really nice!!! please post pictures once its done!!
Well, this is the best I could get, it has changed a bit from the rough in to today (like I said, about two years).
Here you can kind of see how the above picture fits into things. This is the best I could get of the whole sump. It is a 55 gallon, so it is pretty small. There are no bubble traps, only two baffles. Thus there are three compartments, the first being the primary intake, which includes the the full siphon overflow, the durso overflow and a line from my water change tub. Skimmer aside, you can also see the mount for my ATO, and if you look very closely, you can see the submerged pump for my phosban reactor. The middle compartment is the fuge, which you can see the light over. And the third compartment being the return compartment.
Normally, you would put your ATO sensor/float/whatever in the third compartment, with the pump. However, I keep the water lever just above the baffles (and there is still enough room for the water in the pipes if the pumps are shut off). I would like to swap the ATO with the phosban reactor; but there is no rush as everything is working just fine as it is...
As you can see here, I also added a union ball valve to the siphon and durso overflow lines.
You can see the dry/emergency overflow here with the white 90 degree elbow going into the fuge compartment now. This was in the first compartment until early spring, when I decided I wanted a bit more room in the first compartment.
The union valves are very useful for maintenance of the pumps; otherwise the pumps would be impossible to remove from the sump. Another plumbing related note... In my very first picture in this thread, you can see a T sticking out about a foot above the union on pump line 1. This is for water changes. This is an extremely handy addition... With that line and the pump in my mixing tub, I can do a water change in under 10 minutes.
Lastly, the original plan was to have the pipes nice and flush against the wall, which you can clearly see they are not. Although the do come down fairly straight through the floor; it was too difficult to get the measurements perfect and keep the weight off the bulkheads on the tank. A second set of hands would have been useful (I could not find the fancy clamps I wanted either), but I was probably doing this late at night, lol...
