Check Valve:

The Mazzei venturi injector is supplied with an integrated check valve.  However, in our ozone applications we remove this check valve and replace with a stainless steel check valve The standard check valve supplied with a mazzei venturi is a Kynar material that does not always create a leek proof connection.  The standard Mazzei check valve will also leak water slowly past the seal in many situations.  By removing the stock check valve and threading this check valve directly on the Mazzei venturi a more secure connection is possible with stainless fittings, and a positive check valve with a positive seal is used.
