A water pipe is any pipe that requires water and separate components or accessories to function properly. Most water pipes feature a base, a tube, and a mouthpiece, with a removable bowl that fits a joint set into the base. Smoke from the bowl enters the pipe through its base and is filtered through the pipe's water. The pipe's tube often features a splashguard to prevent the water from exiting the mouthpiece during use, or a perc to filter the smoke even further. From there, the smoke exits the mouthpiece cleaner than it entered the pipe, making the hits smoother and healthier to inhale.
