Thermosysphin Help - Surging Liquid

[Iamclayman2000]

Hello All.
I am new here and not sure if this is where i need to post this but here goes.

I have a 10 Ton Flooded evap thermosyphin chiller with a hasagawa compressor.

The surge drum is over filling and shutting down the chiller on high level. I shut off the liquid line to the Ha Phillips float valve and tried to pump down the system. The level in the surge drum kept rising and fallling even though the liquid source had been valved off.

Why would the level fluxuate that much when no liquid was entering?

What would cause the level to rise too high? I took apart the float valve assembly and cleaned all the parts then reinstalled it and it seems to help.

I have attatched pics to see the level indicators.
You can actually see DIFFERENT levels in each glass when this problem occurs. There is distinctly levels inside the glass ports. WEIRD

any opinions or help would be greatly appreciatied

I can email better pics if anyone needs.
