Pump Noise Gets Louder Over Time?
Pump Noise Gets Louder Over Time?
I've had my S1 about 8 months now and have noticed that my rotary pump noise seems to be getting louder - before I hardly noticed it but now it seems fairly loud. Is this normal or to be expected? Any others noticed this or should I just call Chris about it?
Mine seems to be a bit noisier, also. I assume you are not talking about a buzzing or vibrating sound, which can be the result of a loose panel or something sitting on the machine, but rather an actual, slight increase in the noise. The noise I am getting is nothing you would say is abnormal, such as a grinding or squealing or squeaking sound. Just a bit louder.
If you contact Chris, would you please put up a message indicating what was discussed.

The sole difference in the original noisy version of the S1 and the new quiet version is different motor mounts. I could never figure out in looking at the subtle difference in the redesigned mounts how that could possibly make such a huge difference in the noise level, but it sure does.
I think it might be possible for the noise to increase if the bolts on those mounts have loosened up somewhat. For them to work properly the bolts on the top and bottom of the mounts need to be pretty tight.
In any case it's not really a noisy pump. It's actually the electric motor that turns the pump whose vibrations get transferred to the chassis and attached panels if the noise suppressing mounts aren't doing their job.
