symptoms:

  • Headaches
  • Disorientation
  • Depression
  • Loss of hearing
  • Respiratory failure
  • Dizziness
  • Loss of consciousness
  • Weakness
  • Muscle aches & soreness
  • Blurry vision
  • Painful discomfort
  • Memory disorders
  • Cardiac arrest
  • Repaid heartbeat
  • Nausea
  • Seizures
  • Vomiting
  • Coma

This list is not meant to serve as a diagnosis of carbon monoxide poisoning. It is meant to provide general information on poisoning symptoms. Oxidative stress causes a chain reaction in the body due to the interruption of oxygen intake and is most often not explored by the medical community though they may be presented with the symptoms many times every day. Carbon monoxide poisoning is best treated with supplemental oxygen or pressurized oxygen in a hyperbaric chamber where CO is forced out of the hemoglobin of the blood. The longer CO stays in the body, the more disruption in body functions and symptoms are likely. Carbon monoxide alarms can begin protection at levels that will protect more people more often; the current U.L. 2034 standard does not.

Attic Tent

Attic tent. The HVAC systems in homes are designed for a closed envelope making air balancing with supply and return air, very critical. Every time these systems are operating they create a positive or negative pressure, thus forcing conditioned air out or drawing outside air in the home.
