Some months ago, I noticed our toilet handle on our 30 year old bathroom
toilet was loose. It could have been the original handle on this toilet,
I don't know, but upon opening the top tank lid, I saw the handle nut
had become loose. I tightened it and within a week upon inspecting, I
saw it had become loose again. So, I just took the handle, chain, etc.
out and replaced with a new one. It seemed to be working fine, but this
morning, upon inspecting it, I saw this handle's nut loose again. Now, I
should mention that I hand tightened the nut upon installation and gave
it an extra little bit of 'force" if you will with my hand, nothing
major but I didn't use a wrench with the nut for fear I might damage the
porcelain by tightening too much. My question is, since it's worked
itself loose again after a few months, is it recommended that I tighten
it with a wrench this time (and if so, how much?), or has the porcelain
behind the nut worn away to where it's not making a good tight hold?
Thanks in advance for any assistance.
