Seal a sump

[shibumi]

Hi Folks -

We just got a used wet / dry and there's a little bit of water we can see collecting underneath it (between the wet/dry and the stand).

At this point, we're not sure if it's an actual leak or just some residual water from the setup - but the area seems to be getting slightly bigger...

If we want to reseal the all of the edges of the wet / dry, what is the best thing to use to do that? Brand name - and where we can buy it...

I'm assuming some sort of silicone - but I'm not sure what would be safe to use inside the sump. Thanks for the help.

NO SILICONE...Weld On #40.
Yo checkinhawk...what do you think???

yeah id agree on the weld on 40 or something close.i think the thicker stuff will work.you can call GE plastics,they are on 49 st n and carry weld-on.

From my quick looks on google for Weld On 40, it looks like it's used to join two pieces of acrylic together - will it still work in our case where the acrylic is already together, but has a tiny tiny leak?

I'm picturing something like a "caulk" where you would just put a bead of something along this already existing seam. It appears to be coming from somewhere along w/ the side is joined to the bottom.

Could we use the Weld On 40 for that? I don't want to actually take the wet / dry apart and re-glue it... (if I don't have to).

The leak is so small that even overnight there is no water that has made it beyond the plastic that is under the wet / dry - but the wet spot itself has gotten bigger (from starting at 1" to now about 6" wide today.)

get the weld on,just apply it just like you would if you were resealing the inside.there is no need to take the sump apart.if you go to GE see if they have some 1/8"acrylic square stock,you can appy the weld on to the stock then place it into the leaking area.

I concur with Checkinhawk, Ive repaired several acrylic things by adding Weldon into the corner. The square stock would be a great idea to ensure a GREAT seal is formed.

If you want to set it up as a sump/fuge, you need to dry it out anyway, so buy some cut acrylic for the bottoms of those baffles while you're there.
