I'm not sure how to figure out the flow rate of the in floor system. It has about 8 pop up nozzles but only one at a time is ever active (it cycles among them constantly). The nozzles have an opening of around half an inch and shoot pretty forcefully. This is the site for it:

Unfortunately, the current pump is unreadable (pretty rusted) so I can't tell you the model. The PSI is very high (so high that the last time I mentioned it here people said it was impossible) so I hesitate to mention it.

The piping is at least three inches on all pipes, maybe even four. The pad is about fifteen feet from the spa/pool, and it has runs for the pool and the solar (straight up on the roof) as well as returns.

I realize so much of this is so vague it won't help you help me, but perhaps you can at least answer me this. The pool guy said that if for any reason the pump is underpowered he'll make it good but how can I tell this myself? If the in floor cleaning valves don't pop up is that what I'm looking for?
