Suspension pump, how often does it run?

[The-Acre]

I just thought I'd ask this question although everything works fine.  I hear the suspension pump run for a few seconds most mornings when I start up, I'm assuming this is normal for it to briefly run each day?  It only runs for about 10 seconds.

Sounds about right, just making up for pressure lost overnight, no system is completely airtight sealed.

I agree. Same for me ...
