The Whale Watermaster FW1225 is a 24V automatic pressure pump rated at 3 GPM and 45 psi. It self-primes up to 3 m (10 ft), works on fresh or salt water, and includes a strainer to protect the pump from debris. The unit is IP65 rated and can run dry without damage. It connects to 15mm quick connect plumbing or 1/2" threaded hose fittings.
Our take
The Watermaster is rated to run dry without damage, so an empty tank will not harm the pump. It is a 24V unit that gives 3 GPM at up to 45 psi and self-primes to 3 m, so confirm your boat runs 24V before fitting it.
From our buying guide
Size a freshwater pump by the outlets that must run at once. Jabsco's rule of thumb is 1 GPM per outlet, and the listed flow is open flow, which falls as pressure rises.
Check before you buy:
- The data sheet shows flow at pressure. One Shurflo gives 4.0 GPM at 0 psi and 2.0 GPM at 40 psi.
- You have an inlet strainer, which Jabsco says is required in every freshwater pump installation.
- An accumulator suits the pump. Jabsco says one cuts cycling on a pressure-switch system, and not to use its accumulators with variable-speed pumps.
