Just doesn't work. Had another prior that's been fine, but this one will not for the life of me stay attached. Thought it might be me, then had a handy man friend try, then a plumber friend, then my DAD, who literally built his own house form the ground up (he and my granddad had an HVAC comp. for 55 years, but well-versed in old school everything fix it). Stinks, because way past return date.
