Looks like you have an aftermarket CMP valve:

Top Mount - CMP

A 261 or 716.

Unfortunately, their wbsite doesn't give much detail. Might be time to just replace the whole thing with a Pentair as they only appear to sell the entire top half assembly separately.

new to the pool maintenance. has water coming out from waste line, could be the spider gasket need replace, but where to order and how i know if it will fit, i dont know my model #
Since the tank is a Pentair, I would look into replacing with Pentair Tagelus 1-1/2in. Top Mount Multiport Backwash Valve

Thank you for the information, i think i might just hire a pool guy to do it.
