If you're a staunch do-it-yourselfer, you don't want to scrimp on plumbing tools. Like most every tool in the box, when it comes to plumbing tools I've found that the greater the quality you can afford outright, the less you spend on replacing broken tools. Of course, that doesn't matter when it comes to washers, tape, or o-rings, but why be a cheapskate when it comes to wrenches, saws, and pliers?
I surfed the web to find what other sources consider indispensable plumbing tools. Repair Home lists pipe wrenches, seat wrenches, pipe cutters, plungers, snakes, WD40, and Channel pliers among the must-have gear for working around pipes and water pressure.
Plumber's tape and joint compound are fundamental assets if you have to deal with burst pipes or other plumbing jobs that require attaching pipes. I'd have to say from experience that having a small tackle box of washers, tape, and rings has saved my hide a number of times.
