If the pump is making more noise than usual, it is likely that one or more bearing is worn. The pumps bearings allow the drive shaft to pass through the pump housing and attach to the impeller. A squeaking or clicking sound coming from the bearings is a warning sign that they are wearing and in danger of breaking. Worn or noisy bearings should be replaced immediately to prevent further damage to any related components. All bearings will wear over time with regular use and will require replacing eventually. The pump housing will need to be disassembled to access the bearings. Refer to your owner manual for the proper replacement part numbers should new bearings be required.


If a proper filter is not used on the intake side of the pump, debris can be allowed to enter the pump housing. This debris (usually dirt or sand, sticks, leaves, rocks) will cause damage to the impeller and can cause the pump to make more noise than usual when pumping water. If debris enters the pump, discontinue use immediately and flush out the system. In certain cases, the pump may have to be disassembled in order to remove all of the debris inside of the housing. It is important to always use an adequate filter on the pump, and to check it regularly to keep it clear from clogs or blockages.
