I recently moved into a home with a nice 22,000 gal pool with a Jacuzzi sand filter.
Question 1 - Where is the model number located on the sand filter? I have looked everywhere but many of the tags are worn or have fallen off.
Question 2 - What is the inspection plug used for? If my sand is low, can I add sand through the inspection plug instead of taking off the top unit?
Thanks in advance for any help provided.
