The Vetus WP1220B is intended for installations where a higher water output is needed, such as onboard water systems with multiple outlets or applications where water must be available quickly. Its self-priming construction and automatic pressure switching allow the pump to operate on demand as soon as water is drawn. This version also includes a built-in check valve and thermal protection, making it well suited to regular use in a pressurised water system.
