Iíve been lurking through the site for a week or so getting good info as I troubleshoot my pool issue, and now Iím looking for some feedback/advice. The problem is an air leak on the suction side of the pump Ė see the bubbles in the salt cell and from the inlet.
Bubbles - Salt Cell and Inlet.jpg
You can see there are not many fittings above ground on the equipment pad, and theyíve all been re-glued, o-rings lubed, etc. Also, at arrow A, if you put your ear to the pipe, you can hear the water sloshing around the 90 degree bend, and that is pretty much as soon as the suction comes above ground.
The pool is full Ė there is no air vortexing into the line. And there are no bubbles seen at the bottom of the skimmer from the main drain line to the suction line. So all this tells me the leak is underground.
The pool doesnít seem to be losing water, so this makes me think the leak is above the water level. However, I donít see how so much air could be making it into the line that is buried. Which makes me think the problem is at the bottom of the skimmer. But if it was, wouldnít I be losing water when the system is not running?
Today I called the local pool leak detection people, and everyone is busy for 10-20 days out. Here in Ottawa, Ontario, our season is so short, I donít really want to wait. So hereís what Iím thinkingÖ
Iíve think Iíve ruled out the leak being near the equipment pad, and I doubt it would be under the patio and be able to pull that much air. So that leads me to the skimmer bottom where there is likely a void and lots of air to pull. Iím thinking Iíll rent a saw and cut a hole about 24Ē x 16Ē between the skimmer and the bricks, dig out to the bottom of the skimmer and see what I find. If the issue is there, then new fittings and itís done. If not, then I forget about the old line, lift the needed bricks, and trench in a new line (easy to say, but should be done in a week or soÖ).

Here some questions I have:
- Is there any value in waiting for leak-detection guy (at $225), or should I just get on with it?
- Is the hole in deck, 24 x 16 large enough?
- The skimmer is a Jacuzzi with the floating weir. From inside the skimmer you can feel a 90 degree turn just as the water exits Ė will that be an elbow that I can unthread? Iíll want to change the direction of the fitting by about 90 degrees
- Have I missed anything here? I also just installed the MaxFlo VS pump -- old one was seized at spring start up.
