Dealing with sewer backflow
A sewer backflow occurs when then the pressure in the sewer line is altered. It may be decreased inside your home system or a blockage down the municipal sewer line causes sewage to come back to your home. A sewer backflow can cause a flooding of your home especially the basement. The dirty water is also a health hazard and emits a foul smell. Take steps to prevent a backflow before it occurs. A professional plumber can help protect your property from the sewer backup in the following ways.
The major cause of sewer backup is clogged sewer lines. The clogging sometimes happens within your compound. Preventive maintenance helps detect matter that may be building up on your sewer line. The plumber also deals with blockage from tree roots or a sewer line leak that may be contributing to the flooding.
Floor drain plug
Drain plugs are installed just below the floor drain grates to seal off the opening when there is pressure from overloaded sewer lines. Once the pressure goes down, the floating plug is deactivated. This allows water from the house flow into the sewer line.
This solution is inexpensive but may hinder fast drainage in case of a pipe burst or overflow in the dishwasher or the laundry machine. Moreover, the floater should always be free from debris for proper functioning. It may not be ideal for areas prone to flooding such as foundation drainage and kitchen.
This valve is also called backflow prevention valve. It is installed in the basement where your drain exits the house, or at the point where your underground pipe connects to the sewer line. There should be a manhole nearby for maintenance. The solution is a little expensive but highly effective.
A standpipe is an ordinary pipe that is stuck in your floor drain. A watertight rubber seal secures it in place. Any water that rises from the sewer back up goes to the standpipe and not on your floor. The standpipe is placed about three feet above the main sewer line. It takes care of any backup up to this height. You can remove the pipe when there is no flooding threat to allow the drainage of any water spillage.
An overhead sewer is a reconfiguration of the plumbing system such that the opening of the sanitary line is above the sanitary head. The sanitary waste flows into a sanitary pit then an injector pump pumps it into the sewer line above.
The sanitary pit and the pump are installed in the house. This allows for low maintenance and prevents the cases of obstruction in the service line. In case there is a backflow, the wastewater is collected in a space installed below the floor called sump. From this point, it drains into the main sewer line.
Use a licensed plumber when installing the above sewer backflow prevention solutions. Some solutions require authorization from the local authorities. It is vital to take steps to prevent a backflow as it saves you thousands of dollars in sewer line repairs and cleanup.
