Hi All,
About a week ago, I noticed that shower drain wasn't draining as fast as it usually did - cleaned it - though there wasn't anything that appeared to block it.
Ran shower again, and noticed same thing... also noticed that at the very end, there appears to be a back flow of water surging up from the drain and then back into it again. I've tried drain unclogging liquid (suspecting it may have been something) but the problem seems to be still there.
Any ideas on what may be causing it or how to fix it?
Thanks!
John
