SLO Design Questions

Los Angeles Will

I've seen some designs that look like they work pretty well on Youtube as well. My only issue is finding a suitable location for one. Things are pretty tight around the system. And there are a few fruit trees that are kept short enough for light to hit the grow beds, but that shade the ground that is south of the system.

All of the fish that I have currently are good in broad temp ranges, but they slow down on the feeding during this time of the year.

How cold does it get in your part of Florida in the winter?

Wife said last night the water was 41 degrees F.

Too funny. :laughing3:

Will, It’s all about velocity, when you step down in size the velocity increases. Enough to push waste through? Not always.
As you know I have 90mm pipework which I use as headers, I then step them down to 40mm, both these are drain pipe and fittings are designed for gravity flow so don’t have the solid traps you are questioning.
All of this pipework is under ground and the AP area is on a slope and when the 40mm pipe arrives at the beds I’ve stepped down to a 25mm pressure pipe tee and the vertical goes to the bed via a 25mm valve and the other goes straight to another valve and is used for flushing the pipework when solids build. Most solids end up on the bed and although when I flush some solids do come out there aren’t as much as I’d expect and this because of how it gets stepped down with the velocity increasing and the head height.
If it is gravity fed to the beds then many will use an unglued elbow on the end of the pipework at the bed and adjust the flow by twisting the elbow or raising or lowering the outlet which is effectively raising or lowering the head of water.
I think that made sense. :think:

Hope this helps,
Merry Xmas.

Rule of thumb for velocities, gravity = 2 feet per second,
pressure = 5 feet per second, V = Q divided by A, i believe its the formula.
This is where the T piece comes into play, it ensures the SLO is full so if you have sized it correctly you have the velocity to remove solids, to act as a syphon break and a overflow incase the SLO gets blocked.
