So today I decided that even if my specialty plumbing hasn't come through I can get started on plumbing the tank, fill it with freshwater to check level, and drain it again. You'd think this could be easily accomplished given that I had the whole day to do it but it was a frustrating circuit of Lowe's, Home Depot, Rona's, and Lowe's again just trying to find the basics I needed for the plumbing. Almost made me wish I'd ordered everything from reefsupplies.ca though who knows when the package will come ... it is, at least, shipped as of Thursday.
Here's the fish closet in the basement:
Both the ABS and the floor drain go to the same P-trap under the tile, and the tile in this room can hold a fair bit of water (I haven't actually measured, but definitely at least a 20 gallon spill should drain pretty harmlessly). The flexible tubing at the top of the picture will feed my RO/DI unit, and the pipes are the bottom half of the plumbing from the office down into the basement, which consist of one ABS drain pipe, two 3/4" return lines, three 1.5" drain lines (BeanAnimal style), and one 2" electrical wire conduit so that I can put automation in both the fish room and under the tank in the cabinet.
The top of the plumbing from the basement fish room comes out of a hole in the tile in the office like this:
and from this angle the wire chase is top, then BA drains, then return lines, and finally the ABS drain to sewage.
I started by building out the BeanAnimal drains. Here's what the overflow box looks like from underneath with two bulkheads installed and the third yet to come:
and I want the tubing that's back here to be removable easily from under the cabinet so every one is threaded at the top and has a true union valve at the bottom. Here's two of the three drain top pipes, that'll be completely inaccessible unless removed once the cabinet is built:
As you can see in the second picture, when installed the bottom of the pipes stick below the stand, so that it's possible to reach back and unscrew it from the bulkhead with one hand to remove it, if the valve is removed. With the valves on the emergency drain (rightmost) has to be rotated so that it can be shut off because the stand interferes a bit:
And finally, here's two of the three drains dry fit:
I couldn't complete the third one because I am short one 45 degree 1.5" elbow - I cleaned out Lowe's, and no other big box store had any at all.
So not a ton to show for a day of running around, though I think I have what I need to do my return lines tomorrow, and my plan there is a bit complicated.
I'll have two return pumps, each running one side of the return lines, with valves so that if a pump fails I can have one pump drive both sides, and a cleanout to the drain that I can use to completely empty a section of water for repair and inspection of the check valves, which I will install to try to make failures less of an annoyance. If power and check valves fail, the effect will be to siphon off the top of the tank into the sump, which will most likely trigger overflow into the sewer, so I'm trying to make that scenario vanishingly unlikely (and yet, dry if it occurs). More tomorrow...
