Hello everyone. I was having a serious problem with my Zodiac Barracuda G3 automatic cleaner and upon inspection I found that the diaphragm inside had a small rip. The cleaner would move, but barely at all and it would just circle around the deep end. I ordered a new one and installed it today, but now I have a new problem. Without that small rip, the automatic cleaner is working too well. It's sucking so hard that the cleaner stays at or close to the water line in the pool, and doesn't want to move around on the bottom. I used the pressure gauge that came with my cleaner, which states the PSI should be at about 3 but it's reading at 5 - 6 with the FlowKeeper valve on the lowest setting!
Here is a picture of my pump/filter station:
As you can see, the water comes from the pool through the pipe on the far left coming out of the ground. From there is goes into the pump basket and to the pump where it is pumped up and into the filter. There are 3 red knobs. The little one on the right is for the aerator, the middle one is for the fountains, and I am not sure what the far left one does. You can turn it from all the way counterclockwise to almost clockwise without any noticeable change to anything, however the last 1 turn or so causes the filter to start groaning and the pressure instantly jumps from 10 PSI to about 25 - 30. :S If I turn the aerator and the fountains on, you can turn that knob all the way and the filter/pump seem fine so I think it has something to do with the returns.
The skimmer has 2 holes in the bottom, one has suction (the one farthest from the pool which is where the G3 is hooked up) and they other has no suction at all.
There is no valve or anything between the skimmer intake and the pump, so how would I go about reducing the suction? The only thing I could think is to add another Flowkeeper valve. Oh and one more thing, I believe it was working fine about a week ago before I backwashed the filter. The pressure in the filter went from about 13 PSI to about 9 PSI.
