Seems like my older toilet is starting to get clogged a lot more easily than it used to. I'm able to keep it running but get tired of snaking the drain every three days. Part of the problem is 4 YO using too much TP but I think the bigger issue is build up over the years. Pretty sure this one was put in with the house 16 years. I snaked it 4-5 times yesterday and was getting rust deposits and other buildup coming back but it didn't make much difference. Is there something I can do to get it running like new?
