What to do if…
your shower or tub will not turn off and water is running continuously

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Move away from hot water and standing water, then shut off the nearest safe water valve you can identify. If you cannot stop the flow quickly, call building maintenance, your landlord, a licensed plumber, or your local water utility for emergency shutoff guidance.

Do not do these things

  • Do not leave the water unattended while you search for help; a tub can overflow or water can spread into walls, floors, or lower rooms.
  • Do not use extreme force, pipe extenders, or long tools on a stuck valve.
  • Do not take the shower handle, faucet, cartridge, or diverter apart while water is still running.
  • Do not touch chargers, hair dryers, extension cords, outlets, or electrical equipment near wet floors.
  • Do not stand under very hot running water; step away and keep children and pets out of the bathroom.
  • Do not use the outside meter shutoff unless your water utility says you may and you can do it safely.

What to do now

  1. Make the bathroom safer.
    Point the shower head into the tub if you can do that without getting burned. Close the shower curtain or door to reduce splashing. Keep children and pets out, and step carefully if the floor is wet.

  2. Try the tub or shower shutoff only if it is obvious and reachable.
    Some tubs and showers have hot and cold shutoff valves behind an access panel, in a nearby closet, in a basement or crawlspace below, or on the opposite side of the wall. If you see them, turn them slowly clockwise. If you do not see them within a minute or two, move on.

  3. Shut off the home’s main water valve.
    Look where the water line enters the home, near the water heater, in a basement, crawlspace, garage, utility room, or near the water meter. A wheel-style gate valve generally closes by turning clockwise. A lever-style ball valve generally closes by turning the handle a quarter turn so it is across the pipe, not in line with it. If the valve will not move with normal hand pressure, stop trying to force it.

  4. Check whether the flow is slowing.
    After a shutoff valve is closed, open a lower-level faucet briefly if one is nearby and safe to reach. The shower or tub may keep trickling for a short time while the pipes drain.

  5. If hot water was running, treat scalding as the immediate risk.
    Keep people away from the stream and do not test the water with your hand. Tell maintenance or the plumber that very hot water may have been running continuously.

  6. Call the right help.
    If you rent or live in an apartment or condo, call building maintenance, management, or your landlord and say: “The tub or shower will not shut off. I have shut off water at [fixture or main],” or “I cannot shut off the water.” If you own the home, call a licensed plumber. If the main valve is stuck or you cannot stop active flooding, contact your local water utility for emergency shutoff guidance.

  7. Limit damage while you wait.
    Use towels only if you can stay clear of hot water and electrical hazards. Move nearby items out of the splash zone. If water is reaching outlets, light fixtures, electrical panels, or a ceiling below, keep people out of that area and do not touch electrical equipment while standing on a wet floor.

What can wait

  • You do not need to identify the exact failed part right now.
  • You do not need to decide whether it is a cartridge, diverter, mixing valve, handle, or tub spout problem.
  • You do not need to shop for replacement fixtures or compare repair quotes until the water is stopped.
  • You do not need to do deep cleanup before the flow is under control and the area is safe.

Important reassurance

A stuck shower or tub valve is upsetting, but the first goal is simple: stop or isolate the water. Once the flow is controlled, a plumber or maintenance person can usually diagnose the failed part without you needing to solve it first.

Scope note

These are first steps to reduce immediate water damage and safety risk. Later repair decisions may need a licensed plumber, building maintenance, your water utility, or an electrician if water reached electrical systems.

Important note

This is general information, not professional plumbing, electrical, gas, insurance, legal, or safety advice. If you cannot safely stop the water, or water is affecting electrical systems, another unit, or a ceiling below, get urgent professional help.
