I have to replace the main water shutoff valve for my house. The handle broke off while doing other repairs. It's on a 7/8 inch copper pipe in a hole about 2 feet in the ground. I had to replace another valve in my garage, and used a single cylinder MAPP gas torch to sweat another valve, fitting and pipe together. The temp was around 10 degrees, and the torch didn't seem to put out enough heat to allow the solder to make a complete 360 degree seal on the joint in the sweat valve the first attempt.I have a full size oxy/acetylene welding/cutting/brazing/heating kit. It has a rosebud tip. Can this be used to sweat some of the larger fittings together? The little tank of MAPP gas doesn't seem to put out enough heat for larger pipes and fittings. It seems to do fine for things 1/2 or less.
yes and even faster if it is an older/incandescent bulb you should get a nice LED night light
Typically you will not have to worry about setting off sprinkler systems because they are usually triggered by heat. On many indoor systems you may notice a little glass rod with red liquid in it that looks like a glass thermometer. when these heat up the fluid breaks the glass and the valve opens. However, smoke based fire alarms will go off (as you noticed) but heat based alarms will not.
Sounds like a pretty small business. Yes, they can fire him at will. Have him contact your state's department of labor and ask about any alternatives (such as temporary disability if you state has it).
Yes it can, you should never cover a lamp with flammable materials or anything else. You wouldn't put a blanket over an electric fire, by covering your lamp with clothes you're effectively doing the same thing.
