Hello all,
Like many others, we are attempting our first pool closing on our own.
2 returns, one skimmer. Picture of pool equipment and plumbing:

Questions:
- can we use our 3.5 hp shop vac to get the job done to blow the lines through the pump without disconnecting the union from the pump?
- if so, how? E.g., do we stick the vacuum hose into the hole in the actual pump tank where the pump basket is currently?
- if not, should we just get a cyclone blower? Or an air compressor?
- is it okay to leave our pump out during the winter?
- anyone have a list of things to get if someone recommends a modified pump lid (and if anyone knows can you just buy these things already pre-made)?
Many thanks.
