Overtightening Connections
Overtightening supply tubes, piping and fittings and toilet bolts is the #1 DIYer fault. If you creepo too hard on a galvanized or black pipe, coupling, tee or elbow, you risk neat the plumbing equipment. The crack may not happen right away, but the excessive strength can break the fitting weeks later, causing a alluvion.
Overtightening the plastic fittings on toilet and faucet supply tubes is even more common. It just doesn't take that much torque to seal a supply tube. If you tighten the hex nuts too much, they'll eventually break and leak. Plus, overtightening toilet closet bolts at the flooring or between the bowl and tank can crack the porcelain and destroy the toilet.

Wrapping Thread Tape Backward or Using the Incorrect Tape
PTFE thread tape (commonly called Teflon tape) must wrap clockwise around the threads for it to work properly. But, many DIYers wrap it backward and then the tape really unwinds from the threads as they tighten the fitting. That defeats the whole purpose of using thread tape since information technology tin't seal if it isn't embedded in the threads.
Here's a tip for proper wrapping: Wrap three times around the threads with the terminal wrap facing to the left as you screw the piping into the plumbing fixtures. If that last wrap is pointing to the right, stop and re-wrap it.
Too, use the right tape.
• Use sparse white or thick pink thread record for fittings that carry water.
• Employ yellow gas-rated tape for threaded gas line connections.
• Never utilize thread tape on compression or flare fittings

Using Drain Cleaners as a Beginning Selection
The easiest mode to remove kitchen and bath sink clogs is to utilise a snake or a barbed drain cleaning tool. Or, simply remove the P-trap and cascade out the clog. Simply besides many DIYers attain for the liquid bleed cleaner first and they pour in way more than the recommended amount. That's a mistake because liquid drain cleaner isn't the best choice and more than certainly isn't ameliorate. In fact, liquid bleed cleaner tin can create more problems than it solves. Here'due south why:
• If the liquid cleaner doesn't clear the clog, you or your plumber will probably have to remove the trap arm subsequently on and it'll be filled with caustic corrosive drain cleaner. Won't that exist fun?
• Using too much bleed cleaner, or using it as well oftentimes, can damage metallic traps and pipes, causing leaks.
• Liquid drain cleaner destroys the rubber gasket used in "mission" style couplings. If you have any of those couplings in your drain lines and you lot use liquid bleed cleaners, you lot'll harm them, causing leaks in the futurity.

Tackling a Plumbing Job Without Spare Parts
DIYers often make the mistake of buying just a cartridge or washer for a faucet repair. But if the washer or cartridge are worn, chances are other faucet parts are worn equally well. If you don't replace the stem seal and gasket and O-rings when replacing the washer or cartridge, you'll probably air current up with a leaky faucet. That'll mean a second trip to the hardware store and another faucet disassembly/reassembly. Those peripheral parts are inexpensive, then make it a rule to buy them all upfront and "rebuild the faucet" rather than replacing just a single office.
The aforementioned rule applies when working on drain lines. If y'all'll be disassembling a metal p-trap and arm, make certain you have enough safe compression gaskets to replace the gasket in every articulation y'all disassemble. The beveled poly washers used on PVC traps and arms tin be reused, but yous should still accept a few spares on hand in case yous lose one or discover the old ane is cracked.

Using Too Much Muscle On a Stuck Shut Off Valve
Sink and toilet shut off valves tend to seize when not operated for long periods of time. If yous can't turn the knob by hand, don't think you can solve the problem by applying more muscle. Yous'll non only break off the knob, but you can also intermission off the valve stem at the aforementioned fourth dimension. The trouble is that the stalk packing seal has welded itself to the valve stalk, preventing information technology from turning. The fix is use an adjustable wrench to loosen the stalk nut just enough to break the bond so you can turn the knob. When you're washed, only snug up the stem nut and brand sure there's no leak.

When you turn on the water, you lot'll see fine jets of water shooting out of the joint. Then you'll have to redo the entire job. The solution is to plug the pipe with white bread, a special capsule-similar plug or a special tool before hitting the joint with a torch. Become a soldering expert with these tips.

You can prevent that kind of damage by ownership an inexpensive gear up of internal pipe wrenches. The same advice applies to other plumbing repairs.

This setup may look okay, only it'south a lawmaking violation that can cause real problems. Equally it sits, the bleed water will menstruum so fast down the steep slope that information technology tin siphon h2o out of the p-trap, allowing sewer gas to enter the house. In other words, this setup really stinks. The DIYer should accept used a sanitary tee in this application. Yet, you lot can't use a sanitary tee in all drain applications. Y'all tin't apply it to connect two horizontal pipes or a vertical pipage to a horizontal drain. Different situations call for a tee, wye or a long or brusk sweep elbow. Plus, you tin can't apply 90-degree vent elbow to change management in a drain line (unless you really similar cleaning out clogs).

Since they're often installed in out-of-the-way places, the leak tin go unnoticed for months, causing mold problems. Toss the saddle valve and install a ball valve instead.
