Pro tip: tried fixing my leaky faucet with a $3 washer kit and now I have a bigger leak
Tried swapping the washer in my kitchen faucet last Saturday with a $3 kit from the hardware store instead of calling a plumber for $150, and it worked for about two days before the whole thing started dripping worse than before. Turns out I overtightened the packing nut and cracked the stem, so now I'm looking at a $40 cartridge replacement instead of the cheap fix I thought I was getting. Has anyone else made a small problem worse trying to save a buck, and how do you know when to just call someone?
