Mechanical equipment, appliances and supports that are exposed to wind shall be designed and installed to resist the wind pressures determined in accordance with the International Building Code. This creates a nuisance area of slippery water that, over time, can even start creating algae which are even more slippery. Piping shall be at least 3/4" in diameter and shall not decrease in size [throughout its run from the condensate drain pan to its final disposal destination - no constructions by diameter]" In the City Code, "Mechanical Code" means the 2021 Uniform Mechanical Code adopted in Section 25-12-131 (Uniform Mechanical Code) as amended by Section 25-12-133 .

Untreated condensate will perforate copper pipe in 5 months if untreated. Air conditioner cooling coils require a condensate drain with a trap in accordance with the manufacturer's instructions [2019 CMC 310.1]. You'd fix that by either having your plumber install an appliance wye in the standpipe (I show a typical one - the Canplas 212321W Appliance Wye - as widely sold including at Amazon - below) or by pumping your condensate to another drain destination. Thin aluminum rain gutters were not designed to carry this type of corrosive waste to the ground. This mandatory cleanout allows technicians to blow-out the lines with compressed air at a later date when mold and gunk build up inside it. DO NOT send a larger-diameter condensate drain outlet into a smaller-sized pipe: there's risk of blockage, overflow, etc. Mechanical Engineering. . That helps ensure that that the water properly trips the switch instead of overflowing out of the vent if a backup occurs. We have to use an approved corrosion resistant pipe like Schedule 40 PVC. Recently learned for 5 ton draw-through systems, the 3/4 PVC exiting the coil needs several inches of vertical drop to sufficiently create enough water volume & weight to stop back pressure which clearly created spillage/leakage from the drain pan. If the drain line includes waste from a condensing furnace, it will create a more acidic waste type that needs to make it to the ground. Updated 3/4/2022 Picking up where we left off in part 2 of the series, we discussed how a pressure reading from an attached zone indicates only the ratio of the [], 2023 - HVAC School | All rights reserved. But, what also I noticed was that the primary condensate drain had been capped off with no outlet. No. Equipments 10. In my OPINION citing "code" is a weak argument for not addressing a condensate handling problem **IF** the problem is present or likely and considering that we don't find that requirement in the model codes. PLUMBING CODE MECHANICAL CODE FUEL GAS CODE BUILDING CODE *A newer version of Internet Explorer (v.9+), Firefox (v.25+), Chrome (v.24+) or Safari (v.5+) is required to view these documents. My "guess" is that the reason those pumps are excluded is an effort to avoid leak and mold damage liability. 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. We cannot have condensate runoff drain to public walkways and driveways. So, if we are supposed to drain the primary into the drainage system of the house, can we terminate the drain line over a gutter and let the water fall into the gutter, where it will continue to the ground to an approved area? Make sure that there are no reductions in pipe diameter along the entire run.

An example that you will see in some installation instructions used for equipment that is draining through an appropriately sloped drain line with no trap whatsoever down into a condensate pump that in turn pumps condensate to the disposal point. CMC 310.3 says condensate waste pipes must be made from materials designed to work with that type of condensate drainage. I was afraid that would be the recommendation. Condensate drain hose trap 5. Opening/closing doors and windows can also worsen the issues that stem from infiltration due to upsetting the balance of pressures in the home. If the drain system backs up the there is potential that it can back up into the evap coil. @Sean Marlow, What are the specs of pipe needed to drain 20 units that are all over 3 tons each? Another important topic is covered by the code books and installation manuals for the equipment being installed. Is there an error in this article or am I misunderstanding something? IT couldn't handle the volume, nor the flow rate, nor the duty cycle. About the Business. Notice that one of the most common condensate disposal locations, connection to a plumbing stack vent pipe, is not recommended and is prohibited by building code in some jurisdictions. It's often permitted but not the best solution to simply drip condensate into the laundry sink. They will eventually rust out and create a new problem. The following are significant changes to the IMC and its proposed amendments. The model building codes do not explicitly require insulation on HVACR condensate drain piping, but in some circumstances that insulation might still be recommended or even required by a local code official. Ask the new owner to be more-specific about any damage or problem conditions she's seeing - maybe send along a photo. It may not be defined as a public walkway, but it would still be a nuisance for the homeowner and family members who must walk through that wet spot every day during normal activities. Carson Dunlop Associates sketches (left) illustrate both acceptable and not-recommended locations for the discharge of an air conditioner or heat pump condensate drain line discharge. On 2019-08-05 by (mod) - problems with flexible condensate drains run through walls. From what I can tell, both local code (IPC 2018) and the water heater install guide only say that the condensate line needs an air gap. DavidThe overflow drip pan can be capped off provided that there is a water sensor switch installed that will shut down the AC system if the pan receives condensate water. Both require an air gap - which you have, and neither should be overwhelming a properly-sized, un-blocked drain. Or use the SEARCH BOX found below to Ask a Question or Search InspectApedia.

Plumbing Code (UPC) and the 2005 National Electrical Code." So do let me know if you can find out this detail. Why would we be worried about draining our condensate liquid into the rain gutter? Depending on the actual RH and temperatures involved (and some other factors), that combination may result in sufficient water condensing on the outside of the condensate drain line in that space to cause dripping, wetting, inside the return ducts. It is the final part of his series on zonal pressure diagnostics. 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.
