Generally 3/4” is standard but if the water is kept clean and there is enough slope a smaller pipe can be used but the smaller you go the slimmer the margin for error.
What size is AC condensate pipe?

What size are air conditioner pipes?
The larger pipe is known as the suction line, and includes insulation. The diameter on the liquid line for standard residential systems is 3/8 inches in diameter. The suction line diameter is normally either 3/4, 7/8 or 1 1/8 inches, it depends on the size (and efficiency) of the air conditioning system or heat pump.
What type of piping do we use for condensate drains?
PVC piping systems are recognized as acceptable for use in condensate drain systems in all major model plumbing codes.
What size are condensate lines?
2 requires that an air conditioning condensate drain inside diameter should not be smaller than ¾ inch and should not be smaller than the drain pan outlet diameter. Three-quarters of an inch is sufficient for up to 20 tons according to the IMC unless the drain outlet size is larger than ¾-inch.
What size PVC is used for AC drain line?
The termination of the condensate drain pipe shall connect indirectly to the drywell drain pipe. The drywell drain pipe to be a minimum of 1-1/2” PVC or other approved material. Drywell to be at least three feet away from the building structure or any footings.
How do you measure condensate drains?
Multiply the air conditioner’s flow rate, measured in gallons per minute, by the air’s specific humidity, measured in pounds of water per pound of dry air. If 12 gallons flow through the unit per minute, and the air has a specific humidity of 0.0065 pounds of water per pound of dry air: 12 x 0.0065 = 0.078.
Where is condensate drain line?
Your air conditioner has a condensate drain line that runs from the indoor unit to the outside of your home. You’ll find a white PVC or copper pipe located near your outdoor unit—this is where the drain line ends.
What material is used for air conditioning drain lines?
Enter the condensate line, which essentially functions as a drain line. Condensate lines are typically made of plastic (commonly PVC) or sometimes metal, although plastic is prefered. It connects directly to the HVAC unit and leads outdoors, often through an exterior wall.
What size is #10 AC hose?

How do you measure AC copper pipe?
Refrigeration tubing is measured by it’s outside diameter or O.D.: ¼, ½, 5/8, ¾, 7/8, 1-1/8, 1-3/8, 1-5/8, etc. Plumbing tubing is measured by it’s inside diameter or I.D. : 1/8, ¼, ½, ¾, 1, 1-1/4, 1-1/2, 1-3/4,etc.
What diameter condensate line is typically run from the drain pan of the evaporator?
The condensate line from the drain pan of the evaporator is normally: 3/4 in PVC.
Can you use CPVC for condensate drain?
2 Drain pipe materials and sizes. Components of the condensate disposal system shall be cast iron, galvanized steel, copper, cross-linked polyethylene, polybutylene, polyethylene, ABS, CPVC, or PVC pipe or tubing. All components shall be selected for the pressure and temperature rating of the installation.
Can you use PEX for condensate?
You could use PEX tubing or Vinyl, but you need to make sure that it does not get kinked in any way and that it has a large enough ID to accomadate the flow of water or you will be asking for trouble. Also make sure that you are allowed to tie into the main drain line.
How do you measure condensate load?
A rule of thumb to quickly calculate condensate load is: “1000 BTU’s in a pound of steam”. This is not exactly accurate, but is arithmetically easy to use for the calculations of load.
Can you drain AC condensate into sewer?
Should you be worried about an AC condensate drain into the sewer? A simple answer would be yes. An AC condensate line should never connect to sewage directly. This lets the sewage air enter your AC system.
How much does 3/4 PVC pipe cost?
3/4 Inch UPVC Pipe, 3 m at Rs 90/piece | UPVC Pipe | ID: 10997535112.
How long can a condensate pipe be?
The external pipe run should be kept as short as possible to a maximum of 3 metres, taking the most direct and “most vertical” route to the discharge point, with no horizontal sections in which condensate might collect.
How far can you run a condensate line?
Generally speaking, linesets (the refrigerant lines) should be under 50 feet for best performance.
How much condensate does a 3 ton air conditioner produce?
A general rule of thumb is that . 1 to . 3 gallons of condensate is produced for every ton-hour.
How deep should a 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.
How many Btus does it take to condense water?
When one pound of water boils or evaporates, it absorbs 970 BTU’s at a constant temperature of 212° F. (at sea level) and to condense one pound of steam to water 970 BTU’s must be extracted from it.
Should AC drain line have water in it?
The condensate line should drain to the outdoors and during humid weather you should see plenty of water dripping from it. If it’s not dripping, it’s not draining! If there is standing water in the drain pan, your condensate drain is clogged!Aug 14, 2018.
