Most service calls result in customer error rather than faulty parts.
The Boss Simple Inflation Kit is supplied with 2 x Pneumatic manual deflation valves, if these do leak, there is generally 2 reasons:
Dust dirt has blown through the airline and into the valve when exhausted causing the valve O ring not to seat correctly.
To Remedy: – Remove Valve and blow air through the small exhaust hole in the fitting while holding the button in.
The airline has not been pushed into the fitting correctly.
To Remedy: – make sure the airline has gone at least 12-14mm into the fitting and a sharp pull backwards to lock the tube.
It is imperative that airline is flushed clean before connecting to any fittings.
Failure to do this could result in blockage of valves and fittings.
Best practice is to tape ends before routing through vehicle and use compressed air to clean the lines of foreign matter before connection to push fittings.
