More overflow questions!!

[Ali1]

okay, made some progress today. Found a check valve, placed it in the hole on the u tube. I filled the vent up to the highest point, which is at the T since the remaining drips into the sump. I filled the inlet tube. I turned on the pump and began sucking out the air from the check valve, until i got water in my mouth. Siphon seemed to work, but i'm getting this loud gurgling noise coming from the inlet. Some things I've noticed :

1- with the pump turned off and turned back on, the siphon does not continue so the pump continues to drain my sump, eventually overflowing my tank. What does this mean... an airleak around my check valve? If there was an airleak around my checkvalve, wouldn't it be leaking water?

2- I intend on painting the pipes soon because it looks ugly and generic. Fusion seems to be the preffered brand to go with, any other recommendations?

3- the gurling noise is actually much louder than my overflow box i had. The noise comes from the water seaming through the inlet. I can see the whirling vortex it makes while it sucks the water in. I attached a video to show you overflow in operation to show you what i'm talking about.


here are the pics and a video of how water flows into the inlet.

WOW,
Thats LOUD.
I'm a about to make my own overflow as well and now I'm worried about how loud this thing is going to be.
I hope the ball valve works??!?!?

You'll hear some of it with this one, but if you put a ball valve after it you can slow the splash down and it'll help

Where should the ball valve be?

I'm assuming the same line to the sump, so the middle inlet of the Tee. I just dont see why a ball valve is needed if the gurgle is coming from the inlet(pipe inside the tank). I could understand for the people getting the gurgle in the vent pipe, but how will a ball valve by the Tee fix the issue of the INLET GURGLING?

BTW, i fixed the self priming issue. I unplugged the power and plugged it back in after it drained and VIOLA!!! the siphon continues to drain the water. The issue was with my check valve not being seated correctly. whats the benefits in connecting an aqualifter to my check valve ?

thanks for the all the help ive gotten guys

The ball valve will keep the water from splashing through the overflow by keeping the entire thing a bit more full of water. I did it on my 265 and it worked well. Just be careful to not close it too much or the pump will out perform the overflow.

The main benefit of connecting an aqualifter is that you're pretty much guaranteed that all air will be removed at all times....even after a long power outage. I never thought it was necessary, but wait for a few weeks and suck on the tube. You'll have air in the overflow. Even if the seal for the check valve is perfect, chances are the seat in the check valve is not. If you're using a "duck bill" type check valve it will bleed more air than the type that uses a spring IME. However, both will let air in. If you're around enough to suck the air out of it occasionally it's no big deal, but for $12 the aqualifter does it 24x7.

on my overflows i had made(not currently running and no pics sorry) i had a small piece of clear stiff airline tubing before the check valve. it lets you see when the air is mostly gone since water will start coming up. keeps you from (hopefully) getting water in the check valve which will f-up some. also if you make a note of where the water level is you can see when air starts building up, saved me a couple time when first setting up where air was being sucked up from a hob placed to close to the intake

by the way they look nice, once you get them painted you will be set

 

[Ali1]

alright boys, i'll give the ball valve a try. And i insert this at the middle inlet of my T right?

I'll also give the aqualifter a try as well!

you guys are running up my bill!!!!

Is an Aqualifter a closed circuit pump , meaning one of the holes is an in and one an out?
If so, would that mean you would need 1 pump per overflow?

Ali1-Is the hose at the end of your tee just a pool filter hose?

the hose at the T is a pool filter hose. After periodically searching, i've found out that a bigger outlet will help in decreasing the noise as it rapidly sinks to the sump.

airline inside the drilled hole of the cap did not reduce noise

Instead of using the aqualifter, can I use simply ditch the check valve, and use an airline? One end of the airline will be tucked in the hole(where the check valve was loacted) and the other end will be placed in the tank.

1- will it work?

2-Won't it ensure that i have no air in the line?
