HOB overflow noise/water level

[jaws7777]

Got everything done except for putting the hose on the drain into the sock. Oddly enough everything worked great no leaks no floads but the i dont understand whats going on in the over flow.

The water level is fluctuating with in the box when it gets too low it starts t9 suck air.
Wven worse when i put the prefilter sponge on the noise is constant.


I screwed up the peice of pvc that came with it so swapped it out with the same diameter tube. Not flexible at that length.

Plumbing from overow to sump is 1.25 inches

No I am sure if you make a stalk man stand pipe you can buy a 1"cap and a 1.5"coupling will fit snug on the cap.

Thx miller

What would cause the level to fluctuate ?

It doesn't have enough water volume in that section to alow the air/water mixture to level itself out. What you could do for the time being is drop a 12"piece of airline tubing down the tube and use a close pin to attach it to the side of the box. It will allow air/water to mix easily

Im gonna try and glue the little plastic peice onto another tube i guess it is needed if that dont work i'll try the airline tubing

What's happening is that the siphon forms when the water level raises, causing it to suck water much more quickly. When the water level lowers and it pulls air the siphon breaks, allowing water to briefly build up until it forms a siphon again.

That helped. Much better now. Slight gurgle everynow and then.

If you make a stand pipe you can make it virtually silent

 

[jaws7777]

With the vid you posted earlier ?


I guess the plastic tupe is needed i glued it back on to another tube gonna let it dry over night
