Whether its to support the drain line with hangars, or to strap it down to the deck, we dont want the PVC to bow downwards, creating a dip and not allowing gravity to do its thing. It should be stated and restated that codes and code enforcement vary from location to location within the US. When doing load calculations (Manual J), we need to know how much of the heat load, especially the latent heat load, comes from leakage in the building envelope and the ducts. . The sink will be used daily so there's little chance for the water to evaporate and allow for sewer gases. 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. DO NOT send a larger-diameter condensate drain outlet into a smaller-sized pipe: there's risk of blockage, overflow, etc. When it comes to the mechanical code, there is no "nationally adopted code," but most states and localities adopt the International Mechanical Code (IMC). Learn how your comment data is processed. Tanks 11. The closest to building code specifications that you will get for the question you post is the general requirement to install materials following the manufacturer's instructions. 4. For walk-in coolers, floor drains shall be permitted to be connected to a separate drainage line discharging into an outside receptor. Uniform Mechanical Code. Energy code: Section 503.2.8 Piping insulation.

Neutralize the Condensate: Most plumbing codes require - Saniflo Thats the most popular type of piping HVAC installers use today, but we can also use ABS, cast iron, or hard drawn copper. 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]" They both say pretty much the same thing. On 2022-06-02 Whats pictured is a clean out with the cap missing. I have to imagine that with A/C being so much more common in the US, the only reason something similar hasn't been developed or adapted for use here is because it isn't allowed. We did not find cleaning requirements for condensate drip trays cited in the model building codes surveyed to date. Since there is a lot of room for inaccuracy in extreme climates (especially those with high latent loads), many HVAC systems are oversized and underperform. Sabik 500 | MVHR System | EnviroVent what is connection from the evaporator condensate pan to the pvc drain line and what is the material required? cooling coil or fuel-fired appliance that produces condensate: 1. My unit was cycling on and off even though it never reached the temperature setting on the thermostat, I suspect this was the wet switch's doing, On 2020-09-09 by (mod) - terminate a condensate line from an interior air handler to a washer stand pipe, Can you terminate a condensate line from an interior air handler to a washer stand pipe. Roof Drainage Terminology. Air conditioning condensate drain clogging - how to de-clog the A/C condensate line or drain pump. by InspectApedia (mod) - condensation has been leaking from the drip pan. Carson Dunlop's sketch (left) shows the proper locations for disposal of air conditioner or heat pump condensate. We did not discover this until we brought a washer. Theres less busyness going on in the scene. Little touches like this can make the difference between a clean install and an average install. . Diane, If your condensate line is not leaking but you are seeing condensation on its exterior such that the exterior moisture is enough to cause damage, then as good condensate drain installation practice that means you would insulate the line. The conventional gas-fueled tankless water heater produces hot exhaust that also contains acidic moisture from the combustion process, and has to be vented through a corrosion-resistant chimney. Does anyone have any information about this topic? Kelli I need to understand more details of the situation - but in general the answer is sure - properly-connected. Above: Table 503.2.8 Minimum Pipe Insulation Thickness, adapted from the 2010 New York State Energy Conservation Code.

Need code reference for AC condensate drain line - Inspecting HVAC Apologies for the delay. This way my line set can be routed hidden up into the attic above and run to an adjacent wall which is exterior and pass through to the outside. 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. a conventional P-trap in the condensate drain will not protect against all sewer gas backup possibilities. Thermal Insulation and . Venting after the trap (like shown on the EZ Trap above) is an excellent idea in most applications because it helps prevent airlock that can occur due to double traps and shared drains. Table 307.2.2 states: "3/4 up to 20 tons" Is this the same code you are referencing? We have to use an approved corrosion resistant pipe like Schedule 40 PVC. The red oval and line mark a critical point where nail plates must be installed to protect the drain line from puncture by future drywall screws or nails. Thanks, Genry! Im not sure if this is relevant to the answer, but the water heater has a neutralizer built in so that shouldnt be an issue either way. Equipments 10.

Please find your question repeated along with a detailed reply now at mechanical service equipment; electrical components; automotive; domestic refrigeration; . This applies to gravity / natural drain with no condensate pump assistance. The black tubing in the photo is actually foam insulated refrigerant piping. Naturally this type of installation precludes running the condensate drain up with the line-set. You will not receive a notification when a response to your question has been posted. Can I use a little giant type condensate pump with 3/4 into the pump, and 3/8 out of it? But you still need to confirm to yourself that the ENTIRE drain line has at least, an eighth-inch slope to it. We have to use certain materials for our piping. Untreated condensate will perforate copper pipe in 5 months if untreated. Your condensate line, also known as a "condensate drain line" or "condensate drain" does several jobs, but none are more critical to the functionality of your appliance than draining excess moisture outside of your home.
