b. Aerators: Issues reported / observed this month included: i. 2 of the 3 diffusers are boiling in Lake L-12. ii. I believe there are multiple diffusers that appear to be broken throughout the community. Normally a diffuser disburses the air evenly and you ll see a bubble pattern similar to the one shown below to the left. I m seeing bubble patterns that look more like a small geyser which is an indicator that the diffuser plate has disconnected from the pvc pipe. This concern will be reported to Vertex. Even Disbursement Geyser Disbursement iii. The compressor unit for Lake 17 was found not operating. The cabinet was extremely hot and when I opened the lid I found that the fan wasn t plugged in. The fan was plugged back in and normally once the motor cools down it turns back on. The seal around the door also has to be replaced. This system will be monitored. c. Fountains: No issues observed this month. 3
