Eheim pro 3 2075, this part broke, what does it do? anyone know?

this is my filter part list.
http://www.eheimparts.com/display_product.php?pid=2075

part that is broken is 7428728, the top piece of that assembly.

I believe this is just to prevent back flow in the off state when pump is not running? is this right? anyone know what this part is for? check valve of sorts?

I have it removed and the filter seems to be running fine and without any rattling now like how it used to be before the part broke.

Just want to make sure its not something that is vital, don't want to cause more damage to my filter. But i need it to run as I don't have a backup

It is a float valve that works as a one way valve as you say to prevent the water from backing down the outlet tube. On the 2080 I think there is a priming button that it works in conjunction with, but I don't think the 2075 has one of those. Either way it is not a critical part as none of the lower numbered units even have one.

It does keep the water from running back like a check valve. If you have no problem getting flow started after cleaning, you most likely can go without it.

I actually removed it from both my 2076 and 2075. Seemed like it might cut into the flow a bit.

Yeah it does cut flow. With it out I am getting much better flow and no noisy clicking / rattling noise.
