No. DariaI want to help but am stymied: the decision to include or not the actual drain line as part of the condensate pump system is going to be in the tiny mind and hands of the insurance company's adjuster department. Hey, so we recently brought a house in MA and have come across this: the HVAC is connected to a standpipe for a washer via a tube. Thats pretty much common sense, right? 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. [8] "GE Zoneline Owners Manual and Installation Instructions, Heat/Cool Model 2900, Heat Pump Model 3900", General Electric Corporation, [copy on file].

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. 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.

The result can be wet, moldy A/C insulation, increasing A/C operating cost and leading to a costly mold cleanup and duct re-insulating job. The model same model building codes contain these very minimal requirements for traps on condensate removal lines for HVAC equipment: 1. a trap shall be installed in accordance with the unit manufacturer's installation and operating instructions, 2. the condensate drain line slope towards its final drainage point shall be at 1/8" per foot [or, of course greater, where vertical drains are used - Ed.]. Lets take a look at what the codes say about condensate control and adherence to the code when doing an HVAC change-out. I would think you need to look at the bigger picture as to where the condensate drain is connected. When a drain line is PVC, the IMC dictates that it should be supported every 4 when horizontal (while maintaining proper pitch) and every 10 vertically. We did not discover this until we brought a washer. You need to use a dry-trap such as the Des Champs HVAC Air-Trap in order for this arrangement to work properly. The secondary drain had a wet switch installed in the outlet port. When it comes to the mechanical code, there is no "nationally adopted code," but most states and localities adopt the International Mechanical Code (IMC). When its required by the manufacturers installation instructions, Sacramento area county inspectors look for a trap. 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. 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..

Thats the most popular type of piping HVAC installers use today, but we can also use ABS, cast iron, or hard drawn copper. The NZ Metal Roof and Wall Cladding Code of Practice is a comprehensive design & installation guide, and a recognised related document for Acceptable Solution E2/AS1 of the NZ Building Code. Think of it as similar to a dishwasher installation. Some home inspectors and HVACR technicians want the drain to be insulated either to cure an actual observed wetting problem OR because they're making their own, probably unnecessary, interpretation of one of the model energy codes. 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. f.

In particular, when an air conditioner is shut down for long periods of time (say during the heating season) it is common for the water condensate contents of the trap to dry out, thus losing protection against sewer gas leaks backing up through that system. For example: "In some installations, dirt or other debris may be Its also possible that this install is totally legit, and the air gap requirement is fulfilled by the gap between the ground and the down pipe outside the house.

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. 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. That HVAC drain runs right beneath where the water heater is hanging, and the water heater condensate line is now hard-piped straight down and into the line so that the condensate runs outside without a trap or vent.
