KOHLER K 78172 G Stopper Assembly Brushed Review

I have had 3 of these rings and have been in constant use for 10 years; they work very well. EXCEPT the o-rings get weak and start to leak a little after about 5 years. The replacement ring size is called "Dash 122" (also "#122"); A website called oringsandmore sells a 25-pack for only $2.15 plus taxes etc. Or you can track Oring with sizing information at your local hardware store or major home center retail store.
