When trying to locate a plumber, be sure they have had proper training. There are three types of plumbers and they are classified by the amount of training they have. An apprentice plumber receives training through a local union. They follow an apprenticeship program for about three or four years. They learn through on-the-job training and some classroom structure. An apprentice plumber does get paid for on-the-job training.
The next step in this process is to determine what type of method is available for fixing the problem. You cannot just caulk a crack or fill it in with cement and hope for the best.

This takes a professional in most cases to determine the best method for repair.
Here are some general cautions. Do not begin jobs on holidays, weekends, or at times when plumbers raise their rates or are difficult to reach. Do start early leaving plenty of daylight to call a plumber if something goes wrong. Study the situation carefully. Think about what might happen if something suddenly broke and what the effects would be. Old corroded copper tubing might break in the wall when you are wrenching an angle stop that supplies the water line repair to your toilet. A flood in the wall could be costly. If the angle stop, on the other hand, is new and shuts off easily and you have another toilet in the house then it might make sense to repair the toilet yourself. Be honest, too. Are you handy with tools? Did you do well in shop classes in school?
For a newly installed icemaker, you will need up to 24 hours to let the machine function and cool down. A newly installed icemaker may not work until the ice mold temperature has dropped to about 15F - 16F degrees. If you have just added a water line to the refrigerator, it may take up to about an hour and a half for the machine to start working. Also, a newly installed water line may have air in the line. It can sometimes take a few ice making cycles to clear the line of air.
