When I turn off my hose bibb (hose attached), the hose to bibb connection leaks with a good amount of pressure to spray water all over for about 2 seconds. Is there some sort of residual pressure that builds up in my plumbing after shutoff that forces this back spray? Is this damaging to the other plumbing fixtures in my house? This happens at all four hose bibbs in my house. Thanks for the advice.
