Although undermount sinks seem to resist gravity, they are only slightly different to put in compared to topmount sinks. Clips which hold the sink tight from the countertop are concealed underneath the counter. Into the stone with epoxy, the bolt part of the clips are glued with granite counters ; you should not require new hardware. Switch the water supply off before substituting the sink, and disconnect the pipes or hire a plumber to do this for you. The sink will soon be out of commission to time that is glue, so plan accordingly.
Lay a 4-foot-long 2-by-4 flat.
Press the launch button or trigger on an adjustable bar clamp. Slide the portion of the clamp along the pub before the clamp is totally open. A half of the clamping mechanism mounts onto one end of the pub, and another half of the mechanism slides adjusting to the thickness of these objects clamped together.
Slip the fixed portion of the bar clamp through the sink’s drain opening. Until the fixed portion of the clamp sits against the bottom of the sink, pull up on the pub.
Move the required before it butts against the clamp bar.
Squeeze the clamp’s activate , moving the part of the clamp down the bar tightens from the 2-by-4’s top. Fit another clamp during the second drain, if the sink is design with two drains and then twist it as you did with the drain.
Twist the blade of a utility knife into the seam between the top edge of the sink and the granite countertop’s bottom. Pull the blade through the seam around the whole sinkor caulk that bonds the sink using the countertop.
Locate the mounting clips under the counter round the perimeter of the sink. Twist the wing nuts or hex nuts onto the bolt part of the mounting clips a small wrench or counterclockwise with pliers. Remove and the metal bar-shaped clips in the bolts. Do not remove mounted under the countertop. Save the nuts and clips, as you may reuse them.
Request a helper to hold the base of the sink. Publish the trigger remove the straps get rid of the sink and lower the sink down.
Scrape on the sheeting or silicone off the bottom of the counter sink opening using a scraper blade. Wipe off the scraped area with a clean, dry rag.
Fit the sink within the cupboard and also ask a helper to lift it high enough to fit the bar clamps since you did with the sink. Reposition the 2-by-4 across the sink opening and tighten down the clamps before the sink is close, but not touching the bottom of the granite counter.
Apply silicone glue around the top edge of the sink.
Align the sink with the perimeter of the sink opening at the countertop. Until the spout fits comfortable, but not tight tighten the clamps.
Replace each sink mounting clip and nut around the perimeter of the bottom of the sink.
Leave the pub clamps and 2-by-4 in place for 24 hours, then get rid of the bar clamps and 2-by-4 and reinstall the pipes.
