Toilet Care
A friendly, practical guide to keeping toilets running right, catching leaks early, and knowing just what to do when something goes wrong.
Where to start
- Toilet overflowing right now?
Take a breath and don’t flush again. See if a toilet overflows or leaks.
- Hear a hiss in the night?
Try the dye test to check for a silent leak.
- Just moved in?
Find the shutoff valve behind each toilet, then work through the toilet checklist.
The short version
Toilets are simple machines, and most problems start small and quiet. A few minutes of attention keeps them working well and saves water.
Know where the shutoff valve is behind each toilet. Turning it clockwise stops water to the tank in seconds.
A toilet that runs, refills on its own or needs a jiggle is leaking. Try a dye test: a few drops of food coloring in the tank, wait about 10 minutes, and look for color in the bowl.
Only flush pee, poop and toilet paper. If a toilet wobbles, leaks at the base or clogs often, please share it early so it can be fixed.
Rules about repairs differ from place to place, so we’d gently encourage a quick look at the rules where your home is. If you ever have questions, we would love to help.
Four simple rules
- 1Know where the shutoff is
Every toilet has a small valve on the wall or floor behind it. Turning it clockwise stops water to the tank in seconds.
- 2Listen for running water
A toilet that hisses, trickles or refills on its own is leaking. It can waste a surprising amount of water, quietly.
- 3Only flush the three P’s
Pee, poop and toilet paper. Wipes, even ones labeled flushable, and other items belong in a trash can.
- 4Share small problems early
A running tank, a wobble or a little water at the base is usually a quick fix when it is caught early.
Toilet checklist
From the guide’s own checklist. Tick each one as you go. Your ticks stay on this device. These are examples; your home may need others.
All done. Every toilet is ready to stay quiet and easy to live with.
If a toilet overflows or leaks
- If the bowl is rising, take a breath and don’t flush again.
- Lift the tank lid and gently press the flapper down to stop more water from entering the bowl.
- Turn the shutoff valve behind the toilet clockwise until it stops. If it is stuck, don’t force it with tools.
- Lay towels down, put on gloves, and try a flange plunger with slow, firm strokes.
- If water is leaking from the tank, the valve or the base, keep the water off and dry the floor right away. Water spreading toward other rooms or through a ceiling is urgent.
- Share what happened in writing, with photos, so it can be repaired.
You did exactly the right thing.
The dye test
- Put a few drops of food coloring in the tank.
- Wait about 10 minutes without flushing.
- Look in the bowl. If color shows up, the flapper is leaking.
- Flush when you are done, and share a leak in writing.
A running toilet is a leak, and the fix is usually small.
