Sorry been crazy busy with work and didn't see your message. Do you think I should not have check valves on the loc lines? I know they could fail, however I also plumbed one on my return line, figured it would be better to double just in case of any failure. My fear is the top has two loc line holes one half way down on the tank, would the siphon stop after the upper return gets air? I just finished plumbing and its easy enough to remove the check valves from the top, but removing the one below will cause me to cut my plumbing. I know the adage is to make sure you sump can handle if the return pump fails or electricity goes off, but I was working with a sump that I already had. I have enough room to get a larger one, which I might when I get some more funds, but currently saving for a light and skimmer, as I have my rock and sand/salt so just needed to get this plumbing done and tested.
Here is my plumbing job. I did a manifold as I was thinking for future growth, the only thing I'm going to change is probably cut the t line on the right above the return and use a 90 to push back/down the manifold so I have a little more room for my skimmer top when I get it. I have about 4" to go back and then it would allow me to strap the manifold line to the wall.
What do ya think? I just need to hook up my apex and get some power and water in it, but going to wait a day or so for everything to cure.
