Have you ever imagined raw sewage spewing out of your sink, shower stalls or toilets? With many parts of the country recording high precipitation, such unfortunate occurrences have been experienced by a number of families. These kinds of backflow have their own setbacks. They lead to a damage that will prove a challenge to repair and also lead to massive health hazards.
The sanitary system of most homes is eventually connected to the sewer system that the town municipal manages.
Quite a number of old homes are established at sites where these sewer systems are established.
The reason as to why several backflows happen is because some homes have combined the sanitary systems and the storm water systems. Therefore, after the water has been collected in the gutters, it is usually discharged in the sanitary system.
The other factor that may cause the increase of water level could be illegal connections.
When heavy rains fall, the sanitary main may get filled to such levels that it is no longer able to hold. This makes it to eventually drain off because the increased volume will no longer be handled.
Water will always want follow a path that has least resistance. It will tend to flow back, going even through the narrowest opening. Such openings can be found in the floor drain or any other lowest located plumbing drain in the building.
And that is what has always brought people to ask themselves an important question: how can I be able to prevent sewer backflow?
As much as you are remaining realistic to yourself, you need not to worry so much. Two devices are in existence that you use to reduce the excess water in the basements and pipes. These are the backwater valve system and the overhead sewers.
An option that you can use in implementing backflow prevention is to use backwater valve system on the sewer line. This kind of valve has a horizontal check valve that is designed in such a way that waste will flow in only one side. A metal disc is in such a manner that it will open as waste flows forward and then closes as it tries to come backwards.
An option is to install a basin in front of the check valve at the waste collection place. There is then a pump that forces the waste past the valve in to the sewer line.
Annual maintenance is a necessity so as to lubricate the hinge disk. Debris in the sewer line will cause failures.
The overhead style is a better option that you can take as an alternative. As per your existing layout, the lower sanitary level can be separated into a sanitary pit. The waste discharge is then pumped into the sanitary system.
Since the pump and the sanitary pit are installed indoors, the maintenance that is needed is less. The chances of the service line getting stuck are minimal since there is no installation on it.
