## How to Stem Out an Under-Kitchen Sink
Stemming out an under-kitchen sink is a relatively simple task that can be completed in a few hours with the right tools and materials. Here’s a step-by-step guide to help you get the job done:
### Tools and Materials
Before you begin, gather the following tools and materials:
– Adjustable wrench
– Plumber’s putty
– Tubing cutter
– PEX tubing (if replacing old tubing)
– SharkBite fittings (if replacing old fittings)
– New faucet (if replacing old faucet)
– Bucket
– Rags
– Flashlight
### Step 1: Turn Off the Water Supply
Locate the water shut-off valves under the sink and turn them clockwise to close them. This will prevent water from flowing into the sink while you work.
### Step 2: Remove the Drain Stopper
If your sink has a drain stopper, remove it by unscrewing the retaining nut or lifting it out.
### Step 3: Disconnect the Faucet
Use the adjustable wrench to loosen the nuts that connect the faucet to the water supply lines. Disconnect the lines and remove the faucet.
### Step 4: Disconnect the Drain Line
Loosen the nuts that connect the drain line to the drain pipe. Disconnect the line and remove it.
### Step 5: Inspect the Drain Pipe
Use the flashlight to inspect the drain pipe for any clogs or damage. If there are any clogs, use a drain snake or auger to clear them. If the pipe is damaged, it may need to be replaced.
### Step 6: Install the New Faucet
Apply a bead of plumber’s putty to the base of the new faucet and insert it into the sink hole. Tighten the mounting nuts to secure the faucet.
### Step 7: Connect the Water Supply Lines
Connect the water supply lines to the faucet and tighten the nuts. Turn on the water supply valves and check for leaks.
### Step 8: Connect the Drain Line
Connect the drain line to the drain pipe and tighten the nuts. Run water into the sink and check for leaks.
### Step 9: Install the Drain Stopper
Reinstall the drain stopper by screwing on the retaining nut or inserting it into the drain.
### Step 10: Clean Up
Use the bucket and rags to clean up any water or debris that has accumulated during the process.
### Additional Tips
– If you are replacing PEX tubing, use SharkBite fittings to make the connections. These fittings do not require any soldering or crimping.
– If you are replacing the faucet, choose a model that is compatible with your sink and has the features you want.
– If you have any difficulty completing any of the steps, consult a qualified plumber.
### Troubleshooting
– If you have a leak after connecting the water supply lines, tighten the nuts further.
– If you have a leak after connecting the drain line, tighten the nuts further or apply more plumber’s putty to the connection.
– If the water flow is weak after connecting the faucet, check the water pressure in your home. It may need to be adjusted.
– If the drain does not drain properly after connecting the drain line, check for clogs in the drain pipe or vent stack.
