Know Your Service Line
Below is an illustration to show an example of a water service line. A water service line is divided into two parts. The part that is the Homeowner’s responsibility starts at the service valve, which is near the property line, and goes into the home. The part that is the City’s responsibility is outside of the property line and goes from the service valve out to the water main:
The City is working to ensure that all of the materials in the water system are known, inventoried in our system and up to modern standards. Please take the Service Line Inventory Survey if you haven't done so. The City can help you find out what your service line is made of at no cost to you. To do this we will need to visit your home to inspect the service line where it enters your house near the water meter.
If you want to identify the type of pipe in your plumbing system on your own, here are some helpful tips to assist you:
You will need
- A flashlight
- Magnet
- Flathead screwdriver or coin
What to look for
If your service line curves or has a bulb at the end, your line is likely made of lead.
- Plastic Pipe comes in many colors and will not appear metallic when scraped or attract a magnet
- Copper Pipe will reveal metallic "new penny" color when scraped and will not attract a magnet
- Galvanized Pipe will reveal silver or grey metallic color when scraped and will attract a magnet
- Lead Pipe will reveal silver metallic color when scraped and will not attract a magnet
Flush Service Lines
Plumbing installed prior to 1986 is likely to contain materials that do not meet modern standards for health and safety. Old faucets and fittings, old hot water heaters, galvanized or brass (made prior to 2014) pipe, copper pipe with lead solder and lead service lines are all potential sources of contamination. Reduce exposure by running cold water at the tap for 30 seconds to 3 minutes, until the water feels cooler (this means the water that was standing in the service pipes has cycled through), before using for drinking or cooking. Remove and clean faucet aerators on a regular basis to remove any particles or debris that may have become trapped there.
Water filtration products like reverse osmosis systems and filtered water pitchers are also good solutions for consumers who are concerned about aged plumbing systems in their home. It is important to note that not all filtration systems or filters can remove lead, so consumers should fully evaluate product options before making a selection. Boiling can sanitize water, but it does not remove lead or other particles.
