    Tank to Bowl Toilet Kit: https://amzn.to/2mj9irL

    The dreaded slow drip from a toilet bolt… We will show you how to fix a leaky toilet by replacing the hardware that holds the toilet tank to the toilet bowl.

    This can be a hassle to diagnose since there are 3 (or sometimes 4) connection points on the bottom of the tank. Our suggestion is to pick up a kit that contains a new gasket, bolts and washers to replace all the connection points. In our case, we had a slow drip coming from one of the bolts.

    Any DIYer can learn how to fix a leak from the toilet hardware as long as you have a little patience and are careful not to over-tighten the bolts on the porcelain.

    Here are the steps to fix leaking toilet hardware:

    1. Shut off the water to the toilet
    2. Drain the toilet tank by flushing
    3. Use a wet vacuum or a sponge to dry the tank
    4. Remove the water supply hose
    5. Unscrew the toilet tank bolts
    6. Lift the tank off the toilet bowl
    7. Remove the old gasket
    8. Install the new gasket
    9. Feed the bolts through the toilet tank with a rubber and metal washer
    10. Add a rubber washer, followed by a metal washer to the underside of the tank
    11. Tighten the tank bolt and nut assembly
    12. Align the toilet tank above the toilet bowl and lower into place
    13. Add a rubber washer, followed by a metal washer, followed by the metal nut
    14. Use a wrench to tighten the bolt
    15. Reattach the water supply hose
    16. Open the water supply valve
