Installing and Connecting Vanity Sinks

Installing a vanity cabinet and sink is an excellent way to get more storage and countertop space out of your bathroom. Keep in mind your storage needs, size requirements/limitations, and personal tastes when selecting a vanity and consider asking professional advice fro company’s such as Archway Plumbers . The water lines should have caps soldered or glued and you’ll need to cut them off once the vanity is set. Measure the water and drain line locations on the wall. Transpose them to the back of the vanity and cut holes out for them. Cut the sink aperture if it isn’t already cut. Place the vanity over the lines and up against the wall. Check that the cabinet is sitting level/square and secure it in place.Connecting Vanity SinkCheck the manufacturer directions and connect the spout, water valves and handles on the sink. Link the supply tee and hose assembly to the spout. Our sink had braided steel lines that we looped to the valves and fastened them with coupling nuts. Attach the water supply lines to the valves if possible, to avoid reaching up under the sink later. Apply plumber’s putty (carried by any Archway Plumber ) around the drain fitting to form a seal and seat the fitting in the drain hole. Add a washer and slip nut on the bottom and tighten the fitting. Screw on the drain stopper coupling and its gasket so it lines up with the back of the sink. Feed the stopper’s slip arm through the sink and connect it to the stopper coupling. Push the stopper fully open and tighten the arm down. Flip the sink upright and set it in the cabinet. Remove any rag or cap plugging the drain stub. Glue a threaded adapter coupling onto the drain stub. Fit the trap and screw it to the adapter and sink drain. Tighten the sink water lines to their shut-off valves. Slowly open a shut-off, check for leaks, then check the other line. Fill the sink, check for leaks around the drain, then drain the water and check the waste line joints. This will also put water in the trap to stop sewer gases. Caulk around the rim of the sink to seal out water and to finish off the sink installation.
