Installing a flapper valve on the end of the evacuation line
● Install the flapper valve in the bottom
of the manure storage pit.
● The flapper valve prevents manure
flow back as long as manure
remains consistent enough to seal
the flapper.
● The flapper valve may leak if manure
becomes watery, or if a piece of
material gets stuck between the
flapper and the valve housing.
Manure storage pit
● In a sand bedding operation, if the
risk of freezing is low, the flapper
valve can be installed higher than
the bottom of the pit in order to
prevent sand from accumulating on
top of the flapper.
● The flapper valve should be preceded by a manual safety guillotine to
ensure that the evacuation line can be shut off in case of emergency.
