I was wondering if you guys had any advice. I've observed weak flow from my return jets, and dead spots on the more aggresively curved areas of the pool. The following is my pool:
Red circles are my skimmers (alpha / beta) and floor drains.
Green circles are my returns.
Not listed on the diagram is the following:
A. Extra swimout across from Alpha skimmer close to return 1
B. Swimout and main steps each have 2 spinning returns, one on each side
C. Return jets are 3/8" eyeballs in the pool. Steps/swimout have some other return w/ 2 holes that spins, so I don't know what size it is.
This brings my total return count to 10 with 2 skimmers and 2 main drains. Pool is 6' deep at the floor drains, 3' deep at the main steps.
I was supposed to get 6 returns in total; 4 in the pool and one each in the steps and swim-out. I ended up with 10 (don't ask I don't know). The pump is the same HP that they quoted for the 6 returns (2hp) except now I have 4 extra returns to push water through. I've observed that my water velocity is predictably on the weaker side.
In a attempt to rectify the situation, I have gotten screw in plugs and closed off returns 2 and 5. I've pointed the remaining jets to spin the water counter-clockwise with the jets pointed slightly down from straight/level.
I have much greater velocity now coming out of the pool jets and the stairs/swim-out steps. I feel like this is closer to the design that the builder sold me, and the velocity of my jets seems to agree.
What do you guys think? Did I do something stupid, or is this worth the experiment. I have not seen my pressure gauge move at all on my filter since I plugged the 2 center returns. I'm hoping the greater velocity will help move more water than the way I had it w/ weaker velocity yet more returns. Oh, the prevailing wind blows towards the Alpha skimmer.
