I just bought it today at Walmart for my 14X42 pool, and hard piped it into my existing PVC plumbing. It's nice. I put a valve on it, but even with it wide open , it does not overshoot the pool with my Intex 2650 pump. If I slowly turn off the return going back to the pool, then it gains velocity and overshoots the pool. So I have control over it.
Not bad for $14.99. Looks nice at night.
I just added some more pics to my album. It was dark out, but I think they came out ok. You can see where I cut into the return line with a Tee, put a ball valve, made a connection with a no-hub coupling rather than a union, and finally hooked up to the filter with a hand made adaptor using the box adaptor method.
