Simple video on "How to replace a Goyen diaphragm"

A call from Texas this week prompted this blogg.  The man described the sound as a whooshing sound from inside the collector.  It is air bypassing the diaphragm valve.  Two main causes are a torn diaphragm (most common), or foreign particles in the plant air holding the valve seat open.  Diaphragms are very easy to replace.  Older models have a rubber diaphragm, and a spring in the replacement kit.  The new series 4 valve introduces this year by Goyen does not have a spring.  The diaphragm is nicknamed "Shockwave".   It is performing well, and will last more cycles than the spring design diaphragm.
