New Danco 3G-3C cartridge is in pieces. Need help with which pieces and positions that they should be assembled. A schematic would be great. JBM

Turn off the water supplying the faucet. Now open the faucet. Remove handle by taking off index button and removing screw. You may need to purchase a handle puller, 10-15 dollars, and a stem wrench set. After removing handle, place appropiate sized wrench on stem and turn counter clockwise. Before installing stem, make sure it is in the open position. You may need to use the handle to turn the new stem. Screw in clockwise.

you have to disassemble your old faucet by using "Wrenches". than reassemble the new one

If the new parts don't resemble the old ones
they shouldn't be used,your wasting your time.

Take the old parts to a quality plumbing store
where the pros go and get the correct help
and parts

Assemble the hardest part first, but don't tighten it up. Connect the other parts, but don't tighten. Go back to your hardest piece and tighten. Then tighten the remainder.

Danco is an after market faucet parts company that recreates parts cheap for hardware supply chains and such. You would be ahead to try and find the brand of faucet you are trying to repair and get OEM parts. They will probably cost a little more, but will hold up a lot better. I hope this helps.

Danco is an aftermarket supplier of plumbing repair parts for almost all major brands. Look for a danco part that looks like the part you need then check the "compatible with" list on the package.

Call a plumbing supply house in your area, they will be able to help you.

Be sure to remove the metal nose piece that covers the lockout bar when assembled. It may be stuck to the other half of the gun. Replace the bar and the spring and put the metal nose piece in its position over the lockout bar. At this point the metal nose piece will be on the opposite side. This will allow you to replace the 2 halves carefully so as not to loose the spring.

Do not modify the handles, just buy the pieces missing. they are available through Danco. Even though i prefer using original parts.
