My pump is very loud.
Try keeping batteries in the pump. Placing batteries in the pump's main unit fills the empty space and muffles the pump's noise, which can inadvertently act as an amplifier of sound when empty.
Test your pump's noise level by running it on different surfaces available in your home or office; sound reverberates more strongly through objects that have a lower density than others.
If your pump's noise level suddenly increases, there may be a foreign object that was sucked into the pump which has caused a blockage. This is usually associated with a sudden loss of suction problem.
