  If your Stenner Water Pump head rotates but there's no output, consider these potential causes and solutions: * Replenish the solution if the solution tank is depleted. * Adjust the suction line to be 2–3" off the bottom of the tank to avoid sediment. * Inspect or replace the suction line if there's a leak. * Replace the compression ferrules if they are installed incorrectly or damaged. * Inspect and clean the injection point if it's clogged. * Clean and/or replace any clogged suction/discharge tubing or the injection check valve. * Replace the pump tube if its life is exhausted.
