To find a plumber to install shutoff valves ask friends and neighbors for a referral, use the Yellow Pages or an online contractor referral service. Another option is to buy the valves at a home or kitchen/bath center where an installation service is offered. Usually there is a tag indicating "installed price". Most stores offer the traditional cash-and-carry price as well as the installed price that covers installation. The retailer arranges for a plumber to do the installation and is responsible for both scheduling the job and of course, your satisfaction.

Here are the basic points that should be included in a written contract with a plumber:

• Description of the work to be completed with a detailed list of the materials to be used
• Cost of material and all warranties from the manufacturer
• Cost of labor and amount of deposit, if required
• Job installation date
