To make our product last longer, we also recommend that you regularly clean the pump and change the filter. Questions: Q1: What should I do if my cats don't like it? Most cats like flowing water. It may take them some time to get used to this new way of drinking water. We recommend removing their original water source to help them get used to the new way of drinking better. Let us know if your cats are still having trouble with this. Q2: Why does the water dispenser not work? (1) We advise you to check the power supply first if there is a problem. (2) Check the pump whether it works normally. Pumps are mechanical devices that deteriorate over time due to repeated use. We advise you to inspect and clean the pump regularly to ensure that it is not blocked by dust or hair. (3) If you have any problems with the pump, we can provide a replacement pump under warranty. Q3: Why does the machine make noise? (1) Make sure the water level is higher than the MIN line. The fountain will keep running and making noises to remind you to add water when it is below the MIN level. (2) Please check the pump to see if any foreign matter has accumulated in it. If this is the case, clean them using our small brush and following the instructions for use. (3) The product will wear out or damage the impeller due to the continuous high-speed operation of the pump, which may generate noise from the water dispenser. If your pump has been running for a while, you may consider buying a new one. (4) If you have any problems with the pump, we can provide a replacement pump under warranty.
