Frequently Asked Questions

  1. Can you flush poop with a bucket of water?

    Yes you can. Just fill a bucket of water and pour it fast in the toilet bowl. Remember that this action of flushing creates a siphoning action of the toilet at the P-trap.

    If you simply pour water in the toilet bowl casually, then the siphoning action will not be triggered. Otherwise the bowl will fill entirely which will be a big mess to deal with.

  2. Can you flush the toilet without power?

    The answer is yes and no. It is because it depends on your toilet type. If you have a gravity flush toilet then your toilet will perfectly work without electricity. If you have a pressure-assisted toilet, you will need electricity for your toilet to work.

    Tankless toilets also need a connection of electricity to work. They use water supplied by the pump. The pump needs electrical connection to compress air. The under pressure water is one of the advantages of tankless toilets.

  3. How to flush a tankless toilet without water?

    A tankless toilet uses water directly from the water lines under high-pressure. Like other toilets which work using power, this toilet also needs an electrical supply for the pump which delivers the water to the bowl at high-pressure. 
    Method:
    Fill a bucket with water.
    Lift up the toilet lid and seat.
    Pour the water inside the toilet bowl fast enough to create a siphoning action.
    Keep away your face from the bowl to avoid splashing on your face.

  4. Can You Flush The Toilet When Water Is Off?

    After one flushing when your toilet tank’s shut off valve is off, your toilet tank is still full of water since it refills immediately after flushing. Therefore, you can use the toilet flush a second time. If you want to turn on your water supply, locate a rear wall on the rear wall, on the left-hand side of your toilet.  Turn on the wall counterclockwise.

    If the shut-off valve is open and your tank is not filling with water. Check that your main shut-off valve is open. This is mostly a red wheel located next to your water meter. If your tank is still not filling up with water, this could be a problem with the fill valve.

  5. Toilet Won’t Flush With a bucket Of Water?

    If you are using a bucket of water to flush your toilet, it could be a problem with your toilet that it is clogged or you are pouring water too slowly. In order to flush a toilet using a bucket of water, try to dump all the water at once. This sudden release of water in large amounts initiates the siphoning action in the toilet bowl, that flushes everything.

    If the problem persists in your toilet, then your toilet is clogged. Try using a plunger or toilet snake to close your toilet and then try again and again or call a professional plumber.
