Overflow for sump not flowing?.....

Recommended Posts

Hi guys,

Not sure if this belongs here but feel free to let me know if i have to relocate.

I converted a wine barrel into a fish tank some time ago and am trying to fit it with a sump. It is now all plumbed up but it doesn't seem to be flowing.
Now I'm not much of a plumber so please feel free to be honest, no feelings will get hurt here!

I'm thinking that maybe it is because there is air in the line? The overflow does come 'into' the barrel angling slightly down (due to the shape of the barrel), could this be causing an air pocket like a toilet? It does seem to be trickling through to the sump but not with any real flow.

Looking for any advice/brutally honest criticism haha!

 

Thanks guys

Bit hard to dicipher the photos even though you have tried. 

If you suspect an air lock, you can place a Tee piece on outside of barrel instead of an elbow. Open upper side of the Tee needs to be above the barrels water level so might need a short riser length of pipe too. I usually mosquitoe screen the open end in case insects crawl in. 

If possible, have the bottom pipe which goes into sump kept above water level so air can escape. This might create some gurgle noise until any air is able to purge. You could also drill a small hole in the pipe above the sump water line if you wanted the pipe to stay under water for some reason.

Slightly different topic: 

If you want to set the water level inside the barrel more precisely, add an inside elbow rather than the straight side hole. Use appropriate length of PVC pipe in this elbow to set the water level. Or if the water level still  fluctuates periodically, slide a 5cm length of silicon hose appropriate diameter down the inside of this PVC pipe. You can push or pull this hose piece up or down easily to set an exact water level in barrel. This atrangement will surface skim better as well and is less likely to clog up than your side drain. 

It's also a good idea to step up the drain diameter pipe bigger than your entry diameter in case something does get sucked in. Fish for example.

Maybe if your outlet is in "bottom" of sump then yeah probly air locked as theres more water pressure in sump then top of barrell,, 

Outlet in to sump  should b  above water.

I could b wrong too lol

Thanks guys.

The straight end is just to make things clearer. I had an elbow setup on the inside of the tank but removed for illustration of my issue.

I will try the entry into sump above water level. I was hoping to exit at the bottom to make the most of the biological media there but hoping it will work all the same?

If that doesn't work i will try a small hole at the top of the exit elbow in the bulkhead to alleviate the pressure and see if that works.

Appreciate all the help and will keep you posted!
