i was recently in a car wreck and the airbags went off. i heard you are supposed to throw the clothes you were wearing away. is it safe to continue to wear them?
I'm not sure what kind of water piping you have in your house. If it's copper pipe and the leak is on the actual pipe itself, you can repair the leak with push together fittings (shark bite, pro bite, there are many brands just ask your clerk at your local hardware store). Since this is on your tub I'm guessing this is a half inch pipe and will take 1/2 inch fittings. Most of these fittings have been approved for permanent use and will last years to come. If your piping is galvenized, I would suggest using what is called a pipe repair clamp. This is a stainless steel saddle that has a rubber inside that clamps around the hole in the pipe. This will temporarily fix a leak on a galvenized system and most hardware stores carry these in 4 lengths to 6 lengths. I would strongly suggest having a repipe done with new copper or pex piping as soon as you can. *note* To cut out the hole in a copper system, you will need a copper tubing cutter. These pipes are generally in hard to access places so I would by a very small cutter, often referred to as a thumb cutter. If the leak is on a fitting, you are best to just call your plumber out. Depending on your area, most plumbers can fix easily accessible leaks on copper systems in the ball park of $100. Good luck!
If it's leaking out of the stem packing, you can tighten the packing nut - just a little at a time, and with the valve closed. Anything else and you probably have to replace the valve.
Have you applied concentrated dark matter to the sides yet?
