Do all modern toilet tanks have overflow tubes? I ask because I went on vacation just a couple of days after my toilet started to drip in the tank. I'll be gone for a while so drips can quickly get out of hand before you know it.
If it has an overflow tube I should be OK until I get get to it. BTW, this toilet is 12 years old now. How do you stop a drip on the handle part? Will I need to call a plumber?
It's a very slow, irregular drip, maybe once every 5 seconds or more. TIA
