Questions & Answers

Is this a genuine original part?

Yes, this is a genuine SEAFLO manufactured product, known for high reliability in marine and RV plumbing applications.

How do I know if it is compatible?

We recommend checking the SKU/MPN and Cross Reference list provided above. If your system requires a 12V 4.0GPM boost, this is an ideal replacement or upgrade.

What are the benefits of the 8L accumulator tank?

The 8-liter tank acts as a pressure buffer. It allows for small amounts of water use (like washing hands) without the pump having to start up, resulting in a quieter environment and significantly longer pump life.
