Ok I'm REALLY liking this plumbing... can you give some idea/diagram what each item is in this pic
Well its been a while but I'll describe the plumbing in a bit more detail:
Overflow Plumbing (Tank -> Sump):
1. Glass-holes 1500 overflow kit. This consists of two 1.5" threaded bulkheads with two threaded to slip 90 degree elbows.
2. Two 1.5" PVC ball valve / union combo fittings, slip to slip.
3. Two 1.5" PVC 45 degree fittings, slip to slip.
4. Two more 1.5" PVC 45 degree fittings, slip to slip.
5. Two 1.5" PVC 90 degree elbow fittings, slip to threaded. I chose threaded here in order to allow all plumbing in the cabinet to be easily removed without touching the plumbing behind the tank.
6. Two 1.5" PVC 90 degree elbow fitting, slip to slip. I did not cement the side connected to the down spout as this will allow me to remove these pieces easily.
Return Plumbing (Sump -> Tank):
1. 3/4" Vinyl tubing connecting the Mag 9.5 to the start of the PVC.
2. One 3/4" 90 degree elbow, slip to slip.
3. One 3/4" PVC tee fitting, with the branch connected to a 3/4" ball value, a 3/4" PVC 90 degree elbow, and a PVC 45 degree fitting for feeding the refugium, all slip to slip.
4. One 3/4" PVC union, slip to slip.
5. One 3/4" tee fitting, splitting the return to the dual returns, slip to slip
6. Two 3/4" 45 degree elbows on each return, slip to slip.
7. One 3/4" ball value / dual union combo fitting for flow control on each return, slip to slip.
8. Three 3/4" 90 degree elbows on each return, first two slip to slip, the last one is threaded for locline attachment.
