Only a Certified BFPD Tester is allowed to test BFPD. The Utilities Department does not require any specific individual or company to test BFPD; our only requirement is that the tester be certified. We do have a list of Certified Testers available "solely for the convenience of our customers" of individuals and companies providing this service in the County. The department urges our customers to shop for the lowest price.

When your Backflow was installed it was tested prior to plumbing inspection, but because of the volume of Backflow preventers being installed and the large number of existing Backflow preventers in various lower mainland cities it is not easy for municipalities to keep you informed of when your Backflow is due to be tested. However, due to increased awareness of the importance of protecting our water many cities are taking better steps to inform people when their annual test is due. See similar questions...

The faucets in a home's kitchen, bathrooms, laundry areas and exterior hose bibbs provide what is know as "potable water". Potable water is defined as "fit for human consumption." Non drinking irrigation water is usually termed "non-potable". Both get their water from the same supply line - that is, the local water company's water meter located on your lot.

Answer: A backflow device is installed in order to prevent backflow into the water distribution system. Said device is a mechanical plumbing device made up of two shut-off valves, two check valves, and four test-cocks. The particular type of device depends on the degree of hazard (i.e., extreme, moderate, or low hazard). See similar questions...

There are many reasons why the Port Washington Water District requires a backflow prevention device. The most common type is a Double Check Valve (DCV). All residences with underground sprinkler systems must have a DCV backflow prevention device. The DCV is designed to contain water within your sprinkler system, which protects the public water supply from any backflow contamination. All installed back-flow devices must be inspected annually by law, by a Certified Back-Flow Tester. See similar questions...

All irrigation systems, including residential, connected to the potable water supply are required to have a backflow prevention device (BFPD). The type of device ranges from an atmospheric vacuum breaker to a reduced pressure zone BFPD depending on the degree of hazard posed by the irrigation system. These BFPD do fall under the annual testing requirement. See similar questions...

Does anyone in your household have a compromised immune system (chemotherapy, transplant patient, HIV) that would require drinking water of a higher quality than is required by the general public? For more information, call the EPA Hotline 1-800-426-4791. Are you concerned with taste, odor, appearance, chlorine content, high mineral content (total dissolved solids, TDS), or hardness only?

If you are connected to a municipal supply, call the water Superintendent, or City Hall. They can either provide the answer, or direct you to the proper individual. Remember the conversion factor: it takes 17.1 PPM to equal 1 GPG. In other words, if your water has 171 PPM calcium in it, divide 171 by 17.1 to get the answer in grains. This example would be 10 grains, or GPG. See similar questions...

Generally not, as testing can be expensive. However, having your water tested will tell you whether there are unacceptably high levels of any tested contaminant. Laboratories that test water samples are listed in the Yellow Pages under "Laboratories - Analytical". The lab you choose should be certified by CDPH's Environmental Laboratory Accreditation Program -- be sure to ask. See similar questions...
