There are many different types of basin waste fittings, some need a plug to keep the water in the basin and others are automatically sprung and others have a lever which sits at the rear of the tap. The majority of basin waste fittings however are all fitted in a similar way. Edgeware Plumbers can supply and fit all types of appliances. Below is a brief guide to fitting a waste outlet for a basin, with the old one already removed. A new waste fitting should be fitted into the basin with the correct rubber washers, however if you dont have them, this joint can be completed by following the guide below:Place a ring made of plumbers mate or silicone rubber to the underneath of the part of the waste fitting that is fitted in the basin outlet. The appliance needs to be dry for the best result otherwise any jointing compounds that you use used will not adhere to the porcelain. An Edgeware Plumber can fit basin waste fittings.Position the waste fitting and place a second ring of plumbers mate, silicon or a large rubber washer around the threaded area that is visible at the hole in the appliance. Now fit a 32mm polythene washer.Fit a large back nut on the fitting, which will compress and seal the fitting. Make sure the fitting doesnt turn when tightening the back nut by putting two screwdrivers through the slots in the fitting to hold it still. The final thing to do is the second fix. This fix is to make sure that sure that the appliance is level, fixed securely, and supported, it also makes sure that all the pipework is concealed and the basin looks good. The slope is already integral to the basin.
