I have Pentair Big Blue filter housings. Mine use 4.5 x 20 cartridges, that are very available in many types. They don't have a built in bypass. I see now that Pentair has the Big White filters, which do have the bypass.

I see a 244994 BWB-UB-KIT Bracket listed. It is not the same mounting system that hangs the Big Blue housings from four 5/16 x 1 inch lag bolts from above. It may be the pipes that will carry the weight, but I don't know.
I presume the 20 inch and 10 inch use the same upper part, but use a different sump. I wonder if the sumps are compatible with Big Blue sumps.
