Backflow Testing FAQs
What is backflow testing for?
Backflow testing is a procedure used to ensure that your plumbing system is not contaminating your drinking water supply with unclean water that has infiltrated the system.
It is common practice to keep the water pressure in your home constant to flow from one location to another, such as from the shower to the toilet to the sink. Contaminated water might enter the system if the pipes suddenly lose pressure due to bursting or freezing or because of unusually high water demand.
What is involved in a backflow test?
The real test can begin after the formalities are completed. Tests are performed for two major reasons: to see any backflow and figure out what’s causing it. Backflow testing devices have valves called the gate and relief valves that are used in the testing process.
The plumber will primarily stop valves and monitor gauge movement, water leaks, and other telltale symptoms of trouble before leaving the job.
Specific requirements must be met during the testing procedure. One must make certain that the backflow prevention check valves are effective while keeping an eye on the airport’s opening times. Lastly, a safety measure ensures that pressure between check valves does not drop below 2 PSL before the relief valve opens.
Backflow tests require no special preparation on the part of the property owner. To simplify and speed up the procedure, they should let everyone know that the water will be switched off for a period and that they should make alternative plans for water use or accomplish the duties in advance.
Is backflow testing necessary?
In the long run, backflow protection devices can be a lifesaver. It would be best if you had your backflow checked yearly because of this. Backflow testing is a vital element of your home maintenance schedule to ensure that the water you and your family drink is clean and safe.
Contact Hawthorne Plumbing, Heating & Cooling for backflow testing. When they arrive, they’ll do an inspection and backflow test on your house to ensure the water is flowing properly. We care about the quality of your drinking water.
From the source to your tap, drinking water is pumped under pressure through a series of water faucets. It moves in one direction most of the time, but “backflow” (moving in the opposite way) can occur. Backflow occurs when water flows in the opposite direction via a water system. Drinking this water is dangerous since it could contaminate the public water supply. It’s impossible to know when backflow will occur because of a water main break or heavy demand at a hydrant, thus testing is required.
How often is backflow testing required?
The frequency with which a backflow preventer must be tested is determined by its type. Backflow preventers can be divided into two categories based on the type of maintenance they require. Generally, commercial facilities use double-check valve assemblies (DCVs) and reduced pressure zone assemblies (RPZs).
Backflow preventers in DCV assemblies should be inspected at least once in three years. On the other hand, RPZ assembly models need a little more attention. They must be retested and rebuilt every five years in addition to being tested regularly. Backflow could be quite detrimental if this isn’t addressed.
It’s a good idea to take care of any issues you find during the backflow preventer testing right away. Preventative maintenance like this helps to reduce the likelihood of a severe malfunction.
