For the secondary drain system he installed a wet switch within the pan below the unit which will turn the unit off upon water detection. Also known as thermostatic steam traps, these vent cool air and condensate to increase energy efficiency in your steam lines. Air Admittance Valves (aka Studor vents) are “negative-pressure-activated” one-way mechanical valves. A/C condensate drains & pumps: codes, installation, leaks, clogs, connections, troubleshooting & repair: This article discusses the inspection and repair or un-clogging of condensate disposal systems, including air conditioning, heat pump or condensing boiler/furnace condensate drains & condensate pumps, and their proper installation as part of our review of condensate piping, traps, drains, Air-conditioning condensate waste pipes shall connect indirectly to the drainage system through an airgap or airbreak to a properly trapped and vented receptors dry wells, leach pits, or the tailpiece of plumbing fixtures. from the 2003, 2006 and 2009 International Residential Code Condensate drain lines are commonly tied to vents and/or drains. 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. Are these considered the same item or are the pump and lines two different items? If the drain line is connected to a plumbing drain leading to sewer it should have a trap and a downhill vent.

The subject of steam trapping is dealt with in detail in the Block 11, ‘Steam Trapping’. It coats the pan, p-trap and drain piping with a lubricative film to improve flow and prevent future soil adhesion. Reader Question: 7 Feb 2015 Diane S said:In SC, does the condensation line of an attic HVAC unit need to be insulated? For simplicity, the maximum distance between a trap and its protecting vent has been presented in the form of a table for decades. B&G … Section 407.2.4, Traps, requires that "Condensate drains shall be trapped as - ICC IMC 307.2.5 & IRC M1411.3.3 Drain Line Maintenance code for 2015, original source: http://www.iccsafe.org/, Devices or methods for providing condensate drain cleaning or de-clogging are discussed in this companion article: CONDENSATE DRAIN CLEAN & DE-CLOG, The following HVACR condensate disposal recommendations summary cites, paraphrases, & comments on the widely adopted 2006 ICC model building code section on condensate disposal, section 307 [7], For the two Types of Condensate: Fuel burning devices vs Evaporators & cooling coils. ! The vent is also where the air in the steam system leaves. Condensate or wastewater shall not drain over a public way. 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. Air conditioning condensate drain clogging - how to de-clog the A/C condensate line or drain pump. A 80 % furnaces makes no condensate thus the trap becomes a dry trap in the heat season. Not suitable for use with flexible ducting. 1301.17.3 Water supply system test. We have no relationship with advertisers, products, or services discussed at this website. In the drain line, the condensate and any incondensable gases must flow from the drain outlet of the plant to the steam trap. P-traps have to be installed on a suction system, so a p-trap was added. Add to Wish List. Code (IPC), International Mechanical Code (IMC), 2006 Uniform That means we cannot dump into anything downstream of a trap. The vent ensures that the tank does not see pressure. I don’t look codes up but for the past 51 years you have never been able to connect a condensate drain to a vent stack unless the trap is a wet trap which means there must be a liquid seal in the trap 365. Not suitable for use with flexible ducting. It appears that this condensate drain only drops into that vertical standpipe an inch or two and if there is still a decent opening around it to let air into the standing drain line then you got an air gap between the end of the condensate drain and the P-trap below so it should be okay. Remove the cover to access the drain. Steam traps used to drain condensate from steam mains, are shown in Figure 10.3.14. I worry about relying on the condensate pump and flexible tubing as the primary drain source vs. a hard piped system into the homes plumbing.

Features & Benefits: 307.2.3 recommends any of the following methods for handling a backup condensate overflow protection system: Section 307.2.3.1 requires use of a water-level monitoring device to provide condensate overflow protection on equipment where there is no secondary condensate drain and no ability to install an auxiliary condensate drain pan. For average costs, leave the default values in place or enter your own figures in the boxes to recalculate. Watch out: in our OPINION and as we discuss in these articles, while a trap on a condensate drain line, usually provided quite close to the condensate collection pan itself, can reduce the chances of sewer gases backing up from a condensate drain that has been connected to the building DWV vent piping (not a procedure we recommend), a conventional P-trap in the condensate drain will not protect against all … 150mm Condensation trap, for fitting in vertical rigid PVCu pipe ducting. closet.

However a read of manufacturer's installation instructions can provide further advice. Puerto Rico and the U.S. Virgin Islands enforce one or more of the I-Codes. My "guess" is that the reason those pumps are excluded is an effort to avoid leak and mold damage liability. 110mm, 125mm and 150mm Condensation Traps, for fitting in vertical rigid PVCu pipe ducting. The section of the code that pertains to the maximum trap-arm (also called a “dirty arm”) length has strict provisions designed to prevent a siphon from forming in a drain. I inspected a home earlier today and they had the AC condensate drainage into the (previous) laundry drainage. As water drains down the steep slope at the wye, it can create a siphon effect such that water will be sucked out of the trap. Air vents are particularly important when equipment configuration causes air build-up or when the capacity of the air venting function of a steam trap is insufficient (i.e. The secondary drain had a wet switch installed in the outlet port. In a properly sized drain line, the plant being drained and the body of the steam trap are virtually at the same pressure and, because of this, condensate does not flash in this line.
