The guys at whirly bros are great to deal with. Very informative and honest. They went out of their way to send me pics of better pumps and explained what I would have to do to upgrade. I chose the plug and play option and it was exactly what I needed.
We try our best.

I received the pump in good time. Had a little trouble getting it to work. The owner talked me through it and it work perfectly after I got it installed. Only question I have is that it has a faint smell when in operation. I'm thinking cuc it's new. If still persists after time I might give me. Whirly a call back. He has been great to deal with. Very friendly and knowledgeable. Thanks very much. Kevin Wiest
Thanks Kevin, its new so that smell can be expected. We trust that this pump will work for many many years to come.
