I've been lurking on these forums for quite some times and learned a wealth of knowledge. Currently, I'm trying to figure out what the labels mean and what positions my valve should be in order for my pool filter to work properly. I'm a recent home buyer that came with a pool and I'm hoping someone on these forums will be able to provide me some insights before contacting a local pool service guy.
I do have a spa that waterfalls into my pool with in-ground filter heads and the pool was built by Shasta.
I've enclosed two pictures below of my valves and pipes.
Any assistance would be greatly appreciated and if you need more pictures to help decipher my system, please let me know!
