Review on 🚰 iSpring FT15 Inline Post Carbon Filter Replacement Cartridge - Superior 5th Stage Filtration for Ultra Clean Water (Pack of 1, White) by Jorge Gutierrez

This filter was changed without warning. This is the same filter part number that I have purchased in the past, but the threaded line connection has been replaced with a slip-on connection. Check what type of connector you have on the input side. The filter system I have has a threaded connector with a "TEE". This new filter comes with a single spline connection. You need to buy a 3 way TEE with connectors on all 3 sides. It would be nice if the manufacturer at least warned you that you need an extra piece of piping to install that new filter.
