Some water going to backwash while push pull valve should be closed

Hi everyone, just realized that my sand filter seems to be leaking into the backwash while it's filtering. I have a push pull valve, and found a few videos on youtube suggesting the o-rings might need to be replaced.

Is this probably the issue, from those with experience? I don't know the brand filter (inherited when we got the house), but if I get the new 2 o-rings and some lubricant I should be able to just pop new ones on and it'll fix the issue? Doesn't seem like the valves are that much more complicated, and I'd rather not call a pool guy unless it's something serious. If I can fix it for 20 bucks vs. 100 or whatever most pool guys charge at a minimum I'd be happy.

Thanks!

I found this on Amazon, seems to be what I'd want:

https://www.amazon.com/Hayward-Filter-Slide-SP410X-Rebuild/dp/B007OJTHPE/ref=pd_sbs_86_1?_encoding=UTF8&pd_rd_i=B007OJTHPE&pd_rd_r=MEEED1CKRX4DVANQJBFV&pd_rd_w=QVl7S&pd_rd_wg=wwrMW&psc=1&refRID=MEEED1CKRX4DVANQJBFV


Not thinking I'd need to replace the actual valve assembly, right? It does appear to be Hayward as well though, these pics seem to be like what I have.

SPX0410BA - Hayward - HANDLE AND PISTON ASSEMBLY is this your piston assembly? There are two piston O rings one larger than the other so you should easily see where they go
I really think so, it looks exactly like that and I can't imagine there are a lot of different models. My filter and everything has no labels on it (the paper label has long since faded) and I inherited this pool when we bought the house. I'll take another look at the rings when it's not dark out and i can fully remove the assembly. I was thinking of seeing if the pool places nearby have them, or just order on amazon, not sure.
