We have water test! I repeat, we have water test!!!
I filled up the stock tank about half-way, with the help of my daughter, and turned on the pump. At first nothing happened... even waiting a few minutes nothing happened. Not even my pressure relief loop right back to the stock tank. WTH?!? I unplugged it, checked all the pipes and such, and plugged it back in. After a short wait the relief loop started spewing water back into the stock tank! Woot woot! I then opened up the return line side to the display tank. Nothing... I had to turn down the relief loop side. MrsX and DaughterX yelled from upstairs that we had water coming in the tank.
I turned off the pump when the water level got close to the top of my filter on the input and went upstairs to see how things were going. No leaks at all that I can see at this point. Filled the stock tank up some more and repeated the cycle until the tank was full and the overflows started their part. So far so good!
Once the DT was full I plugged in one of the Sicce Powerstreams to see how it worked. Looks good to me, not overpowered as I was fearing. We spent a few minutes watching the little pvc shavings spin around the tank. I think the gyre is going to work well.
To get the pvc shavings out of the system DaughterX and I took a pair of her pantyhose and put them over the drain lines. Hopefully this will catch most of them while the system is tested.
The only real issue I see so far is that one overflow keeps cycling... it fills, runs as expected for a couple seconds, then I get the toilet flushing effect and the level drops about 2 inches. I tried adjusting the height but it doesn't seem to make any difference. The other overflow is staying very consistent and relatively quiet. What can I do to resolve this?? Is it because my drain pipes are 12"+ under water? Should I shorted them? In the stock tank when this "cycle" happens I can hear the gurgle and there is a lot of bubble/agitation at that output into the stock tank.
I ran these initial tests without anything under/insulating the pump on the stand. It seems very quiet to me for what it's doing. Our water softener/radon unit are louder in comparison. After a bit I put some drawer liner stuff (folded over) under it and ran it again, seemed a little quieter but not much. May get even better once I screw it down.
Going to leave things unplugged for a bit and keep checking the pipes/connections for leaks. Will head out to lunch and pick up another barrel and some more sand. When we get home I'll start rinsing the sand and maybe throw the heaters in the RODI that is ready and waiting.
