For anyone that has these pumps, can you give me an idea of what sound they make. I've heard so many different reports and dont know whats true and whats not. I have a situation where I want to add the absolute minimal sound to the system. In my opinion, the Tunzes I use are virtually silent. I'd take them out of my system and replace them with Vortechs possibly if I knew they were the same.
Ryan - I followed your thread a little while back and you said there was a bit of noise. Is this still the case? has it calmed down (as opposed to you just getting used to it)?
Chad - I know you've had yours for a little while now. How are they for you?
