Sep 6, 2021 · I'm installing a new vanity and found green oxidation at the elbow joints of the copper pipes exiting the wall. As you can see in the pictures below, there is much more oxidation on the hot water pipe (first two pics) than the cold water pipe (third pic). I recently purchased the home and don't know the history of this plumbing.
Nov 29, 2020 · 1. You need to heat the copper to point where it is hot enough to melt the solder. I've had problems using propane torches for this purpose, so bought a Mapp torch. Makes all the difference. Another thing that will impede the heating of the copper pipe is any kind of moisture in the pipe.
You should only use about 1/2" to 3/4" of solder to make a joint on that size; don't add more or you could just fill the pipe. Keep a dry rag to knock off excess solder and a wet rag to cool and clean the joint. Flux causes oxidation (turns green). Don't worry about burning off flux: it will take unless it's too hot.
May 2, 2020 · 1. Copper is corrosion resistant to most materials found around a home ; EXCEPT ammonia and urine ( urea) . Some household cleaners contain ammonia. When moist they cause corrosion of copper. Ammonia and related materials can cause stress corrosion cracking of brasses.That is why brass flex tubes have not been used for decades to connect gas ...
Aug 24, 2021 · 1 Answer. Sorted by: It is best practice to isolate copper from dissimilar metals to prevent galvanic corrosion. This includes hangers and supports. In my area, when copper pipes come in contact with a dissimilar metal we wrap the copper pipe with Polyken 930-35 tape. This is a product designed to provide long term corrosion prevention.
Aug 7, 2012 · You can use silicon to secure the escutcheon to the floor. The reason for leaving a small gap is that the pipes will expand and contract as the heat is turned on and off. The gap will prevent any friction between the two items. If they do rub, you will hear the rubbing every time the pipe changes temperature. Share.
What size is that copper? You can get plastic p-trap kits in 1-1/2" and 1-1/4", and these can be easily connected to your copper via slip ring compression fittings. Basically they consist of a nut with a cone-shaped plastic washer, which when compressed by the nut squeezes against the (copper) pipe to create a seal.
May 9, 2013 · If they are not circular, then even if the ferrules can be forced onto the 1/4" copper pipe, the fitting will leak. If the ferrules do not slip on easily, it might be due to the ends of the 1/4" pipe being out-of-round, or (unlikely) due to defective ferrules. Using a tubing cutter will help ensure the cut ends of the 1/4" copper pipe are circular.
Mar 13, 2019 · By copper pipe, I mean the typical 1/2" and 3/4" copper pipe used in residential plumbing applications. Usually it changhes in thickness: 0,8mm 1mm, 1,2mm, 1,5mm, 1,65mm, 2mm, 2,5mm. Mosto common is 0,8 and 1. There are different grades and types of copper pipe that you of course should be aware of. However I think your question is whether ...
Mar 17, 2015 · Pex and copper have differing inside diameters. Copper has the larger opening. As to 1/2 copper to 3/4 pex I dont know for sure. This said I would not run my hot lines at the larger size as the pipe holds more water and will waste more water waiting for hot or sitting in the pipes cooling.
