i have a few questions about how to blow out pool pipes for winter. I have a 35k gallon vinyl liner pool, solid safety cover, a cartridge filter and live in TN (Mild winters) where temps might get into the 20s for a couple weeks.
in the past, I have not lowered the pool water (Local pool companies advise this because of the mild winters and solid pool cover) and I hook a air compressor to the drain plug hole of the pump. One at a time, I open one the Skimmer valve and wait for air bubbles to come out then I plug it with a gizmo skimmer plug, never shutting off the compressor. Next I do the return lines, wait until air bubbles come out then plug with a rubber plug. Finally I move to the main drain and when air bubbles come out I close the main drain valve to trap air in the line.
this year I have replaced my sand filter with a cartridge filter. So my questions are related to blowing out the line with a sand filter compared to blowing out lines with a cartridge filter.
1. Can I use the same procedure to blow out the lines?
2. do I need to remove the filters before attempting to blow out the lines? To avoid damage to the filters?
3. After blowing out lines and cleaning filters. Is it ok the store the filters in the housing if it might get below freezing?
any other advise would be appreciated!
