A:  Hi Bamagirl, this is Lisa with Kohler Co. I am glad to answer your question. If there was not a previous flow restrictor, it is recommended to start with the blue one. Each colored restrictor allows a different percentage of restriction to control the refill rate of water into the toilet bowl. When a conventional toilet is flushed, the bowl simultaneously refills with water as the tank refills. However, the tank is much larger than the bowl and typically fills at a significantly slower rate. The flow restrictor restricts the flow of water refill into the bowl during tank refill so the bowl fills in about the same period of time as the tank. If the blue one does not allow this to happen, you will want to try other colors until that fill speed is reached. Thank you for choosing Kohler.
