I get a pretty loud thumping noise after I run the hot water, eg, after cle
aning dishes. The thump occurs maybe once every 10 minutes. I've done a lit
tle Google-research, and I understand that the copper pipes are expanding,
then contracting, and somewhere along the line they bang against a stud. Th
at makes sense. That's sort of the sound I get. But I still have a few ques
1. The thump continues hours after I've stopped running the water. Eg, I r
an the sink at 5:00 and I still get a thump at 8:30. Not as frequent, but s
till there. Is this reasonable?
2. I don't know how long I've had this problem, but I don't think it was h
appening when I first bought the house some 20 years ago. Is there any chan
ce it will just go away in a year or two?
3. My research convinced me that it can not be fixed, I should just live w
ith it. Is that the opinion around here?
The last house I lived in for 25 years had a similar problem. When the
hot water in the master bedroom sink was run, we got a squeaking
sound. Time between squeaks would vary, up and down. Figured it was a
copper pipe that was rubbing against a stud, probably as the house,
built in 1971, shifted a little. We just "lived with it". Got to where
we just "tuned it out", not noticing it every time.
When I leave my house, and almost slam the door, about 4 seconds
later, I hear a noise. Not every time, but maybe 100 times already.
Never right away like one would expect. I always forget to turn
around until it makes the noise. Maybe if I turned around in time I
could tell where it was coming from.
It seems like a weight is hanging from a string, and when I slam the
door, like one pool ball being hit by another, the weight and string
pivot away from hanging straight down, they go out a ways, and then
fall back and that's when it makes the noise. But I have nothing that
could do that.

ive with it. Is that the opinion around here?
Could be an air pressure thing.
I have a storm door and entry door from my house into the attached
garage. I also have a cat (and sometimes raccoon) door in the garage
door itself. Sometimes - but not always - when I open the storm door
the cat (and sometimes raccoon) door will swing with the change of
pressure and go "thwack thwack" as it engages the magnet that keeps
it in the closed position. Perhaps something in your house is swinging
due to a change in pressure caused by the closing door and may not hit
whatever it is hitting until the "swing conditions" are just right.
You say four seconds? Maybe it's starting to swing when you *open*
the door and the closing of the door has nothing to do with it or
maybe it takes both actions to cause the noise. Have you tried one
without the other?

It's just that if it's inside, it would have to be pretty loud for me
to hear it from outside the house.
No storm door, no cat, no raccoon, no garage, no cat door.
I do have a mail slot in the door, but that makes a higher pitched
sound, and couldn't possibly take 2 whole seconds to go up and back
again. Actually it hs doors on both sides. The door opens in, so
slamming it shut would make the outer door leave its location a little
** (The mail-slot door on the inside would just be pressed harder
against the door and wouldn't move.)
Let me change that to 2 seconds.
I've opened the door without closing it 100's of times. It's rare I
close it without having just opened it, except when I'm going back
into the house. I've never heard this noise when I go into the house.
It seems like the downspout, something as heavy as that, is moving
away from the house and then swinging back, but the downspout isn't
loose at all. Or something in the closet just inside the door. I'll
look again to see if there is anything loose in the closet, but I
think I would have noticed that already.
