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

I had one under my laundry sink and it went off because I spilled a bit of detergent, not water...

Swapping to PEX was a smart move. I did the same after a pinhole leak in my old copper line—never looked back. Those water alarms are more trouble than they’re worth sometimes. Like you said, just checking things yourself is usually simpler and cheaper.

I hear you on the false alarms—those things can be a pain, especially in spots like the laundry room where spills are just part of life. But I’ve gotta say, after seeing a basement flood from a slow leak that went unnoticed for weeks, I’m still a fan of water alarms in the right places. Had a client with a finished basement and by the time they noticed, it was a full-blown mess... drywall, carpet, the works.

Manual checks are great if you’re diligent, but life gets busy. I tell folks to use both: keep an eye out yourself, but have an alarm as backup in the spots where leaks would really hurt. Maybe not under every sink, but definitely near water heaters or behind appliances where you don’t look often. Just my two cents—sometimes that little beep is worth the hassle.

Title: Making sure your home’s pipes are up to code—how I do it

Manual checks are great if you’re diligent, but life gets busy. I tell folks to use both: keep an eye out yourself, but have an alarm as backup in the spots where leaks would really hurt.

That’s pretty much the approach I’ve landed on too, after seeing both sides of it. I used to be a bit skeptical about water alarms—felt like just another gadget to maintain, and yeah, those false alarms in the laundry room drove me nuts for a while. But then I got called out to a place where a tiny pinhole leak behind a washing machine had been dripping for who knows how long. The owner only noticed because the baseboard started warping. By then, the subfloor was toast and mold was already setting in behind the drywall. That job turned into a full gut and rebuild of half the basement. Not cheap.

I get why people hesitate though. In high-traffic areas or spots where you’re always mopping up spills (like under utility sinks), alarms can be more hassle than help. But anywhere you’ve got hidden plumbing—behind dishwashers, under water heaters, or tucked away in finished basements—it’s a different story. Those are the places where leaks can go unnoticed for weeks, and that’s when things get expensive fast.

One thing I’ve started recommending is pairing alarms with smart shutoff valves if you can swing it. Not everyone wants to deal with more tech, but if you’re already doing upgrades or bringing things up to code, it’s worth considering. The peace of mind is hard to beat—especially if you travel or have rental properties.

I still do regular walk-throughs myself (old habits die hard), but I don’t trust my memory as much as I used to. Life gets busy, like you said. A little redundancy isn’t such a bad thing when water damage is on the line.

Funny enough, I’ve found that once people see what even a “small” leak can do over time, they’re usually sold on some kind of early warning system—even if it means putting up with an occasional false alarm or two.

I get the appeal of “peace of mind” with smart shutoff valves, but I do wonder about the environmental impact of adding more electronics and batteries to the mix.

“Not everyone wants to deal with more tech, but if you’re already doing upgrades or bringing things up to code, it’s worth considering.”

Honestly, I’m with you on this—sometimes the best “upgrade” is just not letting your pipes turn into a science experiment. I swapped out some ancient copper lines for PEX last year and haven’t looked back. No batteries required, just fewer leaks. Smart valves are cool, but I’d rather spend that money on a good wrench and maybe a pizza after the job’s done.
