Caution! Hazard of Flooding
If toilet uses raw water for flushing at ANY time, a raw water pump controlled by an automatically operat-
ing demand switch MUST NOT be installed . If the onboard water valve or any plumbing connections
were to leak, the automatically operated pump would start and could flood the boat . Failure to comply
with this warning can cause loss of property and life .
