Up one level pond » days 25 and 26

days 25 and 26
Installed the bottom drain cover with air diffuser and started filling the pond with water. I also decided to pour a concrete pad in the pump pit because I was getting fed up with trying to get everything level on dirt. The pump now sits on a 2" concrete block on top of the concrete pad instead of on a 4" concrete block on dirt. I stopped filling overnight because I needed to adjust folds in the liner as the pond filled.

01_BD Bottom drain installed with white and black Sikaflex (ran out of black in the middle). I added some couplings and headless bolts (thank you, mr. hacksaw) on the three bolts because the original bolts were about 1/2 02_BD_diffuser After installation of the air diffuser. I also installed a Greg Bickal pipe boot on the TPR inlet above the bottom drain. 03_pump_pit The pump pit after pouring the concrete pad. I attached the plywood to the 2x2s (made from a 2x4 ripped down the middle) before pouring so I could leave everything in place without having to remove and attach later. 04_pump_pit
