Add a booster Pump and run over Concrete?

[falken]

Have you looked into a Robotic type of cleaner (dolphin, aquabot, blue diamond, etc)? I had a Polaris 280 with booster that did an okay job, but did not do a great job climbing the walls (just my personal experience, some others have no issue with this).
Also, even with the sand/silt filter it ended up throwing the finer particals into the water, clouding the water until the filter could filter it all out.

I purchased the Blue Pearl (cheaper cousin of the Blue Diamond), while this is only the second day I have used it but has done an excellent job of spring cleanup.

Might want to be an option if you haven't considered it yet, the cost of the booster pump, the cleaner, and installing all of it I assume would be higher or close to the same as a good robotic cleaner.

More to the point of your question though, I installed a PVC pipe for the purpose of filling the pool after it was built. I have a threaded connection where it comes up from the ground, then the pole that runs to the pool. When not in use I just turn it so the pipe that lays over the concreate goes into the grass and turn it back when I want to use it. I painted it green for the purpose of being able to see it so you don't trip over it while it is over the concrete and for it to blend in better when it is in the grass.

I'm not sure if the whole threaded connection would work without leaking under the much higher water pressure going the booster pump line though.
