LESLIE: Heading over to chat with Merrill in Rhode Island. What can we do for you today?
MERRILL: I have a problem with my toilet . This sounds strange. Once in a while it just flushes itself. (chuckles)
LESLIE: That’s not strange.
TOM: You have ghosts in your house, Merrill.
MERRILL: That’s what I was thinking.
MERRILL: I mean it happened in the middle of the night.
TOM: It’s a very simple explanation. What you have is a leaking flush valve.
TOM: That’s the flapper valve in the bottom of the toilet tank and as the water leaks out, when it gets to a certain level, the fill valve kicks on again and then refills the toilet; it sounds just like a flush.
MERRILL: Oh, really? That sounds good. I’ll try that. Thank you so much for helping me out.
TOM: (overlapping voices) You’re welcome.
