The Impulse® is the most advanced battery-operated, computer-controlled sensor flush valve you can find-from Delany engineers who patented the very first battery-powered flush valve. Here is the solution to bathroom conversion without complicated, expensive renovations. The Impulse® is completely self-contained and takes no longer to install than a manually operated flush valve. There are no electrical hook-ups required. Designed for easy, single-component installation, the Impulse® operates reliably for years on one lithium battery. Coyne & Delany.
