I just finished fixing a leaky toilet. My cost was about $42 for the part. But, I got to thinking what would it have cost me had I taken it to the dealer.
Here is the part that needed to be Installed.
Here is where the resides, behind the toilet bowl.
1) $125 Fuel for 6 hr round trip to the dealer
2) $50-$75 for the part with dealer mark up
3) $100 Labor if I am lucky
4) 1 day out of my life if the dealer actually gets it done in a day.
Note - I had to take the bowel off do to the fact that there is not enough room to remove the part because of the proximity to the wall.
