Q: My S310T2 tank ALSO has a crack at the seam...seems like a poly tank should hold up better. Confirm you do not sell the tanks separately?!? The valve works just fine.

Q: I have a S244S filter. I purchased a new lateral assembly last year SX242MA1 but didn't put it in right away. When I took it out this month I realized I had to cut the bottom elbow to get it out and now I had to order a new bottom elbow. So I ordered the SX244CD2FW Bottom Elbow Assembly which looks identical to mine. But what two different companies sent me looks different than what I have and does not fit my lateral assembly. They say it is the "updated" part. But it doesn't fit the lateral assembly that I have. How do I get the bottom elbow that I need?
