Yea, the last 2 pumps went out at the same time 1 was 7 days old they were gritty as you turned them and the stems broke after a few turns. The water was clean there weren't any floaties looked like regular water, but we have super hard water lots of iron if i would have known i would have had water hauled in, The dealer set a couple of the previous failed pumps in to Taco the failures were casued because of calcium deposits, the softner cartrage from CB is new this year and wasn't available when i did my setup. Conditioned water is Super important especially where the pumps are concerned.
