Important:
1. Total output (HP x service factor) of replacement motor
must equal or exceed motor being replaced.
2. The pool motors on this page are
NOT equipped with a
Safety Vacuum Release System (SVRS)
. SVRS helps
prevent drowning due to body entrapment on underwater
drains. In some pool configurations, if a person’s body
covers the drain, the person can be trapped by suction.
The SVRS turns off the pump if this occurs.
Depending on your pool configuration,
a SVRS may be required to meet local, state, and federal
requirements.
