Do not overtighten any connections. It is best to apply some oil to the rubber seal on the side of the can before twisting. There is already enough oil at your faucet. After reading the reviews I just put two and two together. You get a small loss when you turn on the faucet. Poorly processed threads can also cause problems. Handle with care and do not use force, dingii (plural of "dingus").
