Home Plumbing Written Simple

Home plumbing is always a challenge. I included a list of sink drain trap hardware items to buy at your local hardware store, for your added convenience. I explain how to install a heavy duty commercial sink trap in your home. I will explain how to correctly solder joints together. I cover a little on safety from my perspective. You should always read the caution and safety instructions that come with your products.
Safety First
When using a torch be extra careful. Use tin foil and other types of metal to protect your house from catching on fire. Were I can not fit anything I use tin foil to protect the other side of the pipe from catching the house on fire. It is easy to slip a piece of tin foil between your pipe and the house, why take a chance. Newer torch tips that automatically shutoff when you are finished, by releasing the trigger, are sweet.
Hardware Item House Plumbing System Diagram List
Small section (five feet piece) of two inch diameter PVC pipe, two inch diameter PVC trap, two inch diameter PVC male threaded wall soil stack coupling, two inch diameter PVC female threaded drain neck coupling, PVC cement and PVC cleaner, Teflon tape, and saw if you do not have one.
Note: The threaded end diameters of the two couplings will not be the same size as the two inch pipe ends of the PVC coupling. Reduced threaded ends will need to be expected on each coupling. I can not determine this because each house is setup differently. To measure the drain neck diameter, look under the sink across the bottom threaded area of the sink drain pipe, to see how wide the opening is. Now take a ruler and or tape measure, and measure the diameter of the drain pipe, plus include the threads. Take your old soil stack male coupling to your local hardware store for correct match to a new two inch diameter PVC male coupling. Remember that the threaded end might need to be reduced down from two inches to something new.
Sink Trap Installation Instructions
Apply Teflon plumbing tape to PVC soil stack male coupling, drain neck thread pipe, or any other threaded pipe areas, after you preassemble. You need to cut a two diameter PVC pipe that fits between two inch female drain coupling and the trap. Cut another two inch diameter PVC pipe, from the soil stack coupling to the trap. Cut the two inch PVC piping with a hack saw, power hand saw, and preassemble drain to make sure everything fits together. Remove all small PVC burs from cut edges. Then apply the PVC cleaner to the cut pieces. Screw PVC soil stack male coupling in, glue cut PVC pipe piece to PVC two inch male soil stack coupling end, glue one side of the trap to the PVC pipe end. Screw the female PVC coupling end onto the drain, glue the two inch pipe to the female PVC coupling two inch end, and glue the trap end to the pipe end. Align the new trap ends and screw together. Wait fifteen minutes for glue to set, run water to test. I love these heavy duty commercial sink traps, better then the flimsy residential sink traps, sold in the plumbing section of your local hardware store.
Note: Assemble all pieces together before gluing. This is to make sure it all fits together correctly. Make sure the trap fits together nicely together before gluing.
Note: You will need to determine your soil stack coupling and sink drain diameter threaded ends. You can take the soil stack coupling with you in some cases. Bathroom couplings unscrew from the bathroom wall. Kitchen couplings go straight to the floor, usually will take a female connector.
Note: To measure the sink drain thread diameter, look underneath the sink. Use a ruler, and measure the opening of the drain pipe from outside thread to outside thread of drain pipe. If no threads on drain pipe, replace drain in sink. Sink drains unscrew from the bottom, and pop out from the top. Bring your old drain with you to the local hardware store, for correct matching of drainage type. Buy some plumbers putty for drain sink installation. When you install the drain, follow the drain instructions, make a worm out of the plumbers putty, and place it underneath the bottom of the drain that rests in the sink basin. Then install the drain, and screw together the drain.
Soldering Joints Together
Soldering can be intimidating if not done properly. Cleaning the copper pipe and coupling being soldered is very important. I learned how to solder by making a lot of mistakes, meaning I made a lot of scrap pieces throughout the years. The key to soldering a pipe joint is to have no water running through it, obviously, and to heat the joint you are soldering, not the pipe. By doing this, you will draw in the solder, when the pipe reaches the ideal temperature that the solder flows at. Buy a small vise if you do not have one, and practice before actually performing work on your home. Build up your confidence. You can make small little practice valves and connect them outside to your garden hose. Then turn the water on, open the valve to flow water, and close. Check for leaks in your copper plumbing solder connections. With some small sections of half inch copper pipe you can make a few different examples to build your confidences level up. A good torch tip is like halving a helper next to you. Buy a torch tip that automatically turns off when you release the trigger. These are the best and very safe for soldering.
