Any update? It has been a week and is still very loud.

Update from Friday 4/26:
Unit was turned off at 4:29pm.
Water and Sewer is determining root cause and will address the issue.

Thanks for the update and turning off the blower. It was so nice to not hear the loud noise this weekend. The root cause appears to be loose and missing bolts which hold the metal cover in place. See the original photo and it shows a missing bolt.

You are welcome!

Tom- Thank you for your notification regarding this matter. As you noted ,the fan/blower was shut down Friday evening by a Pump Station Mechanic to eliminate the noise. They are extremely busy attending other stations but will address this problem ASAP. They will diagnose & correct the problem prior to placing it back into service. Thank you for your patience and feel free to contact us through ClickFix regarding any future concern/problem in your neighborhood & community. I passed along your observation of loose & missing bolts for their inspection. Thanks again .
