diy overflow

ok so then how do you prime it? oh might primer lol

[banditpowdercoat]

OK, Thats a good method of priming. They are using a vacuum pump to remove all the air, but there is a check valve in the line so no air can flow back into the system there.

BUT, what he had there still will drain down untill the inlet becomes uncovered. It will not restart after that.

Try what I said with getting the siphon going with cap installed on your T. Then after 15 seconds, remove cap.

And I just remembered, If you put another T in where I drew, your going to have to plug both the inlet and the outlet to the sump in order to prime it. Might be just better to do the remove cap method. Priming and making sure there is no air in the line will be difficult

Man this getting difficult lol. I thought this was going to be easy. This just seems to be getting harder and harder by every min. So I don't know what I'm going to do.

It's part of the learning process. The whole concept is hard to grasp when you haven't done it before. By the time you get that working you'll wonder why you didn't figure that out to begin with, which by that time you will never need to make another one ever.

Sit down, relax. It'll be alright. I know my ramblings have probibally confused you more than I may have helped. It is a gift I have LOL.

Lets look at this systematically.

IN the youtube vid, what you had there worked. BUT, it worked to well in the fact that it lowered the bucket level to much. You did have a siphon there. So, how you started it was good.

But, what is needed is someting to slow and lessen the siphon effect when the tank level gets to the T level. That will be the air hole in the cap.

You need to plug the cap to get water to start flowing over the tank portion of the pipe. When you filled the pipe and tried with the cap off, it just drained the sump line and the T up to the cap. Why? because the cap was off and allowing air in, it was not pulling water from the tank, over the top and down

Now, if we cap it, get the water flowing over the top and down, that water in that line, will remain in there if no air is allowd to enter in the upper U. Once water is flowing and you know its spiphoning from tank, uncap the T. This will let air in and release the siphon that Sump line has. You want the water in the sump line to not be under siphon. The only part that needs to be air tight is the over the tank piping.

Uncapping the T should now let the drain slow down when the water level in bucket/tank gets to the level of the T and stop draining. Add more water to bucket, drain should start again.

If the over the tank pipe is sucking air through the joints, the drain will not restart. You need to make sure that section atleast is air tight!

[Steve_the_nucks_fan]

Ya I think that the joints are letting air in but I don't want to glue everything together and the have to change things around and not be able to know whY I mean. And I think I understand what your saying. I think I'm going to take a break from the overflow for a day or so and then try again. Thanks for all the help dude i think it will go along way when my mind is fuctioning again lol.

[banditpowdercoat]

Ya I hear ya. Just glue the over the tank part, up to your present T. Nice thing about PVC is it's real cheap stuff to experiment with so not a great expense. But I think if you glue the overflow part, that will be fine and won't need changing.

[Steve_the_nucks_fan]

Ok so I tried again. This time I glued up to the t pArt lower the t abit and also lowered the intake. I filled up the bucket and also filled the overflow system I got the siphon going and it was working great. Then I pulled off the cap and still had water movment. Then I waited till the water got down to the level of the t and the water slowed. So I then filled the bucket back up and it seemed to still be flowing but at a very slow rate. And I'm not sure why? Lol any ideas? Should that pipe with the cap that come upward off the t be longer? Anyways let me know what you think. Thanks bandit.

You have to draw the air out of the highest point.
