In some flood
prone areas, flooding can cause sewage from sanitary sewer lines to back up
through drainpipes into buildings. These backups not only cause damage that is
difficult to repair but also create health hazards. A good way to protect
buildings from sewage backups is to install backflow valves, which are designed
to block drainpipes temporarily and prevent return flow. Backflow valves are
available in a variety of designs that range from the simple to the complex.
Keep these
tips in mind if you have backflow valves installed:
▪ Changes to the plumbing in your property
must be done by a licensed plumber or contractor, who will ensure that the work
is done correctly and according to all applicable codes. They can advise
you on the relative advantages and disadvantages of the various types of
backflow valves.
▪ Valves should be installed on main waste
drainpipes that leave the structure or that are connected to equipment that is
below the potential flood level. Therefore, valves may be needed on washing
machine drain lines, laundry sinks, fuel oil lines, rain downspouts, and sump
pumps, as well as sewer/septic connections.
▪ If you have a sump pump, it may be
connected to underground drain lines, which may be difficult to seal off.
We
are in the middle of hurricane season and flood season is rapidly approaching.
