Believe it or not we use it daily. It probably shouldn't be standing as we had not a clue on how to set it up, how to take care of it, etc.
We started with an Intex Easy Set (with the blow up ring) that was 18 feet by 48 inches. I learned by trial and error how to take care of it. We used it alot and the kids loved it. This pool was given to us and wished we could afford to have a "proper" pool.
My son-in-law had a friend that offered us this pool. We went and looked at it. It was set up and held water. We were totally clueless for the most part, except I knew I could take care of it if given a chance. The guy told us we would have to take it down to move it. He didn't have the top rails on it and had bungee cords wrapped around it. He had used it for 2 years this way with a set of fiberglass over wood stairs on the outside that came about half way up on the pool. His kids had to straddle the thing to get in and then lift themselves over by using their upper body strengths to get out. A deck was included but he had gotten pool second hand and he didn't put the deck up.
The friend took the pool down and we transported it home on a car trailer along with the deck. We hauled 7 ton of sand to put under it. I didn't do a google search on how to put one up, nor did we have any help/knowledge about how to install. We laid out the bottom rail/track, installed the sides, decided that the filter and pump should go on the "downside". We decided to order a new liner so it was a few days before we actually started the installation. After unloading the sand by hand and then hauling into the pool area we were tired, hot, and miserable. We got my husband, daughter, myself, my son-in-law and brother to help drape the liner over the sides and used clothes pin to hold it in place. We had gotten new coping so installed it, and then put the metal track on the top. We started filling it -- took three days running my water 24/7 (we have horrible water pressure). After it was filled. I started laying out the top rails and discovered they were all there (all though we were told they weren't and that is why he hadn't fooled with the top rails). I put them on and was only short two of the over caps or what ever the things are called that cover the "seams" in the top rails. We just left them off the long sides and you don't even notice that two are missing.
The pool is setting on a slight slope and the end with the pump and filter is 7 inches deeper than the opposite end. It has been that way since July 2007. We purchased a new filter (Hayward T180 filter) the first summer. I also purchased a regular above ground ladder from craigslist that first summer (we used the Intex ladder a couple of weeks). The next summer we purchased a Hayward 1.5 horsepower pump. I purchased a solar cover the second year (don't use it much as it is too heavy/awkard for me to take off when grandkids come and they are too little to help). I am not using a 2 horsepower pump but plan on changing it out for a smaller pump.
The pool is far from perfect and has many flaws to it. I have learned so much reading here on the forum. It almost makes me cringe when I see how our pool looks, but it gets the job done and we are making some changes as I learn. I appreciate everyone's wisdom and willingness to help those that are trying to learn.
