Because the GXWH70M holds a bigger cartridge, it goes longer between changes, which in practice means owners forget it for longer. A gradual, whole-house drop in flow over months is the classic sign.
Isolate, relieve the pressure, change the cartridge, then run a tap slowly to purge air. Spluttering for a minute or two after a change is normal. Cracked housings or leaking fittings need a plumber rather than more tightening, because over-tightening is what cracks these caps.
