I would replace both as they are a single unit.
The bubble counter/check valve combo that is supplied with the regulator will be fine as long as you minimize opening and closing it and reattaching tubing. The plastic nipples are its weak points. Not sure if they are from the start or constant contact with
CO2 causes them to be that way. The water will need to be refilled because of evaporation. After a year of use I noticed a slight leak in the bubble counter (audible hissing). While trying to retighten it I snapped off the lower plastic nipple.
I replaced both with a brass check valve (Rhinox) and bubble counter (Fluval). Would have ordered brass for the latter but had the Fluval on hand. Even though it is plastic it is quite sturdily built and the plastic nipples have collars (the kind that screw on like a compression fitting).
