- Q: opposed to using copper pipes
- I'm a fan of PexSupply as a distributer; they sell the leading brand of potable water PEX tubing, AquaPEX. Read about Wirsbo's AquaPex at the link below:
- Q: I did this experiment where we added copper strip to cyclohexane solution and another copper strip to water. In water it floated, but in sank in cyclohexane. WHY DID THIS HAPPEN?Something to do with intermolecular forces??Thankss :)
- The 1991 Pittsburgh Penguins and 1993 Montreal Canadiens decided to test its buoyancy by tossing it into Mario Lemieux's and Patrick Roy's respective pools (The Stanley Cup—noted then-Canadiens captain Guy Carbonneau—does not float.). Dominik Ha?ek had his visit with the Cup cut short for doing the same.
- Q: I‘m soldering in some replacement 1/2 shut-off valves in my basement, and the (water soluble) flux and (lead free) solder combo pack I picked up from the home improvement store is exceedingly difficult to work with. The old 50/50 lead solder used to be so easy to use. I‘ve heard that, even with the modern products available - buying higher quality soldering supplies can make this job a lot easier. What‘s the best?
- i always preferred sterling solder and nokorode flux, c-flux is ok, make sure you clean the pipe and fittings
- Q: copper oxide + sulfuric acid > copper sulfateBut copper oxide doesn't contain OH ions??? Then how can it neutralize H ions??
- See my previous answer.
- Q: Is it because it sits in a copper pipe for longer?
- BECAUSE I DID A **** IN IT
- Q: It comes out and goes up into the ceiling next to another pipe. My dad installed a new water heater yesterday and I think he banged it and it is leaking air now. It is a gas furnace and I am afraid now that gas is leaking into the garage. It is not part of the big gas line connected to both the furnace and hot water heater.
- The leaking air you hear is actually the freon in the air conditioning system. It's a very serious problem. Soon your ac will blow warm air, then the compressor is likely to go bad. Asap, call ac company to repair the leak. I suggest the ac to be turned off until the service person come to look at it. Please do it soon.
- Q: has anyone heard of copper pipes in a 4 yr old home having pinholes all through the house? i have already had to replace pipes that leaked and replaced sheetrock and problem still happening
- Gina, one of two things happened. Either the contractor who did the plumbing throughout your home used copper that was very old or the copper that he used, even though it may have been new, was defective. No way copper should be doing that at this point, 30 - 35 years down the road, maybe, now, no way. I'd take them to court. There's no way for you as a homeowner, to know about any of this sort of thing when you have a house built. You have to trust that the guys are doing the job correctly and using proper, NEW materials. More than likely, unless you have all the pipes replaced at once, you'll be fighting this problem as long as you live there.
- Q: GREE's 5 air conditioners are made of copper tubing of various sizes
- Hello, useful 10 and 19, and also 12 and 19, please accept it!
- Q: why they don‘t use aluminium pipes instead of copper pipes in solar water panels?aluminium pipes are more cheaper than copper so why don‘t use them?thank
- Aluminum pipes will react (corrode) with water running through them. Copper doesn't do this.
