Does AC condensate line need a trap?
There are some simple ways you can tell if the drain line in your house is being run and draining correctly. First, the coil that your primary drain line is running off of needs to be at a downward angle allowing the water from the coil to drip into the drain line. Every drain line also needs a “P-Trap”.
Do you need P-trap with condensate pump?
Yes, if the pipe extends below the water line inside of a pump, that is a trap and yes, if someone adds another trap it won’t work very good. Also, the furnace has a built in condensate trap inside of it, so you need to be aware of that too.
What is the purpose of the P-trap in a condensate line?
The same thing applies to our air conditioner, but in our case, the purpose of the P-Trap is to prevent outside air from being drawn through the A/C unit. The weight of the water in the trap is enough to prevent this, while still allowing condensation to flow freely.
How do you trap a condensate drain?
Quote from the video:
Quote from Youtube video: And this trap has water right in the bottom here. So we're going to go ahead and see what. Happens. So now it's allowing all the condensate. In this pan to drain out properly.
Should the condensate trap be full of water?
The boiler should never be operated without the condensate trap in place, as it prevents noxious combustion gases from travelling down the condensate pipe. Should the trap have to be removed from the boiler, it must be topped up with water when it’s replaced.
How deep should the condensate drain trap be?
If a unit were to be operating at minus 6 inches WC maximum negative plenum pressure then the trap height, per the guidelines shown in Figure 1a, requires 7 + 3½ + 1½ + 1 inches of height from under the floor or about 13 inches below the floor level.
Does a furnace need a condensate trap?
The condensate trap is absolutely mandatory for a high-efficiency gas furnace. 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.
