There are a couple of different methods you can try, but most individuals tend to use a hammer. In plumbing a plumbing tape is used to make the seal stronger and therefore prevent any water from leaking in the pipes. Occasionally even soldering is a method used to weld the pipes together to be stronger. With soldering one will have to undo it with heat. When it has not been soldered, then a hammer may do the trick.
- Hammer
- Plastic Piping
Plastic piping is a lot different than using copper or other metal piping. Plastic such as PVC is delicate. It can get stuck really well when discussing fittings, but you cannot always use a hammer evenly on the pipe as it could cause damage. With plastic fittings you are better off to use muscle with a twisting motion. In effect you are putting a couple of different forces on the pipe. In one way you are using pure brawn to get the pipe loose and in another you are using what could be considered a fulcrum, meaning you are placing a different force on the pipe to get it to loosen. A twist and muscle can take a few moments but eventually it will loosen enough to come apart.
