Most of this weekend went to working on the yard, lots of stuff I've been neglecting before summer and it gets too hot to go outside...
Today though was mostly about gluing pipe.
Amazing how stiff 1.5" PVC is. Two of these pieces had to be redone, as once they were glued they were 1/4" off. No way to just fudge it though, and just make it work, as it would put too much pressure on the overflow and sump, so I had to redo them. Short one piece now, will have to wait a week to finish that.
Started on return, with backflow prevention on each side, and a bracket to hold the UV tube. I will also have to make a support to hold the weight of it as well, as that bracket can't hold the weight of the UV tube and all the pipes full of water, but it will hold it in place as least.
Quite a complicated piece with UV and bypass on each return pump, plus a flow sensor for each direction to measure flow through the UV, and flow around it. The sum of those is the total flow for that pump. Valves are to adjust flow, and to turn off both the top and bottom to remove the UV tube while still running that return.
In order to fit it all behind the tank, I had to glue everything close together. That's a pain if I have to adjust anything, but at least there are a crazy number of unions, so lots of parts to adjust and remove. And I suppose lots of sources for leaks...
This is for the right side (viewed from the front), the matching one for the left side is next, it will be nearly the same, but slightly different as it will also have a manifold for a chiller, and I'll have to route the return from the pump over to the other side of the tank, over the skimmer, and through the drain pipes.
