I am home now. As soon as the laptop charges some, I will have video and sound via iSight. I will try to include the dB meter in the vid so you can "see" how loud it is.
PS: Phil those sound clips were made before i realized that there was a big leak were the pipes met. I got a clamp to seal it from NAPA, and it got a bit quiter. Most of the dronning went away after putting the clamp on. The clamp fixed the leak but it is still f'ing loud.
Yes it is catless.
If you have upgraded your stereo, I think that you have, you might drown it out.
