PVC Bulkhead fittings are often preferred over other fittings such as copper and iron. PVC is preferred because it is corrosion resistant, inexpensive and durable. A PVC bulkhead fitting can be made of any size PVC pipe to fit a wide array of jobs. Almost all hardware stores carry the materials needed to make a PVC bulkhead fitting. Making a bulkhead fitting will take only minutes after all supplies are purchased.
- Skill level:
Things you need
- PVC Conduit coupler, male threaded to slip
- PVC Conduit coupler, female threaded to slip
- Rubber plumbing gasket
- PVC Pipe, 1-inch long
- PVC pipe
- PVC elbow joint
- PVC Glue
Mark the location where the bulkhead fitting will be placed and decide the size of the bulkhead fitting. The size of the bulkhead fitting will be the diameter of the PVC couplers, PVC elbow joint, PVC pipe, gasket and drill bit.
Drill a straight hole through the side of the container the size of the male end of the coupler. If the hole is too large, the coupler will leak. If it is too small, the coupler will not fit. Conduit couplers are used in this project instead of plumbing couplers because plumbing couplers are tapered and conduit couplers are not.
Apply a ring of glue on the coupler where the male threads meet the slip section. This glue will adhere to the side of the container and create a better seal. Screw the male end of the PVC conduit coupler into inside of the hole on the container. Make sure the coupler is inserted all the way and the seal is tight. This leaves the male threads pointing outward.
Slide the rubber gasket over the threads on the male coupler and screw the female coupler over the male threads. Tighten the female coupler as tight as possible.
Place glue around the end of the female coupler where it meets the container to completely seal the area.
Apply a ring of glue around both ends of the one inch PVC pipe and slide the pipe into the slip end of the female coupler.
Slide the PVC elbow over the open end of the PVC pipe and glue it in place. Attach a length of PVC to the open end of the elbow. The total length of this pipe will depend on your specific project. This is the drain pipe and can be any size you wish.
Allow the glue to dry. Most PVC glues dry with in 30 minutes. Always read the instructions on the container to ensure the joints are glued completely.
