The order of sink and faucet hookups on install day

The sink is supposed to go in last, since it is the last thing a homeowner looks at. Often it goes in first. On a stone top the undermount sink is glued to the underside before the slab is set, and countertop installation austin tns media group sets the order deliberately, because a sink fitted in the wrong sequence ends up crooked or leaks at the rim. Install day for a countertop in Austin, TX follows a fixed order for that reason.

Template and sink cutout first

The sink is on site before the template is cut. The installer needs the exact sink, not a catalogue drawing, because the sink cutout is traced from the real flange or rim. A digital template records the wall, the cabinet edge and the cutout together. The fabricator then cuts the opening with a bridge saw and finishes the edges by hand.

Mounting an undermount sink

On install day the sink goes on the slab upside down on a pair of blocks. Epoxy or silicone is laid along the rim, the clips are set, and the sink sits tight to the underside of the stone while the adhesive cures. Granite, quartz and porcelain all take the same method. Marble and soapstone need the installer to check the sink reveal, the small ledge between the opening and the bowl, so the stone edge does not chip when a pot hits it.

Setting the slab

Once the sink is bonded, the slab is carried in, set on a bed of silicone dots on the cabinet tops, and pressed down. A seam between two pieces gets colour-matched epoxy and is pulled tight with suction cups. The installer checks level once more across the seam, before the glue sets, since a lip at a seam is difficult to fix afterwards.

Faucet and drain

With the top set, the faucet goes through its hole. Most faucets are easier to attach before the slab is dropped, with the top upside down, but the final tightening happens in place. The drain line comes next, then the supply lines, and the angle stops are opened slowly, one at a time, while someone watches the joints with a flashlight. A slow leak shows up as a bead of water at a nut within a minute or two.

Disposal, dishwasher and cooktop

The garbage disposal clamps to the sink flange and is connected to the drain last. The dishwasher gets its drain hose looped high, tied to the underside of the stone, and then its water line. A cooktop or slide-in range goes in only after the cutout edges are sealed. A cabinet that was shimmed up may change the dishwasher height by a fraction, which a thick slab then makes obvious. Whenever an older house near Zilker has a worn supply line, the crew swaps in a new flexible hose, which takes minutes now and avoids a flood later.
