Bill, thanks for the info I was definetly considering going with 3/4 hp. the pump will be on the cement floor in corned of nice clean pole barn. if I think it is turning the place into a echo chamber I will build a case around it. I have a bunch of ventilated sofit boards I was thinking of using? where can one get a proper fan that will do the job and last at least a yr?
do i need a fan on it if I dont enclose it??
