I have an older pool that I just got replastered. I want to swap out the old return jets because they are discolored or stuck and were never aimed in any intentional way. My pool is basically oval and it only has three jets on one side of the pool. Is there a preferred type of jet? I see great reviews on Amazon for infusion venturi jets, but I am worried about stressing my old return line with too much pressure. If it matters, I am using a 1HP pump located about 100 feet from the pool jets. on 1.5" return line.
