If a valve repair requires replacement parts, only
factory supplied components shall be used. Use of
parts from other than the original manufacturer is
not recommended because it will lead to potentially
dangerous operating conditions. If faced with
repairs exceeding the scope of this manual, we
suggest you contact the Farris Factory.
