Seeing everything about thru-wall skimmers, I definately want to install one. When I do, i will attach the skimmer, screw it on, and then cut the hole. My main concern (And my dads) is that the liner may tear where the skimmer was put in and totally ruin the pool. Whats your opinion on this? I know that it is well worth the trouble to do it and the skimmers are only $25 on ebay. I'm just so tired of my pump sucking air through the intex one, and i plan to use the old port for a deticated vacuum line The last thing i want is for the liner to tear. I will most likely order a smaller mouthed skimmer as its only a 16 foot ultra frame pool. Once i do, it will all be hard plumbed.
