Install a Sump Pump & Valves
A check valve and a shut-off valve can be installed to provide
a good measure of protection from basement flooding. These valves can
isolate the house plumbing from the public sewer in the street. The check
valve includes a flapper that shuts when water level in the public sewer is
high enough to flow back into the house. The shut-off valve can be manually
closed as an added measure of protection. The shut-off valve will also need
to be closed if debris becomes lodged in the check valve preventing its
full closure.
The homeowner will need to discontinue or, at least, sharply curtail the
use of the sanitary facilities while the potential for flooding exists.
During this time, showers, the clothes washer, and dishwasher cannot be
used.
Both the sump pump and the valves can be installed for a total cost of
about $2800 or more. Each home is different.
