Random toilet flushing
Hey--I live in an almost 100 year old house outside Boston,MA. We bought this house 7 years ago and updated bathrooms,kitchen,wiring,appliances. Lately,the upstairs toilet will,seemingly randomly, not exactly flush,but fill the tank,just a small amount. More so at night,but we may be more aware of it at that too. Plumber came and heard this happen,replaced the flapper. Problem is still going on. I'm wondering,where is this water going?? Is my water bill going to be thousands of dollars?? No obvious signs of leaking around toilet or pipes in basement. Any ideas? Thanks.
