I don't quite understand the last suggestion - perhaps you could make a sketch. Need code reference. For those pump purposes, no condensate removal pump would be suitable. Untreated condensate will perforate copper pipe in 5 months if untreated. Originally, I think the builder had connected the drain pan on the left direct to the drain outlet, but the pan is lower than the outlet. Air entering or leaving an HVAC unit via the condensate drain line manifests itself as an energy loss and a . Code requires that the condensate be connected to the building drain though an air gap connection and NOT physical to the drain. You will not receive a notification when a response to your question has been posted. The water heater condensate line is 3/4 and so is the existing HVAC condensate line, so maybe that needs to be replaced with 1 at the very least. Is this an acceptable form of condensate drainage? Mechanical system piping capable of carrying fluids above 105F (40C) or below 55F (13C) shall be insulated to a minimum of R-3. Connection of condensate waste to sanitary plumbing and drainage systems This technical note provides clarification on the requirements for connecting condensate from refrigerated air conditioners, cabinets, sterilizers, autoclaves and similar appliances to sanitary or drainage systems. 1. vibration transmission to the building framing (if the unit is installed on a wood frame floor or ceiling) will make the unit noisier than necessary2. 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? Only the discharge of the condensate is regulated by the plumbing code, not the connection of the piping to the mechanical equipment. 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. Thanks, Michael! 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. 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. Thats why we call it a gravity drain because as long as we have the necessary 1/8 inch of downward slope for every 12 inches of carry, gravity will do all the work and pull the condensate waste to the ground all by itself. For walk-in coolers, floor drains shall be permitted to be connected to a separate drainage line discharging into an outside receptor. Condensate waste and drain line size shall be not less than 3/4-inch (nominal) diameter from the drain pan connection to the place of condensate disposal. Loose earth free from rocks, broken concrete and frozen chunks shall be placed in the trench in 6-inch (152 mm) layers and tamped in place until the crown of the pipe is covered by 12 inches (305 mm) of tamped earth. 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. Air Conditioning Condensate Handling defects lead to condensate spillage, leaks, mold. Does Texas code require an attic AC drip pan to be be attached to a drain line or is it acceptable for the drain line to be capped off? 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. Bob,In new HVAC condensate drain installation when the drain is run through framed walls, use of a flexible plastic drain line is common - as shown in the photo I'll attach below and as is described further at inspectapedia.com/aircond/Condensate_Drain_Problems.phpHowever in my OPINION a better installation uses rigid PVC pipe, properly sloped 1/8" to 1/4" per foot. Naturally this type of installation precludes running the condensate drain up with the line-set. Thank u. by (mod) - is condensate drain piping insulation required? So my idea is to install a 3/4" PVC pipe vertically inside the wall and connect it at the top and bottom with 5/8" adapters.

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). But a trap at the heater is probably required. 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. The problem is the water from condensation has been leaking from the drip pan. The IMC code doesn't directly state that the drain line must be insulated. Condensate from air-cooling coils, condensing appliances, and the over-flow from evaporative coolers and . This includes rooftop units, ductless units, and downflow units, but the code does allow for the overflow prevention switch to be placed in the primary drain pan in these cases but NOT the primary drain line, according to 307.2.3.1.
