I have been reading tons of posts and since my pool is on season 3 and getting ready to switch over to an SWG, I am going to make our "opening" process include a very thorough check for any rust...I have not seen any signs of it, but then I haven't really looked for it either...I know that when we put it up last year (we took it down the first winter and left it up this winter), I don't recall seeing any rust and I am sure my hubby/handyman would have spoken up if he had seen any...so, hoping for the best and hoping I can get my sand filter running, my pool vacuumed properly and my swg set up and ready to operate over the weekend! we hooked up the intex vacuum I got and it is not doing a thing...I assume my current pump that came with the pool is not able to operate it, so hoping like crazy that the new pump fixes that issue! also noticed a lot of water escaping at one of the couplings, so will try to address that also and maybe that is enough to fix the problem...overall, lots of work to get done and ready for a new year with new things to learn!
