The IMC (International Mechanical Code) is one of the most widely utilized and referenced. We have no relationship with advertisers, products, or services discussed at this website. 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. . 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. ASHRAE Standard 90.1-2010, Section 6.4.4.1 HVAC System Pipe Insulation, lists HVAC piping requirements and as an EXCEPTION, The condensate line material: Sch. Materials 10. Any suggestion. Piping that conveys fluids that have not been heated or cooled through the use of fossil fuels or electric power. controllers; . Thank you for the discussion. conveyed from the drain pan outlet to an approved place of disposal. Building & mechanical codes do not require insulation on A/C condensate drains, based on a reading of the current U.S. Energy Code that I will excerpt here. Condensate drain hose trap 5. I recently had a condensing tankless water heater installed Im trying to determine the proper way to deal with condensate. Add bevels on most PVC glued joints and some sizes of bell and gasket joints. I have found and will cite the sources of installation instructions prescribing locating the effect condensate drain trap quite distant from the appliance itself. I think the builder cramped as much into that small space to save money. Delivery times . But I hope this answers some questions you have about the building code, HVAC installations, and condensate drain lines. Potentially the largest coordination item between the mechanical and plumbing disciplines is the requirement for drains. If the manufacturer requires a trap, then a trap is required. See also INSULATION R-VALUES & PROPERTIES.
Gasoline transfer pump IRG BGLB 200-250B (179/14), 11kW, 1480 Ex what is connection from the evaporator condensate pan to the pvc drain line and what is the material required? Really? For other readers: what's the difference between a conventional tankless water heater and a condensing tankless water heater? Enter the email address you signed up with and we'll email you a reset link.
310.1 Condensate Drains: Understanding the Codes 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. So "loud" perhaps you are talking about a condensate pump that collects condensate from a heat pump or high efficiency heating appliance and pumps it up to a drain. Energy code: Section 503.2.8 Piping insulation. 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.
2021 INTERNATIONAL MECHANICAL CODE SIGNIFICANT CHANGES - McKinney, Texas c . broad. Condensate or waste water shall not drain over a public way. The code as it relates to condensate disposal in the IMC is pretty vague.
What's a Condensate Line, and Why Is It Important? (CMC 312.1) 2. 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? I inspected a home earlier today and they had the AC condensate drainage into the (previous) laundry drainage. These pipe bevelers are used on PVC and CPVC plastic pipe including C900, Corzan CPVC, Bionax PVCO (C909) and also ABS. While venting is a common best practice, it isn't part of the IMC code. f. Drain Pan - Shall be of sufficient size to catch all condensation from any part of the unit. Our recommended books about building & mechanical systems design, inspection, problem diagnosis, and repair, and about indoor environment and IAQ testing, diagnosis, and cleanup are at the. 2019 CALIFORNIA MECHANICAL CODE RESIDENTIAL CONDENSATE DISPOSAL REQUIREMENTS . When the AC condensate drain entry point is higher than the condensate drip pan outlet you have to either use a condensate pump - which is what I'd do - or disassemble and re-install the whole AC/Heat system to raise it so that it can drain by gravity. Certainly there is no conceptual constraint on where a condensate drain can be located, but it has to be in a location that works either by gravity or by a condensate drain pump. Where pipe insulation is required the requirement depends on pipe size, use, and temperatures that will be encountered.
Chapter 307.2.2 Drain pipe materials and sizes ( 2012 Mechanical Code) states: Where the drain pipes from more than one unit are manifolded together for condensate drainage, the pipe or tubing shall be sized in accordance with Table 307.2.2. Roof Drainage Terminology. 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. Both require an air gap - which you have, and neither should be overwhelming a properly-sized, un-blocked drain. Quoting, Also see: specific condensate drain installations for your specific air conditioner, heat pump, or condensing gas furnace.

CONDENSATE DRAINS, CODES at InspectApedia.com - online encyclopedia of building & environmental inspection, testing, diagnosis, repair, & problem prevention advice. Excerpt: The condensate drain does not require a trap. Mechanical Specification Condensate Trap 2 Nikki Lane Natural Bridge Station, VA 24579 Phone: 540.228.1967 . Thats the most popular type of piping HVAC installers use today, but we can also use ABS, cast iron, or hard drawn copper. And I see far too many systems without a cleanout on them. This creates a nuisance area of slippery water that, over time, can even start creating algae which are even more slippery. Apologies for the delay. Equipments 10. The complex is now owned by a new owner and he has contacted us about why we didn't insulate the condensate drain lines that are inside the return air in an air conditioned space. In mechanical rooms, insulation will prevent any sweating . But a trap at the heater is probably required. And that piping needs to have a certain slope to it.
IP Enclosures IP-GRPDD084 CONDENSATE DRAIN | Kempston Controls Neutralize the Condensate: Most plumbing codes require - Saniflo --- If discharged into the drainage system equipment shall drain by means of an indirect waste pipe. This would allow me to run from the hall where the unit and 11' ceiling is to areas where the ceiling is 10' and continue to where drain terminates. Steam trap c.Steam Loop d. Steam tap. I'm still searching for a check valve that only allows the water to run down and put but stops potential gases from migrating up as a backup but so far no luck. We have to use an approved corrosion resistant pipe like Schedule 40 PVC. The most recent code is the International Mechanical Code (IMC). We make a three-inch hole in the sidewalk and bore all the way through the 4 to 6 inches of concrete and fill it with pea gravel. On 2019-08-05 by (mod) - problems with flexible condensate drains run through walls. Above: Table 503.2.8 Minimum Pipe Insulation Thickness, adapted from the 2010 New York State Energy Conservation Code. . Were required to get a strap on it every four feet. 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. All piping serving as part of a heating or cooling system shall be thermally insulated in accordance with Table 503.2.8. Above on this page, and in the list of Recommended Articles found just at the article end, you will find our series of detailed articles specifying condensate drain piping and routing, requirements for a trap, the materials, and they drain condensate destination.
