Drain line blockage troubleshooting !By Imran

Blockages in the AC Drain Line

1. Turn HVAC system off. 2. Locate cleaning port. If the unit has turned off due to a blockage, you may need a bucket to collect the condensation resting in the drain pan. 3. Remove cleaning port cap. 4. Assess clog. If you can see the blockage, attempt to remove the blockage. Do not push it further away. Instead, attempt to lift the blockage out of the drain pipe. If the blockage breaks, separates and falls down the pipe do not be alarmed. It can be rinsed out with water. 5. Slowly pour cleaning solution down PVC drain line. If cleaning solution fills drain line, do not continue to pour solution. Follow steps in Method 2. 6. After pouring is complete, assess the blockage. If the cleaning solution does not flow out of the drain line, the blockage is still intact. This may be a sign that there is a larger block in the drain line. Follow steps in Method 2. If the pipe fills and slowly drains then repeat step 5 until cleaning solution passes without difficulty. 7. Replace cleaning port cap. 8. Turn system back on.
