Attic Ac Condensate Drain Line

My goal was to piece together a new drain line and use some clear flexible tubing to recreate the trap.

Attic ac condensate drain line.

When everything is working properly condensation runs down the drain line and exits outside your house. Find the condensate pan. So now with all this dirt collecting up and mixing with the condensate line water from your ac you find your air conditioning drain pipe blocked. This helps ensure that if a backup occurs that the water properly trips the switch instead of overflowing out of the vent.

Most but not all ac units will have an easy to locate access point to the drain line. Find the condensate drain line and drain line access point. Look for white pvc pipe around 3 4 inch 1 9 cm in diameter coming out of your ac system s indoor unit. If there is standing water in the condensate pan your drain line is probably clogged.

For furnaces in the attic there is a second condensate drain pan. The trap would collect any gunk and adjustable clamps would allow access for cleaning. This is in place as an added layer of protection against water damage. The vent opening should always rise above the trip level of the condensate overflow switch when it is in the primary drain line or pan or above the secondary aux overflow port on the primary drain pan.

Pour a gallon of water slowly into the overflow pan under the air handler and observe the water level in the pan to verify that water drains freely into the secondary drain line. Look for an upside down or sideways t shape of pvc pipe with a removable cap. But that drain line is pretty small so it doesn t take much for it to become clogged. It may be covered by a removable access panel.

It s usually better to replace the entire drain pan rather than trying to fix it. Sediment algae mold and insects can all clog it up. You can do this project too if you find your air conditioner giving out due to a condensation line clog. Then the clogged ac drain line starts to cut off.

Because entire central air system is lying on its side in the event of condensate drain pan failure water does not drip in one general location. If there is condensate in the overflow pan you probably have drain line clog.
