The Gates 2 Year Renewable Warranty Service and Housing Overhaul is a must for all Gates owners looking for care for their camera and housing. The housing overhaul involves changing out all o-rings for the control points as well as the main housing and port o-rings. The housing will be pressure tested and certified by Gates to be at the quality level that one would expect from a Gates housing. Having this done will renew the original 2-year warranty. This service can be done at any time, even if the original 2-year warranty has already expired.
