# How to Connect the PVC Pipe on an Air Conditioner's P-Trap to the Sink
Air-conditioning units create a lot of condensation that has to go somewhere. One of the simplest and most effective ways of disposing of this is to connect your AC unit's condensate outlet to the drainage system of your house via the trap beneath your sink. If you already have a P-trap fitted to your condensate outlet to stop unpleasant odors backing up, it's just a case of extending piping to your sink trap.

- Straight and curved PVC pipe
- PVC pipe connectors
- Sink trap with inlet

Attach a length of PVC pipe to the outlet of your air conditioner's P-trap with a pipe connector. Then, run multiple lengths of pipe from your air conditioner's condensate outlet to your sink, using connectors to join them.

Connect a length of rubber drainage hose to the end of your PVC piping when you've reached the area under your sink. Use a hose clamp to secure it into position.

Attach the other end of the rubber drainage hose to the inlet of your sink's trap. Again, use a hose clamp to lock it in place. Cut the hose to the correct length with a pair of scissors if necessary.
