| Tom,
Unable to route any lines on the bottom side shaded area due to site constraints.
Standard 4" bottom drain, no diffuser, unfortunately I started buying components for the pond before the Diffuser Drains were readily available.
The picture below hopefully will give you an idea of the slope for the pond. I worked really hard to try and minimize the effects of the single bottom drain compromise.
Skimmer circuit pump is rated at 2700 GPH
Savio Skimmer 2" gravity to pump
head loss with piping as planned should put me in at 30-36 GPM.
Thinking of installing a 3" mid water drain into the the first settlement chamber above the 4" line and plumbing it so I can divert to skimmer line if I find I am over sucking the skimmer.
I will be pushing about 70 GPM on the BD circuit.
Total exchange should be about 5800-6200 GPH on a pond volume 6000 -6400 gallons. (with filters and associated plumbing I should be no more than 7000 total) I was going to use one of the 3 TPRs on the BD circuit to be able to divert from the TT if I need to change media, maintenance etc.

Orange lines show the grade
Blue lines show height
Red lines show width
yellow line will be final fairing in after walls are insulated. |
