Shower Head Leaking? It's Usually a $3 Part

A dripping shower head is rarely the shower head. Here's how to tell whether you need a fifty-cent washer, some plumber's tape, or a new valve cartridge.

A shower head that drips after you've shut the water off is one of those sounds you stop noticing and then can't stop noticing. It's also, in most San Diego homes, a genuinely small fix — as long as you identify which of two very different problems you actually have.

First, Figure Out Where It's Leaking

This determines everything, so look carefully before you buy anything.

If water drips from the face of the shower head after you turn the water off, and stops within a minute or two, that's just residual water draining from the head and the arm. Completely normal. Nothing to fix.

If it keeps dripping for more than a few minutes, or drips continuously, the shut-off valve inside your faucet handle isn't sealing. The shower head is innocent — the problem is upstream, in the valve.

If water is leaking from the joint where the head screws onto the pipe arm, that's a seal issue at the connection, and it's the easiest fix of the three.

Fix 1: Leaking at the Connection

This is a ten-minute job with no shut-off required.

  1. Unscrew the shower head. Turn it counter-clockwise by hand. If it's stuck, wrap the connection in a cloth to protect the finish and use an adjustable wrench.
  2. Check the rubber washer inside. Look inside the shower head's threaded collar. There's a small rubber washer or O-ring in there. If it's cracked, flattened, or missing, that's your leak. Replacements cost a couple of dollars at any hardware store — bring the old one to match the size.
  3. Clean the threads. Wipe old tape and mineral buildup off the threads of the shower arm with a rag. In our harder-water inland neighborhoods — Rancho Bernardo, Scripps Ranch, Poway — there's usually a chalky ring to scrape off.
  4. Wrap with plumber's tape. Wind PTFE tape clockwise around the arm threads, three or four wraps. Clockwise matters: wrapping the other way makes the tape unwind as you screw the head on.
  5. Reattach hand-tight, plus a quarter turn. Don't crank it. Overtightening cracks plastic fittings and distorts the washer you just replaced. Run the shower and check.

Fix 2: Continuous Drip From the Head

If the head keeps dripping long after shut-off, the valve cartridge inside your faucet handle has worn out. The rubber seals inside it harden with age and mineral exposure and stop sealing completely.

Cartridge replacement is a real but manageable job. You'll need to shut off the water to the shower — sometimes at a dedicated valve behind an access panel, often at the main. Then remove the handle, pull the old cartridge, and install a matching replacement.

The critical part is getting the right cartridge. They're brand and model specific, and there are dozens. Take the old one to the store, or photograph the faucet brand marking on the handle or escutcheon before you start. Many manufacturers will send replacement cartridges free under a lifetime warranty if you call them.

Why the Drip Is Worth Fixing

A shower head dripping once per second wastes somewhere in the range of 1,500 gallons a year. In a region with tiered water rates, that shows up on the bill. And a valve that no longer seals tends to get worse rather than stabilize.

There's also the mineral issue. Constant dripping over a shower floor leaves a hard-water stain that etches into the finish over time, and that's a lot harder to undo than the leak itself.

While You Have It Off

If you've unscrewed the shower head anyway, soak it in white vinegar for an hour. San Diego water leaves calcium deposits in the spray nozzles that reduce pressure and throw the spray pattern off. A soak and a scrub with an old toothbrush usually restores it. It's the cheapest pressure improvement available.

Let Our Team Handle It

Replacing a washer is easy. Diagnosing whether you need a washer or a cartridge — and then finding the right cartridge for a fifteen-year-old faucet — is where an afternoon disappears. For Livd members, this is a standard visit task: we'll identify which it is, bring the part, and handle the water shut-off.

If it turns out the valve body itself is failing rather than the cartridge, that's licensed plumbing work, and we'll coordinate a vetted plumber from our network rather than leaving you to find one.
