What is Backflow?

Backflow happens when water starts to flow in or out of your house in the opposite direction of how it normally should. When water direction gets reversed unintentionally, your water supply may be contaminated with solids, gases, or liquids. It can also happen when clean and dirty water mix together.

The water coming from the municipal local water supply into your home is pumped into your house at a certain pressure level. This level of pressure makes water flow through your faucets and can be reduced in certain circumstances. This happens when a water main breaks or pipes freeze. When your water pressure is reduced, it can be contaminated by other sources entering your water supply.

How Backflow Testing Works

Backflow preventer valves help stop backflow, but like anything else, they can fail. Backflow inspection by experienced plumbers in Eastpointe, Michigan, ensures that your backflow preventer valve is working properly. Devices like this have built-in ports that allow them to be easily tested.

First, all downstream water is turned off, which must be done before the device can be tested. A gauge can be used to check the backflow valve for high or low pressure. Contact us to schedule your backflow testing today.

Why Backflow Testing is Needed

Backflow testing should be an important part of a home maintenance routine since it ensures the safety of your drinking water. While backflow prevention devices help, they can break. A loose valve can be a direct cause of backflow.

When there is backflow in your water supply, not only can it contaminate your home’s drinking water, but it can also flow into the community, posing a public health risk. This is why it is important to conduct frequent testing.

We noticed sewer backing up in our basement last night; called this morning and had someone out in less than 3 hours. Kenny was on time, super polite, and answered all my questions with a thorough explanation. He was able to clear the blockage on the line and look over a few other concerns I had in the bathrooms. I highly recommend this company and will definitely use again for any future plumbing needs. Hopefully I won't need them any time soon. Read More

Brian did a fantastic job with my sump pump. It failed during the night and he was there the next morning. He was patient and explained everything to me thoroughly. He went above and beyond by fixing the dripping noise where the water comes into the sump. Thanks Brian! I listened to that drip for six years lol. We also use Waterworks for all our investment properties and have been happy. Read More
