You shut the shower off, towel off, and you’re halfway through brushing your teeth when you hear it. Drip. Then another. By the time you’re in bed it’s still going, and it’ll be going at 3 a.m. too. A leaking showerhead rarely floods anything, which is exactly why people let it ride for months. Here’s what that drip actually costs in Northfield, and what’s usually behind it.
Measure It Before You Worry About It
The national numbers get thrown around a lot. The EPA’s WaterSense folks put a showerhead dripping 10 times a minute at more than 500 gallons a year. Useful, but your drip isn’t their drip. So measure your own leaking showerhead.
Set a measuring cup under the head right after a shower and check it an hour later. Say you’ve caught one cup. That’s 24 cups a day, or a gallon and a half, and roughly 45 gallons a month. If it’s a thin stream instead of drops, multiply that several times over.
Honest caveat: a few drops for the first couple of minutes isn’t a leak. The head holds water and gravity empties it. I tell people to give it 15 minutes. If it’s still dripping after that, the cup test is worth doing.
The Drip Usually Starts Behind the Wall
With a leaking showerhead, the head is usually just the exit. The real problem sits behind the wall, in the valve cartridge or the rubber seats and springs on an older two-handle setup. When those wear, the valve can’t shut off completely, and water creeps out the lowest open point.
Northfield’s hard water speeds that up. Scale builds on the cartridge until the seals stop seating flat. That’s your slow weep. If your house is older and still has a two-handle valve, those seats wear out on a fairly predictable schedule.
One quick tell: if the drip runs warm, the hot side is the likely culprit. Not a guarantee. Just where I’d look first.
What You Can Fix Yourself, and Where to Stop
Some of this is fair game. A crusted head can soak in white vinegar overnight, and that’ll clean up the spray. It won’t stop a drip, though, because the drip almost never starts in the head.
The valve is where I’d tell most people to stop.
Cartridges are brand-specific, and a Moen 1222 won’t fit a Delta body no matter how hard you push. Pull the wrong one, or strip a stem on an older valve, and you’re shutting off water to the whole house while you hunt for parts.
Replacing the valve body is a different job again. Minnesota’s plumbing code requires new shower valves to be anti-scald, pressure-balancing or thermostatic, and that kind of work generally needs a permit.
Why Waiting Costs More Than Water
The water bill is the small part. Forty-five gallons a month barely moves it. What worries me is the valve behind it.
A homeowner a few blocks from Carleton called us last winter about a leaking showerhead she’d been ignoring since summer. By then the drip was a trickle, and the cartridge had scaled so badly it snapped coming out. A cartridge swap that normally takes 45 minutes to an hour turned into a valve replacement, with her bathroom wall open for the afternoon.
Worn valves don’t heal. They just get harder to pull.
If the handle’s getting stiff, or the temperature swings mid-shower, the valve is telling you the same thing the drip is.

Questions We Get About Shower Drips
Is it normal for my shower to drip after I turn it off
For a few minutes, yes. The head holds a bit of water and it drains out. If it’s still going 15 minutes later, that’s a leaking showerhead, and the valve’s the usual suspect.
Will a new showerhead fix the dripping
Probably not. The drip is almost always coming from the valve, and a new head just gives it a nicer place to exit. I’d spend that money on a cartridge.
Does hard water make a leaking showerhead worse
It does. Northfield’s water is hard, and the scale it leaves on cartridges and seals is one of the most common reasons we find a valve that won’t fully close. A softener slows that down. It won’t fix a cartridge that’s already scaled.
Do I need a permit to fix my shower valve in MN
Swapping a cartridge usually doesn’t. Replacing the whole valve generally does, and the new one has to meet Minnesota’s anti-scald requirement. Check with the city before you open a wall, or have your plumber pull it.
Is a leaking showerhead an emergency or can it wait
A slow drip can wait a few days. Water showing up on the ceiling below, or a drip that’s turned into a steady stream, can’t. Either one means the valve is failing faster than usual or something’s leaking inside the wall.
Run the cup test tonight. If you catch less than a tablespoon, forget I said anything.
