  If your Holmatro Water Pump tool isn't operating correctly, consider these potential causes and solutions: * Ensure all couplers are properly connected by disconnecting and reconnecting them. * Verify the pressure relief valve on the pump is in the closed (1) position. * Place the pump horizontally to ensure it is level. * Check the oil level and replenish if necessary, after setting all tools in the output position. * Vent the oil tank if the oil is foaming. * Avoid exceeding the maximum load for the tool. * If the plunger is seized, have it repaired by a Holmatro Certified Technician.

  If the couplers on your Holmatro Water Pump are not connecting or disconnecting, here are a few things to check: * Clean the couplers if they are dirty. * Release any pressure in the tool or hose using the pressure relief tool. This pressure can build up from temperature changes during storage or transport. * Ensure the couplers are aligned properly when connecting; press them together smoothly. * Support and guide the male coupler during disconnection. * Check and clean the snap ring on the female coupler for any blockage. * If the female coupler is faulty, have it replaced by a Holmatro Certified Technician.

  If the flow of your Holmatro Water Pump drops and the lever tends to move back to the tank, it may be due to high vacuum in the tank. Open and close the filler cap to aerate the tank.
