First - Thank you to the TFP community. You guys are awesome! I am so grateful that I have someone to ask all my questions to! (And I have MANY!)
So here's my latest . ..
The pool is OLD - like 1950's old. The pipes are steel, the sides are steel, the bottom is concrete - everything exposed is painted in epoxy paint.
Each time I shut down the pump (as necessary to clean to filter basket, and backwash, ect . . . ) then when I restart the system, I get a burst of dark brown cloudiness from the return jets. The 'cloud' eventually settles to the bottom of the pool as a very fine 'dust' that is a dark brown / copper color - not unlike rust. The 'cloud' usually only lasts about a second or two, and the water that follows is crystal clear.
I should note that thanks to the TFP forum I did finally learn the correct method for backwashing - and my procedure for that is: 1. shut down the pump 2.perform backwash 3.run 'filter to waste' / rinse 4. return to 'filter to pool'. I usually run the backwash for at least 2 minutes, and the rinse for about 1 minute. I should mention that I've been doing this for about 2 weeks now - and at no point have I actually seen any dirt or debris come through the clear section of pipe at the backwash outlet.
I realize that due to the age of the pool, and the fact that the pipes are steel that rust is just a park of this gig . . but I find it odd that the burst of dust only lasts a second.
Any thoughts on this matter would be most appreciated!
