My OPINION is that the pump itself - the container and motor, sold as a unit - is separable from the drain piping or tubing. This causes smooth inflow of condensate into the container of Acetrap, and causes smooth condensate drain. Where a product has multi speeds, a typical installation has been used for the below calculations. But it’s not. There's a p-trap. [P] 888-ICC-SAFE (888-422-7233) B&G … Connecting a trap to a vertical drain with a wye fitting and a 45-degree elbow seems like a good idea. Only 5 left in stock - order soon. - 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 thermostatic trap is included because it is ideal where there is no choice but to discharge condensate into a flooded return pipe. A condensate tank/feedwater unit is not designed to be pressurized. 6th Floor, Washington, DC 20001 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. Add to Wish List. Not suitable for use with flexible ducting. broad. If the drain line is connected to a plumbing drain leading to sewer it should have a trap and a downhill vent.

Apologies for the delay. 110mm, 125mm and 150mm Condensation Traps, for fitting in vertical rigid PVCu pipe 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. 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. Add to Compare. Carson Dunlop's sketch (left) shows the proper locations for disposal of air conditioner or heat pump condensate. But, what also I noticed was that the primary condensate drain had been capped off with no outlet. Check it periodically and clean, if necessary." This is usually a T-shaped vent which has a PVC cover. The condensate line empties with an airgap into an 1-1/2 trap which tees into the vent stack. Examples of Model Building Codes Condensate Disposal Regulations & Recommendations. Fitted with 20mm pipe connection for running off condensate. 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.In the photo the white flexible condensate drain tubing is being routed down from above where a split system A/C unit is to be hung on the wall. It coats the pan, p-trap and drain piping with a lubricative film to improve flow and prevent future soil adhesion. nuisance." -- [Thanks to Al Carson, Carson Dunlop Associates, Toronto], Note: new in 2015 is the ICC IMC 307.2.5 & IRC M1411.3.3 Drain Line Maintenance code for 2015, The ICC, under "Drain Line Maintenance" requires that, Condensate darins shall be configured to permit the clearing of blockages and performance of maintenance without having to cut the line.

Additionally, the inducer motor would suck air through the drain if it weren’t trapped, which could affect combustion, and would prevent proper drainage. 33822 1301.17.3 Water supply system test. 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. 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. Or should the air handler be seated on rubber be seated on rubber bushings? Not suitable for use with flexible ducting. Calculate estimated running costs for this product using the tool below. Thank you for your help with this matter. Is placing an air handler on top of mason bricks sitting inside the drip tray proper installation procedure? 1301.17.1 Drainage and vent pipe test.

GerardThe manufacturer of your air handler is the final authority on this installation detail but in my OPINION while it's common to see an air handler set into a drain pan on wood and sometimes other materials, a rubber anti-vibration pad would be a better practice for two reasons:1. vibration transmission to the building framing (if the unit is installed on a wood frame floor or ceiling) will make the unit noiser than necessary2. We did not find cleaning requirements for condensate drip trays cited in the model building codes surveyed to date. [10] "Whirlpool WGPH45 Packaged Heat Pump, Product Specifications", Whirlpool Corporation, [copy on file]. Condensate waste water is slightly acidic, and care must be taken as to where it is drained.

When we arrived home we immediatly turned the A/C back down (we had set it high since we werent going to be home). Length: 85mm I saw what the problem was, ( under charged or line blockage). Are there currently any plumbing codes that prevent A/C condensate from being used for toilet flushing? 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. Additionally, the inducer motor would suck air through the drain if it weren’t trapped, which could affect combustion, and would prevent proper drainage. I often find that the flexible condensate drain tubing is not carefully installed nor supported to maintain drainage slope throughout its run. Fitted with 20mm pipe connection for running off condensate. 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. ... P3105.1 Distance of Trap From Vent.

Since the drain taps into the exhaust system, leaving it open to the air would allow for a potential exhaust/flue gas leak in the living space, which is a big no-no. Are these considered the same item or are the pump and lines two different items? 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. Tip for Air Vent If the inlet of A is subjected to a pressure of 7 bar, continuous fine air release at the top of the trap causes differential pressure inside the condensate drain, and the condensate to be drawn into the condensate drain. Remove the cover to access the drain. 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.
