If piping support e g.
Condensate drain pipe slope.
Drain pipe slope calculator.
This type of problem can cause condensate to pool at unwanted locations even if piping is set at a slight inclination so it is important to both.
Using corrosion resistant material and sized no smaller than the drain connection on the appliance.
The following diagram lays out the different terms that are used in the calculator.
He was ignoring the plumbing code 1 8 per foot slope for condensate drain lines and apparently he didn t recognize the potential costs in rot insect damage or mold if we simply let the condensate drain clog due to an improper slope and dust that will enter the line followed by leaks into the building wall up at the air handler.
Set piping support at appropriate intervals and.
The installation of condensate piping shall be as follows.
307 1 condensate drain piping must be corrosion resistant for condensate from fuel burning appliances.
I traced the pipe through the attice and both units go into the large pvc pipe that goes down the wall and up out of the roof to the vent stack.
Imc 307 2 2 tells us that an a c condensate drain inside diameter should not be smaller than 3 4 and should not be smaller than the drain pan outlet diameter.
My a c units drain into a pvc pipe that is tied in to the house s plumbing.
How to use the calculator.
Pipes must slope slightly downhill to drain properly.
Set piping at a slope of no less than 1 in 100.
Pipe hangers is set too far apart the piping can deflect under its own weight.
The standard slope is anywhere from inch to 3 inches per foot.
The drain point must ensure that the condensate can reach the steam trap.
Nowhere to put vacuum to suck out clog.
Slope the drain shall have a slope of not less than 1 8 inch per foot and shall be approved corrosion resistant pipe not less in size than 3 4 of an inch for air cooling coils and not less than the drain outlet size for evaporative coolers or other equipment.
Types sizes slope of condensate drain piping.
3 4 is sufficient for up to 20 tons according to the imc unless the drain outlet size is larger than 3 4.
This drain pipe slope calculator will calculate the slope and total drop fall of a drainage pipe over a specified length of pipe.
A pipe that slopes too much drains water but not solids.
