290G Peninsula Tank

haha...it's joint where the PVC screws into my fresh water barrel. It drips every now and then when the pump is pulling water from the barrel. It doesn't when it's just sitting under the water pressure of the tank itself.

I also now hate unions. Is there a perfect way to know they are good. Two of mine leaked and they couldn't be in worse locations to reach. I've redone them and they are fine now but I put a union into everything...go knows how many leaks I will have!!!! It scares the bejesus out of me and all I've got going is my water change station.

With unions on plastic storage tanks or anything non breakable i just tighten them real tight(like until rubber bulges on gasket and plastic looks all distorted). On glass i just go hand tight then a couple wrench turns. Generally if you have a deceint quality union it should be pretty well sealed at slightly past what you can do with your big strong hands.

or you could just order a can of flex seal from the infomercial and coat everything. Did you know that they put a screen door on the bottom of a boat and flex seal made it float

I need advice on a plumbing issue. I just don't seem to be having much luck with plumbing lately so I think its better to ask what people think.

On my return, I divide the 2" line into a closed circuit 1" run that goes over my eurobrace. T's then push the water down through holes in the bracing at the far end from the overflow. I have put unions on both sides of these runs in case I need to remove them. Herein lies the dilemma....where the holes go down, I would like to glue in 90's with threaded ends so that my educators can screw in and help push the water back towards the overflow. If I glue these in, I will not be able to get the "loop" off via my unions anymore...in fact they will be permanent.
Is this the right thing to do? Any alternatives that make more sense?

Already tonight I over tightened the the threaded PVC into my blo-hole pump and cracked the union at the pump. Aaargh!
