While taking a shower this morning, I suddenly heard a loud noise that I couldn't identify. It lasted a few seconds. I continued my shower without incident but a few minutes later, after drying off, noticed an increasingly foul odor. I turned the fan on in the bathroom and left if for about a half hour or so. The smell dissipated and when my daughter took a long shower later, all was well. No noises; no smell. That was about 5 hours ago. Do I need to do anything at this point?
Thanks for any help!
