my shower's gone rogue and sprays everywhere but down

I hear you on the brass vs. PEX debate. I’ve had my fair share of “surprise showers” from crimp rings that didn’t quite hold up, especially in places where you just can’t see what’s going on until it’s too late. Brass is old school, but there’s a reason it’s stuck around - once you get it threaded right and sealed up, you can pretty much forget about it for decades.

If your shower’s spraying everywhere but down, here’s my quick-and-dirty checklist before you start tearing into the wall:

1. Check the showerhead itself. Sometimes mineral buildup or gunk messes with the spray pattern. Unscrew it, soak it in vinegar, and give it a good scrub. You’d be surprised how often that fixes wild spray issues.

2. Look at the threads and washers. If you see any crusty white stuff (mineral deposits) or the rubber washer looks chewed up, swap it out. A $0.50 washer can save you a lot of grief.

3. If you’ve got one of those adjustable spray heads, sometimes the internal parts get jammed or worn out. At that point, it’s usually easier to just replace the head.

4. For anything behind the wall, I’m with you - brass all the way. But I’ll admit, PEX is a lifesaver when you’re working in tight spots or retrofitting old lines. Just double-check those crimps and use a good quality tool... learned that lesson the hard way after a midnight leak call.

Funny enough, I once had a client who thought their shower was haunted because it would randomly spray sideways at full blast. Turned out, some Teflon tape had gotten loose inside the head and was blocking half the holes. Quick fix, but they still swear their bathroom’s cursed.

Anyway, don’t overthink it - start with the simple stuff before you break out the pipe wrenches. Most of the time, it’s just buildup or a tired washer causing chaos.

I get the appeal of brass, but I’d actually challenge the idea that it’s always “set and forget.” In older homes, I’ve seen corrosion inside brass fittings that went unnoticed for years, leading to some pretty nasty leaks behind the wall. PEX might not have the same track record, but with proper installation and regular checks, it can be just as reliable - plus, it’s less prone to freezing damage in my experience.

That said, your checklist is spot on for surface-level issues. Just don’t underestimate what’s happening out of sight. A small leak can turn into a big headache if you’re not careful.

Definitely hear you on the “set and forget” myth. I’ve seen plenty of brass stuff that looked fine until you peeked behind the wall - then it’s a science experiment. PEX isn’t perfect, but regular checks go a long way. Nice catch with the Teflon tape, by the way... those little things can throw you for a loop.

I’ve been burned by that “set and forget” mindset too many times. The last time I pulled out a faucet, the brass looked pristine on the outside, but the inside was basically a petri dish. It’s wild how something can look totally fine until you dig a little deeper. I get why folks like PEX - less fuss, fewer corrosion worries - but it’s not like it’s immune to issues either. I had a PEX joint start leaking behind a wall because the clamp wasn’t seated right. Didn’t notice until the drywall started to bubble. That was a fun weekend project...

Teflon tape is one of those things that seems so minor, but if you miss a wrap or two, you’re in for a world of frustration. I’ve learned to double-check every threaded connection, even if it feels like overkill. The cost of a roll of tape is nothing compared to tearing out tile or replacing drywall.

Honestly, I think a lot of these problems come down to regular maintenance and just keeping an eye out for the weird stuff. I get wanting to save money (I’m always looking for ways to avoid calling in a pro), but sometimes it’s worth spending a little extra up front - like on decent shutoff valves or better fixtures - just to avoid headaches later. Cheap stuff almost always bites you in the end.

One thing I’ve started doing is keeping a little log of what I’ve checked and when. It sounds kind of obsessive, but it’s saved me more than once from forgetting about a slow drip or a loose fitting. Not saying everyone needs to go that far, but if you’re on a budget and want to avoid big surprises, it helps.

Anyway, showers that spray everywhere but down are the worst. Sometimes it’s just a clogged head or bad gasket, but other times it’s a sign something deeper is off. Either way, ignoring it never seems to work out in the long run...

You're right on the money - it's always the little stuff that comes back to haunt you. I can't count how many times I've thought, "Eh, that's tight enough," only to be staring at a slow drip an hour later. That logbook idea is actually pretty sharp. I used to think it was overkill, but after replacing the same shutoff valve twice because I forgot which one was leaking, I've come around.

As for showers spraying everywhere, sometimes it's just mineral buildup or a worn gasket, but like you said, ignoring it never ends well. I had one where the arm had a hairline crack - looked fine until water started shooting sideways. Lesson learned: take things apart before assuming it's just a clogged head.

Spending a bit extra on quality parts up front really does pay off. Cheap fixtures look nice for a year, then you’re stuck with mystery leaks and weird noises. Maintenance isn't glamorous, but it beats ripping out soggy drywall.
