I just replaced the cartridge in a Moen Extensa faucet. Now the handle flops down by itself, shutting off the flow. I can run it full open, but no flow level less than 100% will stay on. I've seen the suggestions to remove the cartridge and clean the center shaft of excess lubricant. Did that, no improvement.
Has anyone tried replacing the center shaft O rings with new O rings, same ID but slightly larger OD?
Any new suggestions out there for this issue?
