I have a Pentair Meteor sand filter that I suspect has never been deep cleaned. I've been through the tutorial here and the owners manual so I think I understand how to open the unit and get the process. However, I want to make sure I understand how to disconnect and reconnect the plumbing from the pool. Here is a picture:
From the looks of it the two "collars" on the white pipes just need to be unscrewed so I can remove the filter top. Is that correct? If so, when I reattach them will I need any type of thread sealant or adhesive? This is new to me and I want to make sure I have any needed materials on hand before I start. Thanks in advance for any help.
