How To Install A Backwater Valve

On March 20, 2018 by Preeti Shah

Sewage backflow is a big problem in large plumbing networks, especially during heavy rainfall. Overwhelmed municipal sewage systems push contaminated water back into safe home systems, causing floods. Backwater valve installation helps prevent this problem. It is a one-way fixture that doesn’t allow water from public systems to enter your property. Most newly constructed homes already have a valve but older properties don’t. 

  1. Backwater Valve Access Box

Plumbers first fix an access box at the installation site. This cover keeps soil or debris away from the backwater valve and allows easy access to the fixture. Without an access box, plumbers will have to excavate the area every time they need to carry out repairs or maintenance. Once plumbers install the box, they move on to installing a new backwater prevention system.

Backwater valves need to be installed in the right location for them to function properly. This fixture fails more often if there’s a flat or negative slope on the property. Experienced plumbers examine sewage lines carefully to determine where they can install this valve and ensure it works well.

A backflow valve can develop problems even if it is installed properly. Frequent use can cause wear and compromise its structural integrity. This fixture is automatic so most homeowners don’t realize how often their plumbing system triggers the valve. Regular inspections help identify this wear and tear early. Plumbers replace worn down valves to ensure there are no fails during the storm season.

You can prolong a valve’s lifespan by carrying out regular maintenance. Plumbers will clean the fixture, check its structural integrity, and perform the needed repairs. Your valves will be more likely to fail without this essential maintenance. 

  1. Cast Iron Backwater Valve

You can choose between a PVC or cast iron fixture during backwater valve installation. PVC is inexpensive and a good option for people on a budget. It will deliver good performance but has a higher risk of failure. Cast iron can withstand more pressure and is more reliable. If your region experiences frequent storms and floods, cast iron is a better solution. While this fixture is a little more expensive, it is also durable. With proper maintenance, it lasts for decades.
