I was doing some plumbing work this weekend, soldering copper pipe and fittings, and all the dry ones went well. But I had problems every time I had to solder a fitting onto a pipe that had water in it. It would just boil the water inside and never get hot enough to make a good solder connection. How do professional plumbers get around this problem?
Talk to someone from your local deaf association. They might be able to get you the alarms for the deaf..they work like a strobe light and yes they will wake you up..there is different placement for them, so this route might work for you and for the family member whose hearing aid is not compatible with the alarms..but..please..till then put the batteries back in..you can take the batteries out when cooking or put a fan on to dissipate the heat, but please do not go to sleep without the protection of an alarm for the safety of you and your loved ones.
In 42 years of driving in winter country, I have never used chains. Thay are only for temporary use, and are usually mandated for mountain passes at certain times, not for everyday driving. Studs are illegal after a certain date each year because of road wear, and can only be put in brand new winter tires that have the spots for them. The are great on ice, but do nothing in snow. The newest generation of winter tires is great in snow and ice without studs. At the very least, you should have good all-season tires with the Ms designation. I bet you have summer touring tires on your car, and the Vibe has a fairly wide tire for the size of the car, making touring tires dangerous in winter conditions. See a reputable tire dealer about good winter tires for all 4 wheels, or at least an upgrade to good all-seasons.
