Pool Purchase Questions

Hello All. My husband and I are looking at to different places to purchase an inground swimming pool. We are looking at the 3' Radius True Ell size 16' x 42' x 24'. The two places are only a couple hundred dollars off in price. The main differences are the first place recommends a Fusion 25 Nature 2 Sanitizer unit with no main bottom drain. They also offer a 28 mil liner with double polyethylene flexible pipes. The second place recommends a salt system with a double bottom drain. They use a 20 mil liner with schedule 40 pvc pipe. I have went back and forth between the two companies but of course the both say they are the best and why they are the best. I really don't know what to believe at this point. Besides my house, this is the biggest purchase we will make and I really don't want to make the wrong decision. Can someone please help and offer advice? We are located in Central, Pennsylvania if that helps. Thanks again!

a main drain is good to have, two are required to prevent entrapment. I would not use flexible pipe underground, schedule 40 PVC is standard. The claims of most mineral systems vary from misleading to outright lies. I wouldn't have a Nature 2 system and would cut it out if I did. Many people here love their Salt Water Chlorine Geretors. I'd prefer a thicker liner to thinner - can company 2 move on that?

I'd also look for two skimmers and several returns. Pipes should be larger where the flows are joined.

What pump / filter? Heater? Lights?

Flex pipes of all pipes have a much higher failure rate than S40 PVC, though heavy black polyethylene is better than flex PVC.
