I've been messing with this leaky faucet for longer than I care to admit. A few months ago we had two separate faucets start dripping from the spout. The are both delta two handle faucets. One is in the hall bath and the other is my wife's side of the bathroom, so both get a decent amount of use. They were installed when we built the house 13 years ago.
My first assumption was that they needed new springs and bushings, so I replaced those. No luck with either one. I then figured, f it, might as well try the cartridge too. My wife's hot water started leaking too, so I did the same with that one. That side I was able to fix. After googling the problem, I found that if the new seats and springs didnt fix it, it may be that the body itself is worn. I checked this in the hall bath, didn't see any noticable wear, but when I put it back together, it quit leaking and now hasnt leaked in months. So....that led me to think I did something wrong when I replaced the stuff in my wife's cold water side. I've tried new seats and springs a couple of times now. I did have it stop leaking once for a few days only to start dripping again.
The fact that I was able to get the hall bath fixed after a few times of re-installing the seats and springs, and the fact my wife's hot water side was fixed, I keep thinking I just dont have something right. Obviously, there isnt much to replacing the seats and springs other than making sure they get seated properly. What i haven't been able to figure out is if the orientation of the body and the handle matters. Meaning, can those get misaligned to where the little holes dont get sealed properly? Or is there something else I am missing? I can understand things not lasting like they used to but these were'nt cheap faucets and the fact that I finally got the other two to stop leaking has me confused.
Thanks in advance
