The notes below assume that you have removed the old unit.For basins there is no need to make an overflow connection as this forms an integral part of the appliance. Feltham Plumbers can install basins. The waste fitting is ideally made into the basin with suitable rubber washers but where these are not available the joints can be made as follows:1). Apply a ring of plumber’s mate or silicone rubber to the underside of the section of the waste fitting that sits in the basin outlet. This joint to be successful the appliance must be absolutely dry, otherwise jointing mediums used will fail to stick to the porcelain.2). Place the waste fitting in position and apply a second ring of plumbers mate, silicon or a large rubber washer to the area around where the thread pokes through the waste hole of the appliance.3). Then put on a 32mm polythene washer.4). Finally, wind a large back nut onto the waste fitting, clamping the whole lot together to form a seal.5). To prevent the ways fitting turning in the basin while doing up the back nut, poke two screwdrivers through the slots or grates in the waste fitting and hold it secure. A Feltham Plumber carries the correct tools.Once the appliance is made up you can begin what is referred to as the “second fix”. First, secure the appliance into its location, ensuring it is adequately supported and level. The top of the appliance is plugged in level as the gradient towards the waste is built into the design of the appliance. Extra Info:For plastic bath installations there are additional wall fixing clips, provided with the appliance designed to prevent the bath sagging due to the weight of water as it fills.“
