How to stop plumbing joints from leaking.

How to stop plumbing joints from leaking, this can be an unexpected surprise and you need to know how to fix this situation or prevent it from happening. . Connections using threaded pipes and fittings are at risk of leaking it they do not get sealed with either Teflon pipe joint compound or Teflon tape. That’s why serious plumbers use both of those solutions on each joint they ever work on, as added security. They’re hoping to avoid getting called back in to fix a mistake that they made.

As my friend from Guelph Plumbers would say “do it right the first time, or don’t do it at all.”

How it works. Start by wrapping any male threads with your Teflon tape. Wrap your tape in a clockwise direction. Three layers are typically enough. Every once in a while, a loose fitting that needs more wraps than this will come in front of you, but four or five should be enough. You just have to stretch and then tear the tape to get the wrap done.

Next, get your Teflon pipe joint compound and spread a thin layer of it over the previously applied tape. If a plastic tape is what you’re using, make sure your Teflon pipe joint compound is specifically compatible with it. Start the threads using your hands before you start tightening up the connection using wrenches. Always wipe excess away.

If your compression joints have a ferrule, lubricate it.

Use pipe joint compound to lubricate the brass ring and ferrule.

Shutoff valves commonly have compression joints, but you’ll see them on other fittings too. They typically have a ferrule, a plastic or brass ring, which is compressed in recess when the nut is tightened, this forms a seal. When you use a dab of Teflon pipe joint compound, you can lubricate both the ferrule and the tube. That helps the ferrule slide on the pipe and then squeeze into a tight fit in the recession, so you don’t have to use as much wrench pressure. Use a pair of wrenches to firmly tighten compression fittings so you can crimp any ferrule onto its pipe. Also, be certain that the tube or pipe is straight with the fitting. Leaks happen from misalignments. If your current fitting sports a leak after the water is turned on, try to tighten the nut an extra quarter-turn. That’s usually enough to stop a leak.

Seal and lubricate waste line connections with pipe joint compound.

Joints that come with chrome trap-style assemblies count on rubber-style slip-joint washers for their sealing, but these commonly leak. If a chrome trap is something that you are reassembling, go out and purchase new slip joint nuts and washers. On the other hand, newer washers are prone to sticking to the pipe, which makes them distort or twist as you tighten them with their slip joint nut. If you want to prevent this, lubricate the slip joint and drain tubing with a bit of pipe joint compound. Create yourself a tighter seal and help the washer glide smoothly by doing this.

Start the process of any slip joint nut with your hand, and then twist it into place until you know all the threads are properly engaged. First, tighten all the joints by hand. Then, you can adjust any trap parts until they have alignment with a slight pitch for drainage. That is essential. Any misaligned joint is going to leak, even when you put new washers into the mix. As the last step, use a pair of large slip joint pliers in order to tighten up nuts an extra half turn.

Any plastic trap parts are going to use hard-plastic-made slip joint washers for their seal. Be sure the flat part is up against the nut where the tapered side is facing the right fitting.

Pick supply tubes that are flexible.

You probably want to avoid solid chrome or copper supply lines. They’re hard to get just right without a ton of personal experience.

Supply tubes that are copper or chrome and skinny are often used to connect toilets and faucets, but they are difficult to cut, align, or bend. Fortunately, you don’t have to hassle with them. When you replace a toilet or faucet, go with flexible supply hoses that have braided coverings instead. There are rubber gaskets at both ends, so they don’t need much force for sealing. One trick is purchasing a connector that has the right size nuts for both ends. When you go to the store, take with you the old nuts from both ends and the tubing. That way you can be certain of an exact matching up.

Carefully start the nuts before tightening by hand. After that, tighten an extra half turn, but don’t overtighten. If the joint should leak, just tighten it a bit more.

I hope this helps if you ever come across a leaky joint or need to do a quick DIY project.

I couldn’t find an awesome video so I will probably make one and update this post later.
