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

I’m with you on the food coloring—blue or green is my go-to too, and I’ve never had any staining. That red stuff is brutal though.

Once had a tenant dump half a bottle of red food coloring in the tank... that took a while to clear out of the porcelain. Wouldn’t recommend going overboard.

The water meter trick is underrated. I started doing that after getting burned by a slow leak under the kitchen sink. The bill spiked, and I couldn’t figure it out until I finally crawled under there and found a tiny drip. Now I make it a habit to check the meter before bed if I hear anything weird or if the bill jumps. It’s kind of like playing detective, but with plumbing.

Listening for drips is hit or miss for me too. My house is old, and the pipes make all sorts of noises anyway. I’ve found that running my hand along the pipes, especially near joints, is the best way to catch something early. Even just a bit of coolness can mean trouble. Sometimes I’ll wrap a bit of tissue around a suspect spot overnight—if it’s damp in the morning, I know I’ve got a problem.

I’m curious—has anyone tried using those smart water sensors? The ones you put near your water heater or under sinks? I’ve read mixed reviews. Part of me likes the idea of getting an alert on my phone if something’s leaking, but I’m not sure if it’s overkill or actually helpful. Does it save water in the long run, or is it just another gadget to worry about?

Also, when you’re checking pipes for code compliance, do you focus more on visible stuff (like corrosion or loose fittings), or do you go deeper and check things like pipe insulation and venting? I always wonder if I’m missing something less obvious that could cause trouble down the line.

I get the appeal of smart water sensors, but honestly, I’ve seen more false alarms and dead batteries than actual leak catches with those things. They’re handy if you travel a lot or have a finished basement you really want to protect, but for most folks, regular checks and just paying attention to your bill does the trick. Sometimes all that tech just adds another thing to maintain.

On the code compliance side, I actually think people focus too much on what’s visible. Sure, corrosion and loose fittings are obvious problems, but I’ve found way more issues behind insulation or in venting setups—especially in older homes where things have been “fixed” over the years by different people. Insulation that’s gotten soggy or moldy can hide slow leaks for ages. And venting... don’t get me started. If it’s not right, you’ll get weird smells or even pressure issues down the line.

Honestly, nothing beats getting your hands dirty and poking around in the less obvious spots. That’s usually where the real surprises are hiding.

Couldn’t agree more—found a slow drip once that had been soaking the insulation for who knows how long. No sensor caught it, but my nose sure did when I peeled back the fiberglass... Sometimes you just gotta trust your gut (and your senses). Tech’s nice, but it won’t crawl behind your water heater for you.

Yeah, I’m with you on that—caught a tiny leak behind the washer last month, only noticed because the wall felt a bit damp. Sensors are cool, but honestly, I trust my hands and eyes way more. Sometimes you just gotta poke around, even if it’s a pain.

Totally get that. I found a slow drip under my kitchen sink once, only because I was reaching for a dropped spoon and felt the cabinet floor was damp. Sensors might catch stuff early, but I still end up crawling around with a flashlight every couple months. Ever tried those dye tablets for checking toilet leaks? I used one last week and was surprised how much water was sneaking through the flapper.
