Hydraulic ram problem that does not work anymore

[mickgras]

Hello,

I have been reading you for some time and I would like to ask for information on a belier.
I realized mine and everything was fine.
But since 2 or 3 days, it does not work anymore.
I would like to know if between the water intake and the impulse valve there must be a breather ie an air intake or if between the intake dc below the water level and the belier it must to be perfectly tight and therefore without air that rushes.
This so that under this shutter there is a little air for the depression to be done.

can you help me?
Thank you in advance.

The breather is only necessary if you have water that is in direct contact with the air in the compressed air bell. I do not think it's the explanation you give.

The absence of breather does not prevent a ram from working but it prevents to last (compressed air that wends as in the water).

So 1ere question: how did you realize your ram? If you have pictures it's even better ...
