jackoup Posted April 22 Report Share Posted April 22 Hello, I have a Coleman Saluspa. Pump is always on to keep the water warm. But the pump is making a humming noise, particularly strong if you are far away (50ft) due to the low frequency noise. The spa is on a concrete, in a corner consisting of a wall and a wood fence. The pump is on a thick rubber mat to absorb vibrations. But the pump still makes a loud humming noise that propagates to the neighbor's houses. Any suggestion to isolate the noise? Could I build some kind of a box using plywood + foam and put the pump inside it? Quote Link to comment Share on other sites More sharing options...
