My original Salvo valve was factory installed by Whites several years ago. (Long story.) The cut a hole in both the inner suit and the tech skin, putting the outer washer over the skin. I did the same thing when I replaced the tech skin with a bullet skin. I had a number of leaks there over the years, most recently while in Florida in February, and I took it to an official repair person there. In his opinion, Whites had cut the hole too big, so if there was any movement of the hole while tugging on the pants legs to put it on, it was going to leak. He was also surprised that the outer washer went over the skin--he thought that would make a bad seal. He had not done many pee valves because they are not used much there, so he called Whites for advice. He was told the outer washer did indeed go over the skin. He therefore sealed up the original hole that Whites had made and created a new one about an inch a way. The new one is smaller than the one Whites put in, and so far it has not leaked.
