18 years those toilets lasted, and crapped out within 2 months of each other. Fascinating. Now to replace appliances. The refrigerator and dishwasher are still working great. The stove, on the other hand, is down to 2 functioning small burners. The oven crashed 2 years ago. 🤷‍♀️ Just replace all 3 at once, you say? But that kinda ruins the experiment, I say.
