Wow Pond Pro you would make a great salesmen!

Blue72 if you have the time and want to make your own setup you can do it. I find it funny how folks are worried bout how much noise the pump will put out! Most pumps are down by the pond side and if not there next to the garage or something. I have a gast 0523 rotary pump and it's in a pet crate down by the pond about 80 feet from my cabin and I really have to listen to hear it? To me loud is relative as to what you think is loud I guess?
I agree that loud is a relative term, the big block in my camaro is loud by most peoples standards but compared to top fuel drag car it is quite as a church mouse! LOL
The reason i have particular interest in the noise is the fact I am considering mounting it inside my back pole barn which has my car lift in it and is where all my big projects will be done. I dont want it to make it so I have to yell at somebody working with me in there. If it is to loud for that I can easily run the power to pondside for mounting of everything but having it inside out of the weather seems attractive to my maintenance minded self.
As far as what I have experience with my parents have a gast single piston pump on there 1 1/2 acre pond that I have rebuilt 3 times now in 8 years that is mounted on the back of there cinder block garage. Why it isnt terribly loud I fear it could be if you put inside my 36x56x14 uninsulated pole barn.
