Pump replacement, super newbie

[Stargate_to_earth]

Bought a house with an above ground pool in disrepair. Got liner installed, filled with water. Went to inspect pump this morning as it had filled overnight. Water leaking out of output of pump. Disconnected flange between pump and filter and tried to unscrew output line (pvc) , line broke off with threads in pump. Decided to try to turn pump on for a second to verify it even worked, faint hum, no water movement. Tried to turn valve on top of sand filter, wouldn't turn.

2 questions:
Old pump is 1.5 hp Hayward and sand filter and in line clorineator (puck holder) Hayward also, do I just need to replace whole kit and kaboodle, if so should I go with a 0.5 hp pump since pool school says it'll be fine (24' round 48" deep around 13.5k gal), should I go with another 1.5 hp,?

Should I replace whole sand filter or can I just get a new valve?

Thanks

I'd remove the multiport and try greasing the spider gasket with a pool lube first and oil the spring underneath. But yes...just it can be replaced. I'd go for a one horse 2 speed pump myself.

How hard is that to do, sounds like Greek to me. I'm an engineer, so I probably could figure it out... It's been sitting with no water for 2 years and is probably used for 6-8 years before that...

I see screw heads......but you can google up instructions for the model # printed on top.

I found a exact replacement on Amazon for 85 bucks, and a cheap pump see photos.

Guy who put liner in said only had a couple years left in pool structure due to rust, so figured a cheap pump would be fine.

That'll get you there... Good job.
