Got the sand filter and plumbing all done over the last 2 days and fired it up tonight.
It leaks at the center connection where the multiport valve attaches to the "sand tank". The plastic ring with the screws/nuts are as tight as they can get and the multiport valve is sitting flat on the tank.
The tank is not 100% level but it is not completely out of line either. And when I say it leaks I mean water just sprays out with great deal of force.
BTW all valves to and from the pool are open and there is good suction out and water flow back into the pool.
Looking at the diagram I found on Hayward's site could it be the O-Ring on the Valve that is causing this leak?
Above Problem fixed
Ok so I got the leak issue resolved. Now I have a new issue.
The pump/water flow pulsates now. It is pulling the water out fine and the and pumping it back in fine at full speed. Then the skimmer box acts like its "out of water" and the water coming back into the pool slows way down, then after a few seconds it picks back up to full speed and we start the routine over again.
Closing the return valve a little bit helps lengthen the "full power" part of the cycle but does not eliminate.
