To maintain your water features, you should clean them regularly to prevent algae, dirt, or debris from accumulating. Wiping the surfaces with a brush, cloth, or sponge and using a pump, filter, or skimmer to circulate the water can be helpful. Additionally, natural or chemical products can be used to sanitize the water and prevent bacteria or fungi from growing. Refilling your water features periodically to compensate for evaporation, leakage, or splashing is also important. Tap water, distilled water, or rainwater can be used depending on the type and quality of your water features. A water level sensor or indicator can help you monitor the water level and avoid overflow or dryness. Lastly, if your water features break down, malfunction, or leak, you should repair them promptly. You can troubleshoot the problem by checking the power, water, and components of your water features. Alternatively, contacting the manufacturer, supplier, or installer for assistance or warranty may be beneficial.
