Making sure your home’s pipes are up to code - how I do it

I wish there was a more eco-friendly fix than dumping all that water every time.

Yeah, that’s the part that bugs me too. Draining air chambers feels like a waste, but if you skip it, those pipes will remind you at 3am… Trust me, I’ve tried every “silent” hanger and cushion out there - old copper still finds a way to rattle. At least keeping things up to code means fewer surprises when you open up the walls (which is never as fun as HGTV makes it look).

Honestly, I hear you on the water waste. But in my experience:

- Air chambers lose their cushion over time, so draining’s kind of necessary if you want to avoid that midnight hammering.
- Tried those water hammer arrestors? They’re not perfect, but they last longer and don’t need draining.
- Sometimes it’s just old pipes doing what old pipes do… insulation helps a bit, but never totally solves it.

Curious - has anyone actually had luck with those newer plastic pipe systems for noise? Copper’s classic, but man, it can be stubborn.

I swapped out a section of my old copper with PEX last year when I was redoing the laundry room. Honestly, I was surprised by how much quieter things got. No more crazy banging when the washing machine shuts off the water fast - it’s more of a dull thunk now, if anything. The flexibility seems to soak up some of that shock, I guess? Not saying it’s totally silent, but it’s way less dramatic than before.

But yeah, I hear you on the water hammer arrestors. I put one in under my kitchen sink and it worked for a while, then started making this weird squeal instead. Go figure. Sometimes I think these fixes just move the noise around.

Insulation helped a bit with hot water pipes rattling against the joists, but didn’t do much for actual hammering. Still debating if it’s worth re-piping more of the house with plastic or just living with the occasional clunk...

Sometimes I think these fixes just move the noise around.

That’s honestly been my experience too - like you solve one rattle and suddenly there’s a new mystery squeak. Did you notice any issues with water pressure after switching to PEX? I’ve heard some folks say it can drop a bit, depending on fittings and layout.

- Yeah, I’ve noticed that too - fix one thing, another pops up somewhere else.
- Swapped to PEX last year. Water pressure stayed about the same for me, but I was careful to use full-flow fittings and minimize sharp bends.
- Some folks go overboard with elbows and tees, which can definitely cut down pressure. Worth mapping out your runs before you start.
- One thing I didn’t expect: PEX seems quieter overall, but if it’s not clipped down tight, it’ll slap against studs when the water shuts off. Learned that the hard way...
