Raypak Protege SF Sand Filter Tank (16 in., tank only)
Best overall — a single-model tank at the lowest price here — A one-piece 16 in. Raypak tank whose rating describes this tank alone: 4.4★ across 51, with only two written critical reviews in five years and 9% of its ratings at one or two stars. At $149.99 it is also the cheapest genuine tank here. The catch is parts and paperwork: its one durability complaint is a valve handle whose replacement did not fit, and Raypak's warranty reserves the right to reject marketplace sellers.
How to read a Showdown Score™
The only score that counts how often a product breaks, not just how owners feel about it.
- Three parts add up to the score: what owners rate it, how often it fails them, and whether a credentialed tester backed it.
- Bands: Exceptional 8.5 and up, Excellent 7.5, Very good 6.5, Good 5.5, Fair 4, Poor below 4. Every score is dated.
- Price, the warranty and what a link pays us stay out of it.

- Only two written critical reviews in five years, and 9% of its ratings at one or two stars
- The cheapest genuine tank on this page at $149.99

Cons
- One owner's valve handle broke at one season, and reports a replacement costs more than the entire filter — and that 'it is NOT a universal fitting. The replacement I bought does not fit'
- Sold by a marketplace seller, STL PRO, Inc.; Raypak's warranty reserves the right to reject unauthorised internet sites and marketplace storefronts, and nothing on the listing says this seller is authorised
- Only two left in stock at our read, on one of the slowest-selling listings here
- 51 ratings is under our own early-data bar
Two cards, and one of them is the most relevant complaint in this whole category: the valve handle broke after a season, the replacement part cost more than the filter, and it did not fit. The other is a leak from the backwash port inside the first week.
