1. Prepare tools and materials. You need to prepare a PVC pipe (the diameter should match the air conditioning interface), a cutting tool (such as a saw or pipe cutter) and a water pipe connector.
2. Find the drain inside the air conditioner. Usually this drain is at the bottom of the air conditioner, which may be different for different brands and models.
3. Make sure that the water pipe needs to be connected to the drain pipe. Ensure that the length of the water pipe is appropriate, neither too long nor too short. If it is too long, it will hinder the water flow, and if it is too short, it will leak.
4. cut off the water pipe. Use a pipe cutter or saw to cut the PVC pipe into proper length. Ensure that both ends of the pipeline are smooth and free of burrs and cracks.
5. Connect the water pipes. Insert the PVC pipe into the air-conditioning drain pipe, and then fix the water pipe on the air-conditioning drain pipe with the water pipe joint. Ensure that the water pipe connector is closely connected with the drain pipe.
6. Test the water flow. Ensure that water can flow into the water pipe smoothly when the air conditioner is running. If the water flow is not smooth, it is necessary to re-check whether the water pipe connection is loose or whether there are other problems.
7. clean it up. After the water pipes are connected, wipe off the water drops on the surface of the water pipes and air conditioners with a cloth or paper towel.
