Had a similar issue at a client's house last year—pipes knocking and clanking every time the hot water came on. Turns out their plumbing was expanding and contracting against wooden joists, creating that "talking" effect. Secured the pipes with plastic clips and added some felt padding where they touched wood. Quieted things down pretty quick. Funny how houses always find new ways to keep us on our toes...
Had a similar thing happen at my aunt's place—pipes were knocking like someone owed them money every time she ran a bath. We thought the house was haunted at first, no joke. Turned out it was just loose pipes rattling against the studs. A few foam sleeves and some clips later, the ghosts packed up and left town. Houses really do have a sense of humor sometimes...
"pipes were knocking like someone owed them money every time she ran a bath"
Haha, that's exactly how mine sounded before I fixed them. People underestimate how common this issue is—it's usually water hammer or thermal expansion causing the pipes to move around. Foam sleeves and clips are great, but I'd also recommend checking your water pressure. If it's too high, installing a pressure regulator can make a huge difference. Mine went from angry banging to quiet whispers overnight... houses definitely keep us on our toes.
Had a similar issue at an apartment I used to rent—pipes sounded like they were arguing back and forth anytime someone showered upstairs. Turned out the landlord had cranked the water pressure way too high trying to fix another issue. Once we dialed it back, the banging stopped completely. Foam sleeves are helpful, but honestly, checking water pressure first can save you a lot of hassle... and headaches.
Dialing back water pressure can definitely help, but I'd still be cautious about jumping straight to that solution. Sometimes, noisy pipes can signal loose fittings or brackets that could eventually lead to leaks or even bursts if ignored. Had a friend who thought adjusting pressure solved everything—until a pipe burst behind their drywall months later. I'd always recommend checking for loose joints or supports first... better safe than sorry. Foam sleeves are decent, but they're more of a band-aid than a fix, imo.
