So I have a multiport valve for a hayward sand filter which I pictured below. My question is, is it compatible, and even if it is, do I need it? Everything I've been reading on how my filter works, makes it seem option. I put a link to a picture of my filter below. I recently bought a 50 year old home and the sand filter here, hayward s200 is extremely old, so I decided to change it out.
Now I'm just not sure if I should the multiport valve or get rid of it.
