Be mindful of the lettering on the PVC piping. 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. They simply state that drain systems must be trapped, leaving design to others. Good tips and knowledge. For structures located in flood hazard areas, mechanical systems, equipment and appliances shall be located at or above the elevation required by Section 1612 of the International Building Code for utilities and attendant equipment.

The code book says the size of the pipe is for one or a combination of units, or as recommended by the manufacturer. We live in Texas and I can't find a clear answer on if that is required or not. We have to use certain materials for our piping. Prevent materials from entering and clogging roof drains and conductors and from spilling or migrating onto surfaces of other construction. 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. 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. blown into the unit from the outside and settle in This applies to gravity / natural drain with no condensate pump assistance.

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. Before we worry too much let's find out if there is a concern, that is, is there actually a problem of condensate forming on the outside of the condensate drain line and in sufficient quantity to wet the interior of the return ducts (which isn't a great place to rout pipes of any sort). 801.3.2 Walk-In Coolers. I know I can install a condensate drain with air gap above the sink but it doesn't look very elegant to me. 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. Were required to get a strap on it every four feet. Untreated condensate will perforate copper pipe in 5 months if untreated. Strong . A point I want to make to installers: we can get caught up in this little 6 by 4 area were installing in and not be mindful of the complete drain line. 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. 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. not less than the drain on the unit, and in no case less than 3 4 of an inch (20 mm). 5 Mini-split Accessories Mandated by Building Codes The only code I have found (Oregon) regarding condensate removal is in the mechanical code (which usually applies to HVAC) and this line is making me question whether the pump's output can in fact be less than 3/4": UV resistant wrap for linesets 4.

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. Check it periodically and clean, if necessary." Lets take a look at what the codes say about condensate control and adherence to the code when doing an HVAC change-out. 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.
