A new faucet can update your bathroom with minimal effort and expense. It only takes a few hours and can be easily set up over the weekend.
Steps
Method 1 of 4: Installing a mixer

Step 1. Measure the distance between the holes in the sink where the handles are installed with a centimeter or tape measure to determine the type of mixer purchased

Step 2. Turn off the hot and cold water supply through the valves under the sink

Step 3. Remove the old mixer by unscrewing the fixing screws
You will find a screw under the decorative cap on top of the faucet.

Step 4. Unscrew the metal clip under the sink

Step 5. Place a new drain in the center of the sink drain
Place the gasket over the tip of the nipple and tighten the nut to secure the pipe in place.

Step 6. Hand tighten the nut

Step 7. Slide the T-piece over the end of the nipple
Connect it to the hot and cold valve and tighten everything in place.
Method 2 of 4: Connecting a hot and cold tap

Step 1. Push the hot and cold valves into the corresponding holes

Step 2. Tighten the nuts on the valves under the sink

Step 3. Attach the flange over the top

Step 4. Attach underwater braided hot and cold faucet hoses

Step 5. Connect the other ends of the hoses to the T-piece

Step 6. Tighten the nuts on all four ends

Step 7. Place the mixer handles on the valves
They should look outward when off and inward when on.

Step 8. Tighten the supply line to the hot and cold tap and to the isolation valve
Method 3 of 4: Installing a Drain Collar

Step 1. Remove the siphon (siphon), pipe, and clamping rim under the sink by loosening the nuts

Step 2. Slip the silicone over the new drain collar and thread it through the hole

Step 3. Screw the clip onto the collar

Step 4. Tighten the nut under the sink

Step 5. Attach the old nipple to the drain clamp and replace the siphon
Method 4 of 4: Attaching an Auto Plug
The automatic stopper consists of a lifting rod that is attached to a metal fixing bar; the ball rod is attached to the bar. The ball is lowered into the drain to control the plug.

Step 1. Place the spacer, nut, and spring clip on the ball bar
The ball bar is attached to the lifting bar and contains a ball at one end.

Step 2. Insert a rod into one of the holes on the metal bar and fasten the spring clip to it

Step 3. Insert the spacer on the other end of the rod and place the ball in the groove

Step 4. Hold the plug in the drain hole and use the rod to catch the clutch

Step 5. Tighten the nut on the drain tube, but not too tightly to allow the ball to move

Step 6. Insert the lifting rod into the hole and into the metal bar

Step 7. Supply water to the tap
Advice
- Remove the aerator to purge the system before use.
