I want to thank everyone for your very helpful suggestions. Yesterday's kids' pool party went rather well. Here are the pictures:kids' faces have been edited out for privacy.
Kids loved the slide, even though it may look ridiculous for adults. They spent a couple of hours playing in water. It was about 95 degrees, and the water was about as warm as well due to constant recirculation.
One thing I will do is add a tee or a cross on the intake side to avoid injuries related to body parts sucked in. That was a big mistake on my part not to do it, although I did cut some notches around the intake opening.
There were no injuries around the pool, but one child bumped into another on the swing, resulting in a blackeye.i
