Question about Delta Model 440: Signature Single Handle Kitchen Faucet - White

1 Answer

My Delta Kitchen Faucet Model 450 leaks. I have a repair kit containing rings, springs,cam and packing. The cam and packing seem too thick to fit the faucet. Will the stem of the ball be able to reach the top part of the faucet? Thanks.

If it is a standard delta faucet, the ball is keyed to a small pin in the socket, the
black rubber packing and plastic insert fit together, and the plastic insert is keyed
to the threaded swivel. The springs and seats sit down in recesses in the socket so
everything fits together. On the top of the cover there is an adjustment for tension
which has 4 slots in it, do not overtighten it and remember to use the red capsule
of plumbers grease supplied to extend the life of the seats. Don't try to use the cheezy
wrench to take the allen screw out, but instead a good allen wrench.
(remember to turn off both shutoffs before disassembly and check first).
If you have trouble removing the cover you can use a broken off hacksaw blade
to carefully saw through it or use a dremel with a cutoff wheel and pry it open. Buy a new
one first to indicate how deep to saw.
Hope this helps.

Delta 400-DST Single Handle Kitchen Faucet Spigot Drips


I've installed quite a few of these from the big box stores that leak. There are 2 rubber pieces inside the valve body that act as seats. The seats are what turn the water on and off as you move the handle. These rubbers need to be replaced. You can buy a delta repair kit, which will contain these parts. Where the faucet is new, it might be easier to bring it back

Tip

Ball-Type Single Lever Faucets


BALL-TYPE SINGLE-LEVER FAUCETS

  • The single-handle faucet with a ball inside to control both hot and cold water may either leak at the spigot or at the handle. A handle leak is usually caused by improper adjusting-ring tension. Simply adjust the tension to stop the leak. Leaks at the handle can also result from a worn cam gasket. Dripping from the spigot is usually caused by worn spring-loaded, soft rubber seat assemblies.

  • Parts for ball-type faucets are available in kits. Get the spring/seats kit for spigot leaks, or the complete kit for handle leaks. It may be advisable to use the complete kit to replace all working parts of the faucet at the same time. In any case, you'll need a kit containing the spanner/hex wrench for removing the handle (hex end) and turning the adjusting ring (spanner end).

  • Without turning the water off, loosen the handle set screw. Slide the handle from its stem.

  • For a handle leak, try using the spanner wrench to tighten the adjusting collar. Tighten it by turning the wrench and collar clockwise until the faucet doesn't leak when it is turned on and off. If the adjustment is too loose, the faucet will leak. If you turn it too tight, the handle will be hard to move. When the adjusting ring cannot be turned with the wrench, it is corroded. At this point, you will need to remove the cap to free the adjusting ring. (See next step.) You must turn the water off before removing the cap! Apply penetrating oil to the threads, remove the ring and clean all parts before reassembling.

  • Install the seats. For faucet leaks at the spigot, you must install new rubber seats and springs. You must turn off the water to make this repair. Unscrew the chrome cap by turning it counterclockwise. If it won't turn easily, wrap electrical tape around the cap and turn it with pliers. The adjusting ring, which is threaded into the cap's center, will come off with it. For a seats/springs replacement, pull the ball up and out by its stem. The gasketed cam will come with it. Now you can locate the two rubber seats and springs inside the faucet body. Remove them with pliers or yours fingers and install the new ones. The springs go into the holes first, and the cupped sides of the seats fit over the springs.

  • Service the ball. If the ball is dirty or coated with scale, clean it or replace it with a new one. Both plastic and brass balls are available, but use a plastic one if your home has hard water.

  • Reassembly. Put the ball and cam back into the faucet with the slot in the side if the ball fitting over the pin in the faucet body. Then make sure the tab on the cam slips down into the notch in the body. Not aligning the tab and notch is the number one cause for a faucet leaking after it is repaired. Finally, screw on the cap and adjust the ring as described in Step 2. If a properly adjusted ball-type faucet leaks at the cap, the cam and gasket must be replaced.

  • Swing spouts. If a single-lever ball faucet leaks at the base, you should replace the O-rings. Remove the spout-retaining parts, as well as the spout. Wrap the spout-retaining nut with electrical tape to protect it, and remove the nut with a wrench or pliers by turning counterclockwise. Remove the spout by pulling it up and side-to-side. One or more O-rings should now be exposed. Take the O-rings to your hardware or home center store to get matching O-rings for replacement. Clean any scale that appears on the spout base, faucet body, and the inside of the swinging spout. Install the new O-rings and reverse the steps above to reassemble the faucet.

