Good Morning, this is my very first time attempting a forum like this.. I am in need of advice... The manual to install my dual suction pump is so confusing. My 26x52 intex pool has been a pain from the beginning. I now have it up and almost full, but need advice as to how to attach the rigid tubes to the rubber nipples they have sticking out of it.. If i tighten the hose clamps, it simply collapses on itself, not attaching properly. Am i suppose to feed the larger diameter tube into these rubber things?? HELP! I have an 8 yr old dying to go swimming, and my fiance is a disabled vet in need of water therapy!!
