I know this isn't necessarily helpful for your issue but...have you considered using the lemon law for this? If PW is aware of just how MANY leaks you have and hasn't done anything other than offer a little support, well... Let's just say that PW was high on our list but maybe not anymore. I would rather have heard that they bent over backwards, offered you a replacement unit, etc., than that you are essentially left hanging trying to get this all fixed by yourself, even though these issues have existed since you took delivery of it.
