A building with 20+ toilets was built in 2004. Florida water is sourced from an aquifer. Bolts pin the toilet tank to the bowl.
Is there any reason not to change:
- all bolts at year 20?
- angle stop valves at year 25?
If replacing the bolts, it probably makes sense to replace the fill valve and flush valve?
What is best practice for 'fleet' maintenance?
UPDATE: I had one bolt fail yesterday and was slowly dripping water, so I replaced the pair. This event prompts the question. Would be nice to do maintenance before the failure, so as to reduce the stress. I am trying to understand if the rest of the fleet will experience similar failures soon.
