Yeah, foam pads can be hit or miss depending on how your pipes are set up. Plastic hangers are a solid choice—I've seen them used a lot in older homes where the pipes run super close to joists or studs. Had a similar situation at my uncle's place last year; we tried foam first too, but the knocking kept coming back after a couple weeks. Ended up using rubber-lined clamps instead of plastic hangers, and that did the trick for us. Every setup's a bit different though, so it's cool you found something that worked well for yours. Plumbing noises can be tricky...sometimes you gotta experiment a bit before finding the sweet spot. Glad you got it sorted out!

Exactly this. I've seen setups where plastic hangers worked wonders, and others where rubber clamps were the only real fix. Good call on trying different options—plumbing's rarely one-size-fits-all. Glad you nailed it down.

This is spot-on advice. Plumbing noises can definitely be a pain to troubleshoot, and there's rarely a universal solution. A few extra things I've found helpful over the years:
- **Check your water pressure:** High water pressure can cause pipes to vibrate or bang around more than usual. Installing a pressure regulator or adjusting your existing one can sometimes quiet things down significantly.
- **Air chambers or arrestors:** If you're getting that loud banging sound when shutting off faucets (water hammer), installing air chambers or water hammer arrestors at key points can help absorb sudden pressure changes.
- **Pipe insulation:** Wrapping pipes with foam insulation not only helps dampen noise but also protects against temperature fluctuations. It's an inexpensive fix that's often overlooked.
- **Securing pipes properly:** Sometimes the issue isn't just what type of clamp or hanger you use, but how frequently they're placed. Pipes should be secured every few feet—especially around bends or joints—to prevent movement and vibration.
I remember one job where the homeowner swore their pipes were "haunted" because of weird squealing noises every night around the same time. Turned out it was just thermal expansion causing slight shifts in the piping when their heating kicked in. A bit of insulation and adjusting a few hangers sorted it right out... no ghostbusters needed.
Anyway, plumbing's always got its quirks. Glad you found something that worked for you.
Had a similar issue at my place a while back. Pipes kept knocking whenever we turned off the shower—drove me nuts. Tried clamps and insulation first, but turns out our water pressure was way too high. Installed a pressure regulator, and problem solved. Sometimes it's just trial and error until you figure out exactly what's causing it... plumbing can be weird like that.
Had a similar knocking issue, but pressure wasn't the culprit in my case. A plumber friend recommended checking the water heater instead—turned out sediment buildup was causing weird pressure fluctuations. A quick flush of the tank helped a lot.
Just a heads-up:
- Pressure regulators can be pricey and might not always solve the issue if it's sediment or air pockets.
- Before investing in one, maybe try flushing your water heater or bleeding air from your lines first.
- Also, high water pressure isn't always bad—just needs to be within safe limits. Too low, and appliances might not run efficiently.
I get being cautious though... plumbing issues can escalate fast and get expensive. Always good to rule out simpler fixes first before dropping cash on bigger solutions.
