10 ways to prevent a plumbing nightmare 5. Know the code. Plumbing is a tricky business, with rules that dictate how far you can place a fixture from the homes drain-waste-vent line based on the pipe diameter and other arcane matters. The only way you can handle a big job yourself is to know the code and what it calls for in pipe sizing, fixture spacing and related matters. What to do: Theres lots of reference for ambitious do-it-yourselfers. Buy a copy of the International Plumbing Code or the Uniform Plumbing Code. One of the best references that weve used here over the years is Code Check, a handbook thats updated as building codes are updated. One of its best features is that its written to cover common problems and things that even professionals get wrong. 6. Cut right, fit tight. You cant make a neat water- or gas-tight joint unless the parts are neatly cut. What to do: Buy pro-level tubing cutters, reciprocating-saw blades, hacksaw blades and a plastic pipe saw. For example, youll be amazed by the difference between a professional tubing cutter and the $5 special from the home center. Likewise, it seems silly to spend $20 for a plastic pipe saw when a standard handsaw works pretty well. The thing is, the plastic pipe saw works better and leaves less of a burr, since its teeth have very little set compared with a saw meant for cutting wood. Remove burrs from plastic and copper and thoroughly clean both types of plumbing materials before soldering or gluing. Copper is best abraded with plumbers cloth (aluminum-oxide sandpaper on a spool), and plastic requires material-specific primer that softens the plastic so that the adhesive can create an optimal bond. When pipe feels greasy or dirty, use pipe cleaner before applying primer. A few minutes of preparation go a long way in ensuring a watertight or gas-tight joint.
