Blowing Snow

[Reggae Fish]

My 2 return nozzles on my RR are basically blowing snow. It was just happening about twice a minute but now it is just constant!
Roy looked at it last night and just said that maybe over time that will go away. I just was curious if there was any reason for the increase??? I have a mag7 in my sump that is at the bottom. I used to have lower water but I've increased my water level but I did that over a week ago and this just started today. The return tube does not have any kinks and is clean??? I'm confused. It looks terrible. Does/did anyone else have this problem?

Does the height of the adjustable standpipe have anything to do with this?

you dont need to double post everything...... lol

sounds like you have a leak in your plumbing that is blowing air into the tank (is the main pump making a vortex on the top of the water in the sump sucking in air)

It's very calm in his return area. 2 lockline's coming out in the display. I'm thinking something making a mini venturi effect somewhere.

oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

i thought that you meant that it was blowing sand around! HOW DUMB AM I. forget all i said then! :lol:

There doesn't seem to be any vortex. Also, there doesn't appear to have any leaks. It's just a flexible tubing going from mag to bulkhead. I mean the stuff is so cheap, should I just try replacing the tubing? What would the vortex do just for future knowledge... And what problem would create a vortex?

There is 1 hole in the PVC right before the lockline screws on. Although, looking at it, I can't tell if there seems to be any leaking where that screws to the lockline. I can't really pull that pvc pipe up can I? Wouldn't it all drain into the sump with none returning?Would a pic of that help?

that is a anti syphon for the loc line



is the loc line tight maybe if you extended the loc line one piece is loose


please give a pic

If you're sucking in air, it's ALWAYS going to be on the suction side (unless you have some sort of venturi on the return) - leaks on the pressure side would manifest themselves as water spewing from the pipe. Check your suction fittings, etc. and see if anything is loose. If everything checks out ok, then check for a blockage. You may have something restricting the flow which is causing a small vortex in the pump which is liberating air from the water and causing the micro bubbles.

You may also have an undersized suction line which is causing a vacuum in the pump thus making more microbubbles. It may just now be showing itself now because of gunk growing in the line restricting the flow.

[chadfarmer]

that piece is supposed to be like that a hole in it


on the sump where the pump is can you see any microbubble or bubbles next to the input of the pump

 

[Reggae Fish]

Actually, yes...When I looked VERY closely, there are very tiny bubbles rising from around the input. Actually, it seems to be about where the cone fits onto the pump

 

[TWINPEAKS]

Might try putting one of those prefilters on the pump intake that should stop any vortex and break up any micro bubbles also remember its always harder to seal a vacuum (intake side) as opposed to the output(pressure side).

 

[Reggae Fish]

I had one. Same problem

I just flipped the switch on my sump this morning and have microbubbles everywhere in the display.

Do you still have the problem? How did you resolve it?

Do you have many bubbles in your sump going to your return pump area?

 

[mjpelikan]

It didn't look like it, but I didn't have a flash light.

 

[Shooter7]

Sometimes it only takes a couple of bubbles getting to those return pumps and getting chewed up to cause a cloud of microbubbles. It sounds like you have some distance of plumbing to go through as well and I've heard people say to give your plumbing some time to "slime up" and that helps reduce bubbles. Probably just going to take some close up investigating by you to find the source. Sometimes you have to get up real close and look at the return pump area from above and the sides, etc to finally see that it's getting bubbles from somewhere. I'm sure others will have other ideas of what you can look for. good luck
