Q: I would like to change my propane grill over to natural gas. I know I will need to change the orifice in the grill, no problem with that. And I have done quite a bit of gas work as a plumbers apprentice many many years ago. I have worked with both black pipe and copper inside walls and in crawl spaces. I have plenty of access and can easily T off my water heater with 1/2”. Planning on installing a shut off at the T and another at the grill end of the line, about 12 feet of run, all above ground and run along the outside of the home roughly 8” above ground just below the vinyl siding. Question: Today what are the pros and cons of copper and black pipe in this application?: sure you can use copper but i suggest you use soft copper and flare fittings

Q: I just installed a shower mixing valve and all of the soldered connections were fine. However, there is a slight leak at each of the copper to brass threaded connections into the mixing valve. I was only able to tightend the copper fitting a certain amount in order to achieve the proper alignment of the copper to copper piping. Is there a fix without removing the entire assembly and starting from scratch?: Although you used Teflon tape, you may not have applied it correctly. You have to apply it in the direction that the pipe will be turned. Having the pipe only half way into the fitting will cause a leak. You need to remove the mixer valve and fit the pipe into it before it is fixed to the shower wall. To make sure you do not crush the pipe when tightening, Turn the mixer valve and not the pipe. If you have to cut the pipe to remove it, you can rejoin it by using a slip coupler which will need soldering.

Q: What temperature does coppper need to be heated in order to sweat the pipe?: only hot enough to melt the solder. It's reflective heat that your concerned about, not the actual temperature of the pipe

Q: Line of fire water in unit 140 of phases of gas 1516 in iran use a copper pipe: You don't say where you live. Hostas need shade and cooler temperatures(don't do well in phoenix) Petunias also are not good for heat tolerant. They do need sun but not full sun someplace like phoenix.

Q: We did this experiment in my chemistry class the other day.we had:Solid copper(II)sulfate pentahydrate + fire. What is the product??CuSO4·5H2O(s) + O2(g) --&gt; ????P.S. please balance the equation: Copper Pentahydrate

Q: Wilsons disease, you can't have copper or it will destroy your liver. What about everyone else, will copper hurt the liver and cause disfunction?: iVE HEARD IT FROM PLUMBERS, & KNEW ONE THAT JUST DIED OF LIVER CANCER.... THE OLD PLUMBERS GOT IT FROM LEAD. CPVC IS THE NEW NORM.

Q: plumbing: Oxidation of copper will produce the blue green patina cupreous oxide. It is rust only on copper. Clean it with steel wool or a fine grit sand paper an application of a light machine oil wiped on then off should reduce a chance of recurrence.

Q: What instruments do you have in a brass tube?: Cornet (Cornet)Cornet sound soft, full of singing, but not brilliant. The structure is composed of three parts: mouth, tube and machinery. The length of 1.335 meters, the mechanical part is composed of a piston and a piston sleeve, the piston is connected by pressing the bypass pipe to extend the pipe to no.. Material: copper tube.Is a small deformation instrument cornet, usually used for marching band and dance band, rarely for orchestra. In addition to E flat cornet, use less.
