Whale FW1215 Watermaster Automatic Pressure Pump - 12L - 45PSI - 12V

The Whale FW1215 Watermaster Automatic Pressure Pump delivers consistent, on-demand fresh water throughout your vessel with zero fuss. Built for anglers and cruisers who demand reliability on extended trips, this 12-volt automatic pump maintains steady pressure to galley, head, and deck wash systems without manual intervention. Over a decade of Whale Marine engineering ensures this compact unit handles the salt-spray, vibration, and temperature swings that come with serious time on the water.

The FW1215 operates at 45 PSI maximum, ideal for typical marine freshwater distribution where you need adequate flow without hammering seals or fixtures. Its 12-liter capacity balances compact installation space with practical reserve volume, minimizing pump cycle frequency and extending motor life. The automatic pressure-switch design activates only when demand drops pressure below threshold, cutting parasitic battery drain—a critical advantage when living aboard or anchored away from shore power for days at a time.

This pump suits any cruising sailboat, center console, or trawler running 12V DC systems. Dimensions of 8 x 6 x 10 inches fit neatly in engine rooms, bilge areas, or lazarette corners where real estate is precious. Weighing just 4.4 pounds, installation requires minimal structural reinforcement. Whether you're making coffee at anchor in the Bahamas or washing down the deck after a dawn charter, the Watermaster delivers the silent, steady pressure that separates a comfortable vessel from a marginal one.
