Backflow prevention devices

Let us know how you want to install your backflow prevention device. You can also use this form to tell us if you already have a device installed, or to send us questions or comments about backflow prevention. 

You need to complete this form for each property you own that needs a backflow prevention device.


There may be potential restrictions with space or location. This could impact us being able to complete the installation for you. In this instance, we will contact you to discuss further options.

This device prevents water from your property’s water pipes back-flowing into the public pipes.
