Review on 🚰 Culligan Premium RFC BBSA Filter for Gallon Capacity by Marcus Munoz

I've been using these filters successfully since 2012 on a subscription basis and I'm saving. There are ten filters in total. However, the last two I received exploded, pouring charcoal down my plumbing and forcing me to clear the valves in all my sinks and toilets, as well as the water inlets on my washing machine and water heater. My water pressure is within acceptable limits. At first I thought I just had a bad filter run, but I noticed the last two were labeled differently. All previous heavy duty cartridges were marked "Culligan RFC-BBSA Level 4 Heavy Duty Replacement Cartridge". New non-working ones are marked "Culligan RFC-BBSA Premium Heavy Duty Sediment Replacement Cartridge". I have contacted Revain support regarding this change but doubt I will continue to buy regardless of the outcome. Too much work to clean up when it fails. bitten twice.
