I have a kidney shaped pool (about 10,000 gals) with 14 pop ups and 3 side jets (5 stations). The pop up heads in the shallow side work great but, the one station in the deep end seems to have a design flaw. For one, there are 4 heads in that station causing a large pressure requirement to get the heads to pop up all the way consistently. This particular station has only 1 low flow head (on a shallow step) and 3 high flow heads in the deepest part of the pool. My pump is nearly 20 yrs old (as is the pool) and I'm going to replace it soon. My plan is to buy a higher pressure pump.
1) Will doing this have any adverse affect on the other stations?
2) Will my plumbing be able to handle the higher pressure?
3) Are higher pressure pumps available? Is this a good plan?
4) Are there other options for me besides a robot?
I like the in floor cleaners but I would like them better if I could get them all to work as they are designed.
Additionally, I have air bubbles coming up thru the pop up heads. Is this always indicative of a suction side air leak?
