Akita Pool

Eddie, as someone who has designed dozens of pools, I would suggest you put in a double main drain. It is code on all " pools ", and for the safety sake alone, for your beautiful dogs. No need in taking a chance of something getting caught in the suction.

I don't understand what that is. The drain is gravity fed. I will have a gate valve at the end of the line that I will open to drain the line. It is not connected to the pump, so there is no suction other then what happens as it drains.

The problem, as I understand it, is that even with just gravity feed, the drain suction is enough to pull/hold someone down to the drain, possibly underwater. Even if not underwater, the suction can cause bad injuries. With two or more drains, there will be a relief effect, so if one gets blocked it won't develop a dangerous level of suction.

The risk, as I picture it, would be sudden failure of the valve on the end of the drain pipe, or accidental opening, or maybe a tree branch falls on it and snaps the pipe. Then the pool suddenly starts draining and there is a dangerous level of suction.

Excellent breakdown, and 100% correct. Give yourself some piece of mind, add the second drain now just to be sure.

Hmmmm, given that logic may be I should get my ***** out of the bath tub B/4 I pull the plug.

Thank you, that makes sense. The pool will only be three feet deep. I guess it wouldn't be too hard to add another drain, but I really don't want to because of the design I plan on doing on the floor with tile. Nobody will be in it when it's drained. I'll think about it some more and do some research before making a final decision.

Eddie,

Great looking dogs and another interesting project.

I am very curious about this method. I am not sure it would work for us. Since we are on the Black Land Prairie soil (black, heavy clay) we get a lot of soil movement. During the summer, I would work about the soil contracting from the side of the pool and there be a blow/crack (a possible problem as well with a tradition gunite pool) . Will you be filling the blocks with concrete?

Ustmd,
Great to hear from you again. My daughter bought insurance for busted pipes for her Manor house. Twice the pipe feeding water to her house broke because of ground movement.

Eddie, that pic of you on the ditch witch shows what looks like sandy red soil... I guess it is more clayish?

Will you put down some sand underneath it?

Eddie - Curious what brand of food you feed your dogs?

Yes, it's all red clay. It's very stable, holds water for ponds and once you break through the crust, there is always moisture just a foot or so down. There is very little movement in it, so I'm not planning on adding any sand.
