How to Make Removable PVC Fittings

Fit the one foot piece of pipe into the coupler and press it in tightly.

Drill a hole through the center of the connection, such that you create a hole straight through both the pipe and the coupler. Be sure to secure the pipe firmly before drilling, to prevent it from turning on you. Preferably, use a vice to do so.

Insert the bolt completely through the hole and lock it in place by attaching the nut on the other side. If you have trouble pushing the bolt through, run the drill bit through the hole a few times to slightly widen it. The bolt will prevent the pieces from being pulled apart, yet will still allow you to disassemble the joint easily.
