is to believe everything you just experienced...
(Perhaps an UNSEEN flaw in the "MONOBLOCK")

Buy the replacement faucet... shop around:

They are bad about leaking,you prob. need to replace the cartridge with new one. the seals in them get dry and shrink of they have been sitting in the box for a long time on the shelf or in a warehouse. you never know how long ago they were built and just sitting.

there is never a fiction ring at the washer end, sometimes there is a cup shaped part that holds the washer but nothing else so it must be intended to go around the stem

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.

Hello. These faucets use a replaceable cartridge valve and when they drip they're ready for replacement. Remove the handle by loosening a small screw ,usually with an allen wrench, and maybe another nut under it.The cartridge should pull out but mat be stubborn. Take the valve with you when you go shopping there are many variations.

Thae stem you got that said hot/cold were designed to fit old style cross handle faucets. So both hot and cold turned the same way. If the cold side you are replacing turns the opposite direction then you will need to get a cold stem. Danco does make them. Ask the retailer where you purchased the H/C stem. I hope this helps..

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

first turn the water off,then pull the handle off unscrew the top plastic piece pull neck off replace 0-rings,or cartridge what ever is needed.

They do not all leak. The problem may be that your faucet is simply wearing out and is due to be replaced in total. Try putting some plumbers grease on the cartridge and the chamber.....not too much..........that may do the trick for u.
