I've got a 13 year old GE water softener. Yeah, I know you probably all hate them but it has run flawlessly since I repaired the metering turbine 11 years ago. The softening capacity, however, is not what it once was and I'm assuming the resin may have reached the end of its life.
I coincidentally happened across some resin locally at a great price which I snapped up but didn't realise that I was buying fine mesh and this softener has standard mesh out of the factory. Can this fine mesh resin be used in the softener or do I need a new screen and/or gravel bed?
