I have an older Sayco faucet, I have no access panel to it. I replaced the stems and seat on the hot about a year ago. Works great now I have done the same for the cold side. Worked for about 3 months. I replaced the washer and it is doing worse it seems. I know it is probably a really old faucet and should be replaced, but that is more of a job than I want to tackle. Any tricks to get it to hold in there a little longer? Sometimes it will stop dripping for a while, then it will start back up. I am so confused
