| Bottom Drain Design
It occurred to me that it may be feasible to use only PVC in the bottom drain as well as in the pipe. I am considering using a 4 x 4 x 4 PVC tee as the primary drain component. One end would be attached to the 4 inch drain pipe. The other end would have reducers to 1 inch to attach to a 1 inch PVC pipe for incoming air. The air would continue into the tee in 1 inch PVC then turn upward via an elbow joint and an additional length of pipe. I am trying to identify an appropriate item to use for the dome. I am thinking of drilling a hole through the center of the dome and inserting the end of the air pipe into it, secured with PVC glue. That way there would be no "legs" on the dome to restrict the water flow into the drain. Some sort of diffuser could be attached to the top end of the air pipe. Any comments?
