In Topic: whistle in MK25/S650

the only problem with adding shims is that it raises your intermediate pressure thats ok if your spring is at the low end of the acceptable range but if it is already near the high end then a shim will likely put it over the top,just as often it is caused by harmonic resonance over the end of the piston tube and this is much more difficult to get rid of the scuba pro kits come with several different hp seats and generally a mk 25 will have a + seat i have switched to a t seat in alot of these whistlers and it has solved the problem,you may have to adjust the shimming after switching seats to get the intermediate pressure back into spec but your tech should be able to figure that out no prob.

dont bent your lever. i am a regulator technician and i promise that is not the answer, the problem is that your technician screwed in the orifice to far lowering the lever height ,the orifice needs to be backed out until the lever height is appropriate and then if you have a freeflow the spring tension needs to be adjusted to fix that , many techs just screw in the orifice till it stops leaking and call it good, i would absoloutely take it back and have them adjust it properly,also check the breathing resistance on a magnahelic it should breathe at about 1.5 or so inches of water anything over 2.0 is too much resistance for a primary second stage but 2.0 to 2.5 is okay for a octo.if he cant get it right have him call scuba pro for advice their tech support should be able to guide him through adjustments and what to replace if it is out of spec.
