Are you referring to the two valves on the back of the head? Regardless, no, I haven't tested. All ears for any test procedures. Will google in the meantime.

Thanks.
KJ,
ISTA has a test plan for the System. It helps isolate faulty valves and evaluates the pump. Do that before going through the work of removing the valves or throwing more parts at it.

There are also scenarios which result in clogged injection ports in the head. Removing the subframe and header is required to assess that last component in the system. Check everything upstream first.

Or just bring it to us and we'll sort it for you.
