Hi, this is Nicholas Iarocci, The Home Source Guy, President and Owner of Source Development Inc., a residential and commercial construction company in Garnerville, New York and this is how to install a bathroom sink. So we're gonna start by trimming out our counter top. So if you notice our pre-drilled counter top has a 4 inch center so we've got a faucet that matches our application. It's either 4 or 8 inches unless it's a custom application. So I'm placing the faucet through the holes. I'm gonna install our retention clip and nut and it's always a good idea to mount the faucet on the counter top before you install it in the vanity. Take our channel locks and tighten. We're gonna check to make sure that the faucet is centered and that the gas gets properly placed underneath it. And once you've made sure that the gas gets in the proper position and that the faucet's in the proper position and centered above the drain hole we're gonna continue tightening the back retaining nuts. Now we're gonna add our supply tubes. So once they're finger tight we're gonna just take our channel locks, go a quarter turn past. So now we're gonna install our drain popup and in our case it's a plastic popup. It can come in metal or plastic. We're gonna loosen the top of the popup and on the outer perimeter we're gonna install plumbing putty. Install, push down, insert the opposite end through the back and then tighten the retention nut on the popup stopper. Just snug, you don't want to over tighten it but you want to make sure it creates a waterproof seal. You're gonna remove the retention nut on the popup drain. Insert the lever through the retention nut and then reinstall the rod through the popup drain and tighten the retention nut. I'm gonna insert our popup drain. We face that tab towards the faucet whereas that rod is connected to the popup drain. We're gonna insert the rod through the lever. The back of the faucet. Insert the rod into the extender. I'm gonna pick the second hole from the bottom. First our retention clip gets installed, then the extension, and then the other end of the retention clip to hold it in position. I've tested the operation of our lever to make sure that the operation is smooth and I'm gonna tighten. So our sink is completely trimmed and ready for installation now. We're ready to install. We're gonna connect our supply lines. I'm gonna start off with our hot side and it's finger tightened. To our cold side supply, again these are no burst pipes so they've been finger tightened and we're gonna give them a quarter turn with our channel locks. So we're gonna work on the drains. We're gonna start to attach the drains. This is p-trap. It comes in 2 separate pieces. I'm gonna be placing them together. I've already rough cut the length of our p-trap for our particular configuration so I'm gonna install the retaining nut and nylon washer. I'm gonna install the drain pipe. So if you notice there's a gap between the tail piece and the p-trap. So we're gonna need an extension tail piece installed which is what this is. So we're gonna lay it next to the pipe, size it so we know it's gonna gap over here. We're gonna mark it. So once I've marked our tube I'm gonna cut it. So I've cut our extension tail piece and I'm gonna install it now. There's a retainer nut and on this particular tail piece we're going from an inch and a half to an inch and a quarter so you need the proper washer. I'm gonna insert the retention nut in the nylon washer. I'm gonna loosen up our p-trap and I'm gonna install the extension tail piece. I'm gonna install another retention nut and gasket, washer, and this was a bathroom sink replacement.
