How do you unplug a clog in water pipes?

A clog in your "water pipe" probably means sediment is plugging it. Pipes must come apart until the clog is found, then clear pipe or replace that section. If the clog is in your toilet, instead of plunging down, try to put plunger in toilet gently all the way to the bottom, then yank up, causing a suction up instead of down. This will break up clogs faster than the normal way. This also works in sink drains. If it is in your entire system (all drains are clogged or very slow draining), you might have roots or a heavy clog getting into your pipes - you probably have to call for Roto - Rooter, or someone like that. Good luck!
