My overflow bow thinks it a toilet

My overflow box thinks it a toilet

Every couple of minutes my overflow has a surge. It empty's down then fills back up again. Every time it does this I get a bunch of micro bubble in my water column. I'm trying to up load a short video. But with no success MP4. Think it's some kind of air issue. Not sure tho.

You either need to decrease how fast the overflow is draining or increase your return pump.

 

[roc5288]

I'll give it a try.

 

[wonderballz]

there should be a sweet spot where the amount coming into the tank equals the amount coming out. I am using the ball valve on my return piping to decrease the flow a touch to equal the drain.

 

[roc5288]

It seems to be working better. But the micro bubble are unreal.

 

[wonderballz]

Is the return section of you're sump deep enough? When my water level is low, I get microbubbles.

 

[DrHarryLopez]

sounds like too much circulation or maybe something a dorso stand pipe could fix

I have the durso Installed I don't think it's that but who knows. I have a sump made by custom king 8" baffles. I'm thinking i might need a sponge in sump

How does this look.

 

[THEDLO]

the air hole is probably clogged

 

[roc5288]

No.. I checked it's open.

 

[THEDLO]

lol i mean put somthing in the hole to remove possible salt creep. my gets clogged every couple months.

get a long piece of airline and stick it down the elbow following the water path to the t, then keep the other end above the water line, that should solve your problem, whats happening is that there is not enough air in the durso.

I agree, the air hole is probably too small. You can also drill a bigger hole into the durso cap. When the hole is too small, it can't get enough air in there to break the siphon which is where the toilet flushing sound comes from.

You mean stick air line in the elbow that's in the overflow ?
Thanks ming i'll give that a try also.

 

[rkaragozler]

yep, start at the elbow that is facing down in the overflow box.

Start with the tubing idea. If that fixes it you can drill the hole on your durso out larger. Go one drill bit at a time, until you're happy.

[rkaragozler]

+1 drilling one size at a time, I made the mistake and went large, had to replace both durso

 

[silentworldj7]

you need to take that cap off of the top of the tee, extent the pipe about a foot above the tank, then put the cap back on but before drill about 7 holes in the cap and put 7 small pieces of ro tubing inside the holes about 2 inches above the cap. in the future you should always use a bigger drain!
the other thing is you have a tru union ball valves under the pre box, the internal diameter of that tru union ball valve is smaller than one inch! I will be at the mahattan frag swap, I am a rep for Two little fish and and installation expert. please stop by my booth and will explain a little clearer. thanks jay
