That says leak!

Dye Test your toilets!

This could be the fluid master in the tank
If you don't see water running around the inside bowl your flapper is ok

Actually the Korky fill valves are far more likely to pulse the flow like that than a Fluidmaster when the flapper is leaking....

No sorry 2 different ideas one chance fluid master two if the water isn't trickling inside the bowl then flapper is fine

If it isn't plumbing then let's talk about duct work and metal chimneys!

I saw this earlier this morning on All Experts and from the Video, I thought I was looking at a Hydronic heating system. They are famous for making noises. Not like the one in the video exactly, but that is what it looked like to me.

Redwood, isn't that what I'm seeing. Valves with tags on them probably describing what part of the house they service etc.

Only one appeared in the thread and I got dizzy with the spinning camera....

looking at it again I found the playlist link and got dizzy again but yea it looks like a heating system...

Nope, I have a normal gas heating system, not a hydronic one. The pipes are just cold water lines coming off the main and heading to the outside spigots. The tags were put on by the house inspector just marking what each valve does (front, back, water heater etc). I'll turn off the toilet (s) this weekend - I wanted to do it when I was home for a decent amount of time.
