Hi everybody! You guys do a wonderful service in this site.
I would like to ask you some questions. My pool specs is on my signature. (Intex Krystal Clear Sand Filter pump 14" SF15110).
Q1: The pressure gauge on my sand filter goes to yellow when running the filter and drops to green when I turn it off. It used to be on the line between the green and the yellow. Is that normal?
Q2: The reason I said the color is bcause I cannot read the real numbers because of condensation on the pressure gauge. Is that normal?
Q3: When should I backwash? What is the reason for it?
Q4: What is a pressure numbers that I should expect? Does it depend on the pump or there is a standard?
Q5: Do I need to install a rose/clamped on the Drain outlet only when backwashing? Does it have to be covered for filtering? I saw some videos and it seems that you have to remove the hose and cover.
Thanks for your help.
