Low shower pressure: 6 checks before you call maintenance

Low pressure is often caused by buildup in the showerhead or a partially closed valve. These checks are renter-safe and don't require opening walls or doing plumbing work.

Important: These guides focus on low-risk, reversible steps. If your lease forbids a modification (or the task involves gas/electrical/structural work), stop and contact maintenance.

6 quick checks (in order)

Check other faucets: if the whole unit is low, it may be a building issue.
Look for a flow restrictor (some showerheads have them by design).
Clean the showerhead face: scrub mineral deposits on nozzles.
Vinegar soak: bag + diluted vinegar on the head for 30–60 minutes, then rinse.
Check the hose (if handheld): kinks or a clogged screen can reduce flow.
Check the tub diverter: if water is leaking out the tub spout while showering, the diverter may be failing.

When to call maintenance

Sudden major drop across the unit.
Pressure varies wildly with temperature changes.
Visible leaks behind the shower wall or around fixtures.
