Above is the Delta 622 single handle tub and or shower faucet. This faucet does not have any type of scald guard protection or balance control protection, It would not be legal to install this faucet in a new home with the current safety codes. This is a simple faucet to repair as long as the nut is not stuck. |
This is all you need to repair the Delta 622 Tub and Shower Faucet. I recommend replacing the ball seen on the left side of the image, remember you can click on any image to see a larger image. The red tin is plumbers grease, do not use any other type of grease on any plumbing fixture. next to the grease is a repair kit for the faucet. |

Some kits come with a new ball and some don't. this is what is inside the kit |
First things first, TURN OFF THE MAIN WATER VALVE. then if possible open a faucet at a lower elevation to keep water that may get past the valve from leaking out of this faucet when you are repairing it. Then remove the button. |

As you can see there is a screw behind the button this screw holds the handle on. |
Use a Philips screwdriver to remove the screw, the handle should just pull off. |

This is what it looks like with the handle removed, note that it is not necessary to remove the chrome back plate to repair this faucet. This is a very important part of the repair, test to see how tight the nut is on the faucet. the nut needs to turn counter clockwise, STOP !!! Use minimum pressure to loosen this nut, if it does not feel like it will move with minimum pressure, STOP.
Read the following so it will not happen to you. |
I tested the nut on this faucet and it will not move, I removed the chrome plate so I can show you what will happen if you just get a bigger wrench and put hard pressure on this nut. Please notice the vertical position of the stem slot it is straight up and down. |

|
In this image I am applying more then minimum pressure, notice the position of the stem slot. If you are trying to remove the nut and you see the stem slot moving. STOP !! There is no turning back at this point. |
In this image I am continuing to turn the what you may think is the nut, but is actually the whole body of the faucet. |
 |
 |
|
You may be thinking how can the whole body turn, the pipes in the wall should prevent the body from turning |
The problem is with the poor design of this old faucet, This is not to say that Delta makes a poor faucet, Delta makes great faucets, and has long sence corrected this problem in newer faucets like the one I replaced this one with. |

There is a main brass body that connects to the pipes in the wall, but there are 3 little soft copper tubes that connect from the main body to the part of the body with the ball inside of it. |
This is what will happen if you use too much pressure on the nut, Trust me it does not take allot of pressure to break this part off, and there is no way to repair it, you will have to replace the whole shower valve. |

This is the back of the part that still has the nut attached to it, note the 2 little copper tubes, the third one is still in the main body. remember you can click on any image to see a larger image. |
This is what is left in the wall, notice the third little copper tube, It's no wonder this part will twist off. Now that I have destroyed this faucet I have to replace it, This shower happens to be a one piece fiberglass unit and there is no access from behind the shower valve to replace it. |

I used a Dremel tool with a tile cutting bit to make the hole bigger, but just a little smaller then the chrome plate of the new Delta Monitor tub and shower faucet that I installed in it's place. |
This is the new Delta monitor faucet I installed with in the small hole I made. |

WARNING soldering in a tight place like this is very dangerous, I'm very good at what I do, I keep a fire extinguisher at arms length and a squirt bottle fill of water. Even with these precautions A fire can be started that I would not be able to put out. if an ember dropped to the floor behind the tub or shower unit and ignited wood shavings that are on the floor left by drilling holes, I
would not be able to extinguish the fire. There are other possible potential fire hazards. It is best to have a Licensed Master Plumber replace your faucet for you, Find a local Licensed
Master Plumber In your area

This is the new faucet with the chrome plate installed note how nice it covers the enlarged hole I had to make. |
I know many plumbers who would not even try to replace a faucet with so limited space, and sometimes it is not possible even for me, in this case you can use a goof plate to replace the faucet. |
|
I know what you are thinking, thanks for showing me what not to do, but what about showing us how to repair the faucet if the nut does come off !!!!!
Sorry I could not repair this one so you will have to wait till I find another one that I can repair. Check back with this site soon or you can have me talk you through it by using my Open dialog service |
