Questions & Answers
Is this a genuine original part?
This is a premium quality SEAFLO manufactured part, engineered to provide high-performance water pressure for marine and RV environments.
How do I know if it is compatible?
We recommend checking your system voltage (24V) and plumbing size (1/2" NPT). This pump uses an industry-standard mounting pattern, making it a drop-in replacement for most major brands.
What are the benefits of the Internal Bypass?
The bypass allows water to circulate within the pump head when fixtures are only partially open. This prevents the pump from "rapid cycling," resulting in a quieter user experience and significantly longer motor life.
Note: 4boats.co.uk - Please verify your system voltage is 24V before purchasing. Ensure use of a pre-filter to protect valves from debris.
