Below are photo instructions for checking where the source of a rattling pump is coming from. Before doing this we recommend verifying that the pump is receiving appropriate water flow(~1.5 GPM).

First, we want to check and see if the rattle is happening from the front panels or pressure gauge rattling on each other when the machine is operating.

If that is not the case we will want to check the position of the pump and if it causing an internal rattle.
