    Default Underpowered Flush

    A contractor that did some shoddy work on my bathroom installed a korky universal toilet repair kit. Now I have to hold down the handle extra long to get a full flush.

    How do I make the necessary adjustments?

    The flapper may not have been trimmed.

    Here are the instructions for that. You should be able to fix it with a pair of scissors and just a small bit of time.

    Default Small change

    Now that I look at it, he didn't change the flapper. He changed the fill valve. (I think that's the right terminology)

    Is this situation fixed by adjusting the fill valve or the flapper?

    Probably both.

    You need to adjust the chain on the flapper. If you push the handle quickly, the flapper might be slapping back down under the force of the water.

    Secondly, you might want to make sure that your fill valve is adjusted correctly so that the tank is filling to about one inch below the overflow tube (I always leave a generous gap for future wear of the valve). You might not be getting a full tank to flush with.
