Q:I noticed a crack in small copper pipe that runs from the Fuel Oil tank to the furnace. Please help me with an easy repair so that I can get my heat turned back on.: Turn off the oil supply to the furnace, and cut into the line with a junior hacksaw. Then fit a straigh compression connector between the 2 ends. Just remove any burr on the pipe before you fit the connector. takes about 15 minutes.

Q:For our physics class I need to make an instrument, but we need to be able to predict the frequency (note) that the instrument will make before building it. I think that I am going to make a wind chime out of copper pipe. I have no idea how to calculate the length of the pipe that would be needed to produce a certain note. How would I go about this?: You can simulate your metal pipe using Solidworks, and it can compute the resonant frequency for you. Steel gives a better sound than copper, btw.

Q:i need a catchy slogan for copper (the element): Here are some articles that discuss the details of slogan writing. Why certain slogans work and why some don't. You will find these helpful in writing a new slogan.

Q:Should I replace my main water line pipe with plastic (black well pipe) or with a copper?: When you find out the price of the copper it might make up your mind for you. The guy who did my new well used a type of plastic pipe that is blue, very heavy duty.

Q:I have a friend who has a home that has copper plumbing. The residence was built in 1988, and she was told by a neighbor that copper plumbing is bad and has to be removed/replaced in order to keep the value of the home for resale. This doesn‘t seem to make sense and the home DOES NOT have any plumbing issues to date. The neighbor cautioned that copper plumbing can burst. Is there any ring of truth to this or is the neighbor thinking of something else. A home built in 1988 doesn‘t seem that old to me. Please help. All answers are welcome. Thanks.: Copper plumbing is the best available way to deliver fresh water to a home. I read an answer that stated you should have die electric couplings between to 2 different types of metal and that is 100 % correct. A home built in 1988 would not be at risk of lead contamination since the laws changed in 1976 to protect us from such risk. There are still some concerns about a pipe bursting and it is possible not probable. If the home has slab floors it is possible for the pipes to bend or move with settling. This is rare but it does happen. Another way for the pipes to fail would be if one of the solder joints works loose. This is possible if the pipes are not secured as directed in the UPC ( uniform plumbing code ) You would have a warning before they actually fail. If when you use the hot or cold water from any of the sinks or tubs even the washing machine you hear a rattling noise then you may have a problem. I must agree with the general census that the neighbor is confused. I am a licensed plumber in California and one of my better sales points is that copper pipes will increase the value of the home.

Q:why is the copper gone up in value how much is a pound of copper worth.: Its worth around 7500 $ per ton. 1 ton =2200 pounds. About 3.4 $ pr pound. Emerging economies like china/India creates a bigger demand than we can supply

Q:Freon refrigeration effect of air conditioning is related to the length of copper pipe?: It matters；Normally, the air conditioner has a standard pipe length. In this standard pipe length, the refrigerating capacity of the air conditioner is not less than 95% of the nominal capacity of the air conditioner (as stipulated by the GB);When the tube variable length when connecting internal and external machine, a refrigerant flow in the tube resistance (pressure loss) becomes larger, the compressor output variation, on the other hand, long after the loss of cooling capacity of copper copper itself becomes large, air conditioning cooling effect to indirect marketing.

Q:what is the current rate for copper I have a bunch of copper pipe I need to take in!!!!!!!: I'm thinking you'll get around $5.00 a pound for it. But you should be able to look up a recycler in your area and get a quote on line!

Q:(this is the continuation of the question) without cracking.PLEASE EXPLAIN WHY THE SOLDER IN THE PIPES IN A CENTRAL HEATING SYSTEM MUST BE ABLE TO STRETCH.: Copper expands and contracts with temperature change. Solder will also expand and contract but it does not fatigue.
