Review on Kissler PB4993 Delta Style Springs by Ben Rodriguez

Installation was easy and new springs and seats stopped the slow leakage. Two and a half months later the leak is back, not dripping but a steady stream. I examined the "new" seals and found one torn. I was able to keep the old seats and replace the broken part and the leak stopped. None of the old seats were cracked, there are no roughness and notches on the ball. My only conclusion is that the new seal was already defective and using the tool widened the gap until the seal surface was compromised and the leak reappeared. The other seal has worked flawlessly so far. Kinda freaked out.
