Bonding Agent Question (sump)

The amount of force that will try to lift the container
will be equall to the volume of air in container that is
equivilant to the difference in water level. So if your
container is completely empty, and the water around it is
all the wat to the top of the container, then the upward
force will be the same as the downward force that the
container would have sitting on the floor full of water.
That's a lot of force to try to keep down.

Also the way those containers are designed if flexable,
they hold an outward force better than an inward
(crushing) force. However if your inside containger is
verry rigid and round like a 5 gallon bucket, then it will
better handel that crushing force. You might also consider
puting the inside container against the side of the sump,
and drilling some holes throught. Hold it together with
plastic bolts, and use some silicone around the perimiter
of the hole to act as a rubber seal.

Or how about putting a bulkhead in the side of the sump,
and using pvc pipe.

Been a long time since I've been on the newsgroup (my program trashed my
history, and I never fixed it until now).
I have a large 150 gallon rubbermaid-esque sump that I am placing a
large polyethylene container inside of. I need to find a way to get the
container to stick to the bottom when water is in it (this is acting as an
overflow, so the outside water is higher than the inside water). There is
a lot of surface area on the bottom of this container (greater than a
square foot) so I was thinking that I might be able to get away with
silicone even though it doesn't stick well to plastics. Does anyone know of
anything better?
Thanks,
