Well, progress has been a bit slow waiting for various parts.....changing my mind, etc. However I managed to get my primary pumps plumbed and hopefully ready for action. Please go easy on me..........LOL! I'm NOT a plumber. I designed the tree's a bit tall because I really wanted to limit / eliminate any 90' bends. It will of coarse hit a 90 right at the top where it comes out of the overflow, however otherwise I was able to keep it fairly free. The tree's aren't finished as there will be a small 1/2" ball valve at the T at the base of the tree's when I get them. This was the dry fit...... The pumps are near a high traffic area and with the tree's being so tall, I felt some support / protection was indicated. It's all put together with screws, so it will easily be taken apart if needed. I just feel a bit better about the odds of this working with the added support. The pumps are both sitting on 3 layers of an old yoga mat! LOL! Yes, I am a bit of a nut. Hope it's not too far out there. Just my crazy design. Working on the Skimmer plumbing at the moment and hope to have that finished tomorrow. I am still waiting for some parts for the overflow that should be here wed.......so won't get to fully run the tank until then, however I will fill the sump tomorrow Once I get the skimmer plumbed. Getting excited to finally be finishing some of these things. Also getting nervouse about possible leaks, however it has all gone together very well, so I am cautiously optomistic. More to come!!!
