Bladder surge suppressor

An attachment assembly used for attaching an elastomeric bladder to a container comprising:

• a first attachment member having central opening configured to accept a valve stem of the elastomeric bladder therethrough, wherein the first attachment member body is configured to be disposed within the container and has a bottom-most surface that contacts a portion of the bladder or the valve stem;
• and
• a second attachment member having with a central opening configured to accept a portion of the valve stem extending from the first attachment member therein, wherein the second attachment member has a top surface that is disposed outside of the container, and the second attachment member has a bottom-most surface configured to contact a top-most surface of the first attachment member;
• wherein one or both of the first attachment member central opening and second attachment member central opening includes a surface feature configured to register with a surface feature along an outer surface of the valve stem to fix rotational movement of the bladder relative to one or both of the first attachment member and second attachment member.

A method for rotatably fixing a position of an elastomeric bladder valve stem relative to a container comprising the steps of:

• installing a first attachment member over the valve stem so that the valve stem extends through a central opening of the first attachment member, wherein the first attachment member is disposed in the chamber and a portion of the valve stem extends through an opening of the container;
• and
• installing a second attachment member over a portion of the valve stem projecting from the first attachment member so that a portion of the valve stem is disposed within an opening in the second attachment, wherein the second attachment member comprises a top surface disposed outside of the container opening and a bottom-most surface that contacts an upper surface of the first attachment member;
• wherein during the step of installing one or both of the first attachment member and second attachment member a surface feature of the valve stem engages and registers with a surface feature of the one or both of the first attachment member and second attachment member to rotatably fix the position valve stem relative to one or both of the first attachment member and second attachment member.
