I haven't seen this talked about other places and wanted to put this out there for those that especially might need replacements parts. Due to an issues I had with a Waterway Filter I purchased, I was trying to find the replacement part locally and found the same item number at Leslies but under their Jacuzzi line. Sure enough, I pulled up the replacement part guide for a similar Jacuzzi model (https://lesl.a.bigcontent.io/v1/static/Jacuzzi-JCF425-Cart-Filter) and compared to the Waterway filter guide (Crystal Water Cartridge Filter – Waterway Plastics) and all the parts numbers I checked seemed to match or have just a slight variation. Hopefully this can help someone else find replacements parts easier/cheaper with either brand you have.
