My new FX STP stopped pulling water over the past couple days. I replaced the tubing, but no joy. Any help please? Could the roller head be needing of replacement? Not clear how to know when the roller head goes bad...looking like it's working, but no water going thru the unit. Its 3 months old.and have been using 24/7 at 40ml per min since I got it. (using for calcium reactor)
