Hello I am a new pool owner, which is a pool that came with the house we bought.
It has been a challenge trying to learn everything I can about it and just found this site a few days ago.
I have a question about the plumbing, there is a large pipe exiting the filter and then goes straight into the ground to return to the pool.
That pipe has a tee in it with a much small pipe coming off of it, maybe a 1 inch pipe. It also goes into the ground and there is a shut of valve on that pipe.
I attached a photo.
Thanks for all the information on this site.
