I was installing a new shower head (Brand: Niagara Earth), and apparently overtightened it, cracking the washer in the process. Unfortunately, it seems to be a specialty type of washer that has an integrated aerator screen, so I can't just buy a new one in Home Depot. What can I do to stop the water from squirting out of the joint? (Teflon tape and pipe compound didn't work; the threads are not tight enough.)
Any ideas?
