I guess I have been lucky so far. I never turn the water off when switching. But then I never use city water pressure. I just fill my freshwater tank and run my pump. That way I can tell if there's a leak anywhere. I can hear my pump running. If it gives a little burp now and then, there's a leak somewhere.
