I just installed new faucet in one sink and garbage disposal in another. In both cases, the pipes leaked. I tightened the plastic compression rings, made sure there were seals where needed, etc. But still small leaks, especially after the sink that I had filled had emptied. It would look good, then I’d look again after a few minutes and there would be a small puddle on the floor of the sink cabinet. Any ideas of what I am doing wrong. Thanks
