Okay went through all my questions and via an extended thread from the 'In Ground Pool Closing' thread got some questions answered and came up with more questions! Ahh! Here are my questions:
• When does system get turned off or is it running continuously throughout the whole process?
-Depending on what you have your system valve set to, while dumping water set it to waste, if you are blowing lines set it to circulate. Closed once you are done winterizing. During the season its set to filter.
• Where to buy Polyquat?
-I find it a waste of money to add anything to water on closing. I have had crystal clear water on each opening without adding any chemicals, and never as clear when chemicals were added.
• Do I use waste or close to drain?
-Waste to drain water from the pool.
• What does close option mean on valve?
-Closed means the system is off and water does not flow freely through it.
• If using air compressor to blow out lines, what PSI should compressor be at?
-There is no right way of answering this, all depends on how long your lines are and such, I find that air compressors are a pain to deal with as they keep running out of air, unless maybe you have a real good one or small pool? I just got a Cyclone Vac which is a monster for blowing lines. Main thing is to be able to blow large amounts of air continuously and I have long lines and know that pool places had trouble blowing them in the past. I had no issues at all with the Cyclone.
• What kind of non-hardening joint compound?
-No idea what this is or why you would need it?
• Where to buy pool/rv antifreeze?
-Wallmart
• How do I get antifreeze into return lines?
-All depends on how your lines are designed, I find its nearly impossible to get it into mine without designing some kind of a makeshift funnel so I do not add antifreeze to my lines at all, if they are blown out properly there is no need for it. I Add antifreeze to my skimmers and auto fill valve hole once they are sealed off. Once I poured some into my spa but the water was a disaster in the spa on opening. Not sure if its related to antifreeze though.
