IF the solenoid is faulty you would hear it clicking on and off ...... I'd bet it's the needle valve

Thanks guys.
The solenoid is not clicking so it then must be the needle valve but if I open the neddle valve completely then I still don't get any bubbles for a bit and then a whole whack of streaming bubbles. Fencer, I soaked the needle valve and not the gauges themselves. I've had this unit (Milwaukee) for 3 years, bought used for $120.00. Mr. Wilson Thanks for the info but it will probably be cheaper buying a new/used unit than getting it professionally fixed (?)

The seat and disc can get worn fairly easy in a needle valve, especially if the alot of pressure is put on them. (eg- the valve is closed very tightly) Normally a needle valve has very fine throttling, as soon as the seat gets worn that ability is gone. HTH,
Bob

You could add a needle valve after the gauges it will probably give you finer control anyway.
This Red Sea needle valve is working great for me.
