Frequently Asked Questions

Q: What does the anti-airlock feature do?
A: The anti-airlock feature allows the pump to self-clear trapped air from the inlet line. This is particularly useful when the boat is anchored or running in choppy water where air can enter the pump and stall flow.

Q: Can I use this pump for a washdown connection?
A: Yes. The 357-103-10 includes a dual-port fitting that allows simultaneous livewell circulation and a washdown hose connection without additional fittings.

Q: How do I clean the pump?
A: The Piranha series pump includes a removable cartridge that can be pulled and cleaned without tools. Regular cleaning of the cartridge helps maintain flow rate and extends pump life.

Q: Is this pump ignition protected?
A: Yes. The 357-103-10 is ISO 8846 compliant, meaning it is ignition protected for installation in marine fuel-vapor environments. It is also CE listed.

Q: Will this pump run dry without damage?
A: No. Like most centrifugal livewell pumps, this pump should not be run dry. Ensure the inlet is submerged before operating and use a float switch or timer if needed to prevent dry-run conditions.
