Before and after I changed the filter, the water coming out of the door has small debris similar to dust particles in it...Any idea why?
Answer Hello John. There shouldn't be any dust in the lines. Try rinsing the glass before putting water into it and see if it is from the glass.
tubes on new water tank are smooth, old tubes had a notch for tight fitting what do I need to make sure I have a tight fit
Answer Kken, The "notch" in the old tubing, is where the compression ring inside the coupling applied pressure to the tube when installed at the factory. The new tubing will do the same thing after a while. For a good tight water proof fit, install the tube as far as possible into the fitting, then slide the coupler down onto the threaded fitting and tighten by hand as tight as possible. Using a small crescent wrench or pair of pliers, and 1/2 to 3/4 of a turn using the tool, this should exert enough pressure on the internal feral to seal the tube. Do Not over tighten the coupler fitting, it will also cause the fit to leak.
