Check valves are recommended for use in the
tubing string for ESP system to keep the discharge-tubing full of
fluid when the pump is off. The check valve allows for a full
column of fluid/head for the pump to restart against, thereby;
eliminating the possibility of damage to the pumping system that
may be attributed to insufficient head. It will also eliminate
fluid from flushing back through the pump enabling a quicker
restart. The check valve is run generally two or three joints above
the pump. If the check valve is not installed, the pump should not
be started until the fluid column has had a chance to equalize,
eliminating the chance for a twisted shaft in the pump, or a burned
cable or motor. (A minimum of thirty minutes is recommended.) When
a check valve is used, it is recommendedtt to install a drain
valve.
