The timer went out my my water softener and its not made any more. Will just about any flush valve with timer fit on my existing resin bottle? Rather then buy a whole new system for $700 or so (iv seen and home depot the GE versions for this), I thought I might be able to replace the time on my existing resin bottle.....or even by a new resin bottle with timer/valve already attached. I already have the salt bin and of course its all plumbed. Also, does the resin wear out. Does it have to be replaced anyway? In which case I would go the bottle and valve assembly in one to replace. any thoughts are appreciated. thank you rk
