Fortunately there's a utility sink directly below it. I know I can install a condensate drain with air gap above the sink but it doesn't look very elegant to me. I wondered if my alternative idea would be an acceptable solution? (You can learn more about the basics of combustion on a podcast with Benoit Mongeau.) And to clarify that, an indirect waste pipe is something upstream of a trap rather than downstream, and this includes the main venting stack as well. Water doesn't flow uphill, and if you tried raising the sides of a condensate pan to get condensate level high enough to drain by gravity alone, you're building a breeding ground for dangerous bacteria or Legionnaire's disease in the condensate that stays in the lower part of the pan. Air Conditioning Condensate Handling defects lead to condensate spillage, leaks, mold. blown into the unit from the outside and settle in For structures located in flood hazard areas, mechanical systems, equipment and appliances shall be located at or above the elevation required by Section 1612 of the International Building Code for utilities and attendant equipment.

Thin aluminum rain gutters were not designed to carry this type of corrosive waste to the ground. The result is the accumulation of dust, debris, algae or mold in a dip in the drain that leads to clogging and potentially to a backup and leak of condensate out at the air handler. Piping that conveys fluids that have a design operating temperature range between 55F (13C) and 105F (41C). Thanks so much for watching and well see you on the next blog! "The information in this guide is a summary of requirements Alternatively, should this line have a vent just after it exits the water heater and possibly a small trap before it joins the main line out to keep insects out? That leaves us a lot of wiggle room for interpretation and a lot of authority to the AHJ (authority having jurisdiction) and design professionals to establish what is and what isn't an approved location. Here are a few good guidelines: IMC 307.2.2 tells us that an A/C condensate drain inside diameter should not be smaller than 3/4 and should not be smaller than the drain pan outlet diameter. My "guess" is that the reason those pumps are excluded is an effort to avoid leak and mold damage liability. Are there currently any plumbing codes that prevent A/C condensate from being used for toilet flushing? In SC, does the condensation line of an attic HVAC unit need to be insulated? This article will dive deeper into the density of standard air [], This article was submitted by Genry Garcia of Comfort Dynamics, Inc. (this is a table of insulation thicknesses that I will post below). That helps ensure that that the water properly trips the switch instead of overflowing out of the vent if a backup occurs. Please take a look. Excerpt: The condensate drain does not require a trap. This creates a nuisance area of slippery water that, over time, can even start creating algae which are even more slippery. Those are not usually very noisy; check for malfunction, for mounting on padding, for alternative models, for relocation to a more remote spot that can still pump up to the necessary drain. Mechanical system piping capable of carrying fluids above 105F (40C), or below 55F (13C) shall be insulated to a minimum of R-2. Trane, our manufacturer recommends one, saying a field fabricated trap is not REQUIRED for proper drainage due to the positive pressure of the furnace; however, it is recommended to prevent efficiency loss of conditioned air.. Because typically the installation instructions for a condensing tankless water heater include this statement: If the condensate lines travel off the service platform and disappear in the insulation, thats fine. 4. overflow of the primary drain pan or blockage of the condensate drain piping. Steam line b. Really? This is just another prime example of how installers can set a system up for success down the road when another technician comes to service it. UV resistant wrap for linesets 4. Unform Plumbing Code. PHMSA notes that during transportation, the gas mixture or its components may partially liquefy, forming condensation on the container wall, if ambient temperatures are lower than 20C (68 F), but still above -50C (-58 F). The full text of the code is available through ICC, and the proposed amendments are available through the North Central Texas Council of Governments (NCTCOG). Solutions often proposed are for a trap of sufficient depth that water in the trap will not evaporate sufficiently to lose the trap seal during periods when no condensate is being produced. Some condensate products might be too hot for the piping used for an HVAC condensate drain - such as that thinwall flexible plastic tubing found at many installations, (condensate from a condensing tankless water heater is at about 38C or about 100F) but standard PVC pipe, if that's what was used for the drain, should be OK. It is the final part of his series on zonal pressure diagnostics. An English company developed a toilet tank several years ago that uses both condensate and potable water for flushing. Air conditioning condensate drain clogging - how to de-clog the A/C condensate line or drain pump. The reference was issued in 2015. I just had a furnace and cooling coil installed in my attic area. On 2020-05-18 by (mod) - overflow drip pan can be capped off provided that there is a water sensor switch. The requirement for the air gap on a dishwasher (you could use the same device) is to prevent accidental siphon of the trap as well as to prevent backflow of drain water into the draining appliance (dishwasher or condensate pump). The condensate drain from mechanical equipment is regulated by the mechanical code. The flood-level rim of the receptor shall be not less than 6 inches (152 mm) lower than the lowest Provided an air vent and drain plug in the coil. CONDENSATE DRAIN INSULATION REQUIREMENTS at InspectApedia.com - online encyclopedia of building & environmental inspection, testing, diagnosis, repair, & problem prevention advice. And the typical application in the install guide only shows this line running to a floor drain, and of course includes an air gap. The picture in the article for a 5 ton system would NOTt be nearly enough to overcome the negative air pressure caused by draw-through air pressure and thus result in coil pan pan spillage. General Electric Zoneline instructions [8][9], Watch out: see the warnings and advice about health hazards in HVAC systems and condensate handling systems, This topic has moved to CONDENSATE DISPOSAL, IMPROPER. Code (IPC), International Mechanical Code (IMC), 2006 Uniform My opinion also is that the cost of tubing or plastic drain lines for a condensate pipe is trivial, just a few dollars, and perhaps not worth your time arguing with your warranty company. Coil shall be tested at 500 psi (35 kg/sq.) Opening/closing doors and windows can also worsen the issues that stem from infiltration due to upsetting the balance of pressures in the home. Mechanical Specification Condensate Trap 2 Nikki Lane Natural Bridge Station, VA 24579 Phone: 540.228.1967 . IMC 307.2.3 states that all HVAC equipment that produces condensate must have either a secondary drain line or a condensate overflow switch, a secondary drain pan with a secondary drain line, a condensate switch, or some combination of these installations should be used to prevent overflow if the primary drain line blocks.
