  2. Siamp Bottom Basket 48mm ATS5025

    This basket takes the Siamp flush valve but has a smaller thread size which makes it compatible with cisterns that have a smaller than standard hole in the bottom. Normal size is 63mm but if your cistern has a hole between 49 and 56mm diameter in the bottom and a height of between 320mm and 420mm then you can use this basket in conjunction with a Siamp flush valve (CLICK HERE FOR FLUSH VALVE). 

    Note, this is only an option if the hole in the top of your cistern is between 39mm and 45mm and is directly above the bottom hole.
