Q: We are remodeling a 60 year old house. We have changed wiring, sheetrock, insulation, some walls, and now its time to look into plumbing. The house currently has iron pipes throughout, and I figured they should be changed??? They weren‘t leaking when we started, but after breaking some pipes while trying to loosen them, I assume I need to just go ahead and put all new pipes in. Which brings me to my question, what should I put in it? We live in Tennessee, and all these pipes are in a basement, which is not heated, but I‘m not too concerned about freezing, (they obviously haven‘t for 60 years). So, what should I do? I want to do it right, but not spend too much on it, as we have sank a lot of money into other projects. Also, we have a well, not city water (if that makes a difference). Thanks in advance for your help!: PEX is a lot easier to use on a retrofit because you don't have to prepare and solder joints every time you need to make a bend like you do with copper. If you do use copper and are unable to get every single piece of iron pipe out of the walls keep in mind that you need a brass fitting in between the copper and iron, otherwise the copper will get eaten up by dielectric corrosion. I used all copper in the house I built and it was extremely labor-intensive, a lot new construction nowadays uses PEX because it goes in 10 times faster and there haven't seemed to be many problems with it. There was some question about whether PEX would hold up to chlorinated water over the long term because it's similar to polybutylene, which is the gray plastic pipe that was widely used in the 1980's and turned out to be a disaster because chlorinated water attacked and rotted it. Since you are on a well, you wouldn't have to worry about it, and so far the PEX seems to be holding up. As far as PVC is concerned if you go that route keep in mind that standard Schedule 40 PVC is not rated for use on hot water, you have to use CPVC. If the cost between PEX and copper is about the same, I would use PEX because it will save you a bundle of time.

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?: Get a gasfitter at least answer that, if not do the work, to local codes, and have it inspected. Probably black pipe or corrugated stainless.

Q: electrolyttic copper used in cable industry --- price/tonne: Copper is traded on the Commodity Market, and therefore, the price changes daily. The price of copper is predicted to fall during 2007 to something like US$7,700 per metric ton while its peak price in 2006 (May) was US$8,800 per ton. This is due to output growth of copper-concentrate ore, the main raw material for producing electrolytic copper. You may also have to consider the Futures Market, say 3 months out, which may well be lower than today's price. If you need precise daily figures, you need to sign up to one of those commodity news services.

Q: I burned copper (wool) [ 49.34 g] for a certain amount of time, and its color changed; (copper oxide formed)but the mass is still 49.34 g!! Why?: CuO is not copper burnt with oxygen. It's a chemical reaction in which pure copper is oxidized: 2Cu + O2 --> 2CuO Assuming 1 gram of copper is allowed to oxidize... more than 1 gram of CuO will be produced if you do the stoichiometry calculations.

Q: I heard it was from the last one. How much should I use to ask for it?: The central air conditioning refrigerant pipe does not need to calculate the pipe diameter, and the pipe joint size is limited at the factory equipment joint. Wind system only need to calculate the diameter of the pipe.The wind system is the assumption that the flow velocity range according to GB standards, to assume a wind speed of V, and then through the air as is known, then according to the wind pipe area (3600* = air / wind duct area that is assumed), and then to check the information, the wind pipe what size can be selected, 0.23 is that before the wind area, then you can choose a 500*500 wind pipe, this pipe is 0.25 of the area, then put 0.25 into the formula: = air / wind speed (wind area *3600), namely: V= / air (0.25*3600), can be calculated by 500*500 tube after wind velocity.Finally, the pipe diameter is the diameter of the preliminary design under the premise that the actual flow rate meets the specifications. Of course, the calculation needs to be checked later.Seek acceptance as a satisfactory answer.

Q: Is it because moisture or minerals trickle down from the hot water line where it is not protected by the concrete and plastic sleeve?What about the premise that copper corrosion is caused by minerals and/or ph imbalance from anywhere under the slab, which would seem to make any section of copper pipe susceptible?: the original copper loops had hard plastic pipe protecting the copper it has now degredated to whatever the plumber feels like! water heater supply pipes have a die-electric union, they may be getting grounded by the gas lines combined with the heating more electrolisys is taking place, probably eve more so on electric heaters. ( good guess )?

Q: I need a cheap Heater guard. My plecos are getting burnt and i need to come up with a way to shield them off without contaminating the tank. What materials would work?I already checked stores, the only guard i could find was a reptile heater with a pre- attached guard on it. $44.95 for that .I need help in the next hour or so . Please give as much input as you can. thanks.: If you make your own heater guard, use PVC plastic pipe, not the ABS because the ABS has a lower melting point. There are aquarium decorations with holes for a heater. Most look like some variation on a tree trunk. Copper is toxic to fish and aquatic invertebrates. The guard not only protects the fish from burns, but protects the heater from rocks and overactive fish who might start pushing it around. If there are fish clubs around you, they usually have auctions. I have gotten a box of fish tank decorations, including a few heater guards, for as little as a buck!

Q: It is no secret that copper thieves are stealing all and I mean all the copper out of This country. Now we have to have copper for electric lights,electric motors and running water to name a few. It is clear that these thieves are not just poor people out to make a few bucks. The scope of this problem indicates it is very organized, either it is organized crime or people stealing to finance terrorism. The problem is our Law enforcement people are not doing anything to stop the proplem so who is holding them back and why?: LOL Dam that was funny. You throw out several accusations there with out supporting facts. You are making it sound like these 'organized' groups are going to houses and taking the copper right from gramma's sinks. Let me clue you in on something. The majority who think there is 'actual' money verses the trouble in copper are usually meth addicts and I have never seen an organized meth addict.
