Had a place once where someone used PVC for hot water lines—didn’t even last a year before it started leaking. I get the urge to patch things up quick, but those shortcuts always come back to bite you. It’s wild what people think will hold up behind drywall. Sometimes I wonder if they just hoped nobody would ever find it...
PVC for hot water is a classic rookie mistake—seen it more times than I can count. If you’re dealing with water pressure issues, check for those hidden “fixes” first. Sometimes it’s just a bad joint or the wrong pipe type causing all the headaches. If you’re opening up walls, look for CPVC or PEX on hot lines, not regular PVC. It’s wild what gets buried back there...
Had a similar mess in my last place—some genius ran PVC right up to the water heater. Ended up with all kinds of pressure drops and weird noises. Ever run into those old galvanized pipes mixed in too? Those things are a nightmare for pressure.
Had to deal with a tangle of old galvanized pipes in my first house—total headache. The water pressure was so bad, I could barely rinse shampoo out of my hair. I tried flushing the lines, but those pipes were just too corroded. Ended up replacing them with PEX, which honestly made a huge difference and felt like a greener choice too. It's wild how much those old materials can mess with something as basic as water flow.
You made the right call swapping out those old galvanized lines. Once corrosion sets in, flushing rarely does much—sometimes it even makes things worse by loosening up more debris. PEX is a solid upgrade, especially if you want to avoid future headaches. It’s wild how much a simple material change can improve daily life... I’ve seen folks try patch jobs, but honestly, full replacement is usually the only way to get real water pressure back.
