Hello everyone, I am hearing a swishing sound from our ground loop Bosch circulating pump. The 3 ton unit seems to be working fine but I am concerned about the swishing sound. We have another 3 ton unit and there is no swishing sound from that circulating pump. Does the line need to be purged, if so, how difficult and costly is that? I welcome your thoughts and advise. Thank you, Ed
Hi and welcome! Do a simple pressure check on the loop. If it low try gooseing the pressure to eliminate swooshing noise. Eric
Thank you! After reading other entries and other stuff on the net I was thinking that it might needed to be purged. I will have someone come in and check it out.
