When multiple people want to get prepared to go to school or work at exactly the exact same time, the bathroom may be a busy location. Installing a two-sink vanity can help alleviate the log jam. The 2 sinks at the one vanity are connected to the exact same supply and drain lines, so there’s absolutely not any requirement for any additional plumbing rough-in to the house, as each the connections are completed inside the vanity cabinet.
Turn off the water main to the home, then turn a faucet on the ground floor of the home to alleviate pressure to the water lines.
Loosen the coupler on one of the present water valves having an adjustable wrench while holding the valve in position with a second flexible wrench. Pull the valve off the tubing, followed by the ferrule and the coupler. Slide a coupler from a dual-outlet provide valve onto the tubing followed by the ferrule from the new valve. Position the new valve over the end of the tube, and tighten the coupler having an adjustable wrench while holding the new valve with the other wrench. Repeat with the other supply valve.
Place a new faucet into the mounting holes of one of those 2 sinks at the two-sink vanity top. Thread the mounting nuts onto the forehead under the sink to fasten the faucet to the sink. Tighten the nuts with a massive pair of slip-joint pliers. Connect one end of a water supply line to the left (warm water) nipple of the faucet with an adjustable wrench, then connect the other end of the line to one of these 2 outlets on the dual-outlet valve on the left (for the warm water feed) that you previously installed. Tighten the coupler having an adjustable wrench. Then connect the right-side provide line to one of those two nipples on the cold water valve inside the vanity.
Install the faucet on the next sink in exactly the exact same manner as the first.
Connect the T-fitting to the tailpiece closest to the drain, with the side inlet of the T-fitting pointing toward the drain of the next sink. Connect the P-trap to the drain line at the wall and the bottom of the T-fitting, and tighten the couplers by hand to lock the P-trap set up. Hold the elbow and the extension line involving the next sink’s drain and the T-fitting, and mark the extension where it ought to be trimmed to fit to the T-fitting. Cut the extension with a hacksaw at the mark, then slip the cut end into the T-fitting and the elbow to the tailpiece of the next sink. Twist the coupler on the T-fitting and the elbow to fasten the line. Tighten all the drain couplers with a pair of slip-joint pliers.
Turn the water main to the home followed by the two dual-outlet provide valves inside the vanity. Then turn on the 2 faucets and watch beneath the sink to get any leaks.
