Clarify application of straight ball valve 1/4 turn

To Remove Moen Kitchen Faucet.
Regardless of the type of faucet being installed, there are a few basics steps everyone will follow.
First, shut off the water supply to the old faucet using valves typically located under the sink. Then remove those supply lines and the old faucet.
Before installing the new faucet, check the area around the sink and clean up any gunk or old caulk that you couldn't see before, Simons says.

Hello Ronald G Amann,

The supply lines are many and varied...But unless the wall VALVES are the brand new 1/4 turn BALL VALVES
THERE is an opportunity to make the PERFECT UPGRADE.
(lots of choices here too...).

The are PUSH FIT quick coupling... as well as large supplies of braided flex lines... Simplicity is the key to avoiding FUTURE LEAKS...

Do NOT over-tighten any fittings.
Don't UNDERESTIMATE the effectiveness of the new SHARK-BITE couplings

Hope this helps.

you have air in line
1. turn off water under sink
2 turn faucet on full
3. turn on valves under sink water will sputter then run solid
Hope this helps mike

follow this steps and fix it. God bless you

1. Remove the shower head from the pipe.
2. Clean the arm threads and wrap them with plumbers' joint tape.
3. Screw the head back on and hand-tighten it. Remove any excess compound or tape.
4. Test and retighten as needed.

Repair a shower head that leaks at the swivel:

1. Unscrew the shower-head body from the swivel-ball ring.
2. Find the O-ring or a similar seal inside. Replace it and screw the shower head back into place.
3. Turn off the water supply and open the faucet handle to relieve water pressure.
4. Carefully loosen the coupling nuts at the shutoff valves and at the base of the faucet.
5. Carefully remove the supply tubes.
6. Remove the locknuts that hold the faucet to the sink and lift the faucet out.
7. Clean the area where the old faucet sat.
8. As needed, install the new spray hose and supply tubes, if any, through their holes in the sink.
9. Set the rubber gasket that came with the faucet on the sink where it will be mounted. If no gasket is supplied, apply plumber's putty.
10. Set the faucet into position and center it.
11. From under the sink, attach the faucet locknuts to hold it to the sink.
12. Reinstall the supply lines, then turn them on and test the faucet. Turn it on carefully because the line and faucet have air in them.

It says you have a problem with the hot water. First thing to do is to turn the hot water supply valve under the sink off, and then remove the line from the valve to the faucet at the valve. Then put a bucket underneath the valve and turn it on (carefully). If you don't get any flow, then the problem is in the valve or the pipes supplying the faucet. If you get flow there, then the problem is in the supply line or possibly at the faucet.

Open your cubbards under the sink and look for (2) valves/angle stops. then turn them to the right until the water stops running.
If this doesn't work you'll have to find any isolation valves down line or kill the house supply at the No.1 valve At your water meter.

Check to see that the cutoff valves under the sink are fully open. Also be sure that any shipping plugs or caps in the lines were removed prior to installation.

Your control handle is off by 180°. Remove the handle and turn the cartridge 1/2 turn.

1. If by replacing the flexible hose you mean the hose for the pull-out portion - you have more than likely kinked or bent the supply line to the hot (left) side of the faucet.
a) If this supply is braided, then simply shutting of the water supply, removing the braided line and either replacing or attempting to straighten it out will be your best bet.
b) If the supply is copper, you will have to cut the line cleanly and carefully. you will then most likely need a 1/4" or 3/8" compression/quickconnect BY 1/2" IP fitting to complete your repair.
2. Other possibilities include:
a) Failure inside the faucet body which will most likely be warrantied by Grohe if you push them hard enough.
b) A problem at your hot water tank, most likely the outlet side and *perhaps* you hadn't noticed the problem elsewhere.
c) The hot valve failing to reopen fully despite all appearances; applies if you turned off the water under the sink for your repair.

I hope this helps.
Step11Turn off the water supply. You'll find a shut-off valve under your kitchen sink. Once the water is turned off, open up the kitchen faucets to allow the water remaining in the pipes to drain way. Step2Catch the drips by placing a bucket under the hot water supply line, located on the left side of your sink. Even a minimum of water can cause a mess and be potentially damaging. Step3Use a wrench to remove the compression nut that secures the hot water supply line. Let the disconnected section fall into the bucket. Use the wrench to loosen and remove the nut at the other end of the line and remove it as well. Step4Repeat Steps 2 and 3 for the cold water supply line. Step5Replace the cold water supply line. Hand-tighten the nuts on both ends, then use the wrench to tighten the nuts completely. Repeat the process with the hot water supply line. Step6Turn on the water supply and test for leaks