HOW DO I INSTALL A SEAL KIT


A metal ball controls the temperature and flow of water from the spout in the vast majority of Delta single-lever faucets. That ball rests on three rubber seals, each seal suspending the ball with a single spring. Over time, wear on the seals, the springs and even the ball itself typically results in leaks. Thankfully, repairing the faucet is relatively simple, and Delta even makes repair kits with the replacement parts needed for each model.


Turn off the valve that controls the main water supply. The valve is located next to the water meter, inside or outside the house, and must be twisted in a clockwise direction.

Remove the plastic cap from the center of the faucet's handle by prying the cap free with the blade of a dull knife or a flat-head screwdriver, then remove the screw in the center of the faucet handle with a Phillips-head screwdriver. Pull the handle off the faucet assembly to remove it

  • Remove the single bonnet nut that surrounds the faucet valve with an adjustable wrench. Grip the bonnet nut at the base, which is ribbed to give the wrench a surface to grasp, and turn in a counterclockwise direction to remove it.

  • Remove the circular, white plastic cam that surrounds the top of the faucet, pulling it off and revealing a rubber seal, which you also remove. Next, pull the metal ball out of the faucet assembly and pry out the ball's supporting rubber seals and their springs with a screwdriver (the springs slide onto the bottom of each seal, so they will come out along with the seals).

  • Slide one replacement spring onto each of the three replacement seals that come with the Delta repair kit for your faucet model, then insert each seal into the assembly. Insert the replacement ball from the repair kit, then cap it by putting the replacement rubber seal over the ball, followed by the plastic cam

  • Place the bonnet nut over the faucet valve, then tighten the nut with an adjustable wrench. Position the handle onto the end of the faucet, then insert a screw into the center of the handle, tighten it with a Phillips-head screwdriver and, finally, press the decorative plastic cap over the screw.

  • Turn on the valve that controls the main water supply by twisting the valve in a counterclockwise direction to complete the repair

    I purchased the Danco 80701 "Repair Kit for Delta, Aquasource, and Glacier Bay Faucets with #70 Ball" so that I can repair a leak in my Delta kitchen faucet. The instructions on the package are...


    Sounds like the old style center-control delta type faucet, rubber washers describe older type but still good. The rubber seats have holes in middle, supply water to the cylinder which diverts water to the spout, and has a seal over top of ball allowing stem for handle.

    Think they are talking about flex-hose type faucet accessory getting clogged, Maybe: lift the flex-hose faucet housing off the center-control faucet body? Water to it runs directly from center-control faucet and if broken seat gets in narrow line could inhibit spray.

    Kitchen faucet spout too has an O-ring under where it connects to the faucet body. Unscrew large nut where meets the faucet body unit (slip-joint pliers), once free of threads, spout should pull straight up, easy or slight tug. I use bent paper clip to remove old one trying to save it in one piece so as to get exact size (that's important) to replace, push on one side then other.

    Leaking bathroom faucet


    These single handle faucets tend to need the internal "O - rings" changed every couple of years. Find your model # and take it to Home Depot or Lowes or some similar store and find the "kit" compatible with your faucet. Some kits have a cartridge, some have springs, O - rings, etc. The kit will have instructions on how to remove tha old one and install the new one.

    I may be able to help you. Some faucets are made with the option to have a base or to mount directly to the counter.The bigger washer might be the one that seals the faucet to the counter The leak out of the top of the faucet is probably caused from the plastic nut with the grooves in the top of it not being tight enough. The repair kit should have came with a tool that has a allen wrench on one end and two prongs on the other.Use the pronged end to tighten the plastic nut ,If the other parts where put in correctly this should cure your problem. If the faucet continues to leak you can get a pamplet that will give you instructions from a rep at the plumbing supply or on line in one of the sights for Delta Faucets.

    Leakes around spout


    You remove the handle after turning the water off the to faucet. Remove the retaining nut which is apart of the trim. The ball assymbly will pull right out and you will find the two little washers and springs below the ball. You can buy a rebuild kit with the new ball if you like but it is not necessary. When you do replace the washers, it might be necessary to tighen the tension ring that is on the retaining nut. Tighten it unit it doesn't leak around the ball stem.
