Specialty plumbing tools are sometimes expensive—even to rent—and are mostly there for the "pros."
But the average Joe (or Jane), however, can buy or rent many of them at the big box retailers, plumbing supply houses or tool rentals, but its intimidating when you don't know exactly what you need.
Salespeople are mostly knowledgeable and happy explain the uses and functions of their specialty plumbing tools. Assuming you are allowed by the building department in your jurisdiction to work on your plumbing (check first) these "professional" tools are available to, and most are operable by, the general public.
Most homeowners call a plumber in a panic when something goes wrong. If its a broken water line, you may feel there's no other option. But, if you'll just shut off the water and take a deep breath, you might decide differently. A calm attitude and a close inspection could create a situation in which you become a plumbing hero!
There are 3 basic types of plumbing problems; LEAKS, DRIPS and CLOGS.
First, assess the problem. If its a leak, see if you can shut off only the pipe that's supplying the leak. If its a clogged drain, decide if you can do without that particular appliance or fixture until you can fix it. If its a drip, you're going to need a few parts. In any event, grab a pad of paper and write down and/or draw anything that might be important—ie. size, material, brand name, specifics of the problem, etc.
Block out some time and go talk to someone at a big box retailer, plumbing supply store or even your local hardware store. Get two opinions if you can. Once you feel confident with understanding the "what" and "how", you'll know which way to proceed.
Hey, you might just need a plumber after all. But if not, and you believe you can do the job yourself, you'll proceed knowing you're hundreds or thousands of dollars ahead!
There are so many specialty plumbing tools it would be nearly impossible to list them all. But you don't need to know all that. You just need to understand the one(s) that will help you now.
Search "your problem" (ie: clogged floor drain, broken copper pipe, galvanized fitting leak, etc.) or "type of tool" (ie: auger, pipe threader, water ram, etc., if known) using the Google Custom Search Box (right) for more information on your particular issue before heading out.
