Ron starts applying APOC 133 roof sealant around jack. Behind him you can see the Oatey flashing that have been sprayed with the sealant primer - a sticky black coating on both sides.
The Oatey flashing and the area around it is covered in APOC 133, then the roll roofing material is laid over. Each piece is 2'x2'.
The stainless "self-tapping" screws that came with the SunEarth RexRack did not want to penetrate the rails. They're tough rails! So were were forced to predrill the rails first. We broke a total of three bits doing this. Ron remarked that he'd not worked with such recalcitrant rail before.
The back rail is fully installed.
The two 4'x8' panels are up and mounted. The headers on these panels have not been coupled, they're just clamped to the rails. Now it's up to me to sweat two couplers on the middle heaters to attach panel to panel. On the outside headers I need to cap one on the top and one on the bottom. The other two outside headers need 1" to 3/4" reducing fittings installed and elbows to point back to the supply pipes. I need to determine if this system requires pressure relief valve or not given that it's a drainback design.
