Just wondering from others experiences what works the best for adhering PVC to blue barrel plastic? I would like the bond to last for a long time obviously.

Was thinking a general acetic cure silicone.... Would sikaflex be better?

The surface is going to be inside my GB's so will be in contact with GB water.

What are you trying to do? Plumb a standpipe? If so, what about a uniseal? Use a holesaw, insert uniseal and push thru pipe. It will be water tight.

i have to agree with arbe, a mechanical seal is best

if you have to use a chemical seal then silcone and sikaflex are probably on a par with each other

Thanks guys,

Yeah was plumbing up a male 19mm hose attachment into the bottom of the half-cut blue barrel as the outlet for a loop siphon. I'm surrounding the inlet with a ~60mm (can't remember precise diameter off-hand) PVC standpipe/media guard, so I want to adhere the standpipe to the base as well as make the male outlet watertight.

I've done a fair bit of searching, but have found it hard to determine exactly what combination of parts people tend to use for this application, whether it's a uniseal that couples with the standpipe and is then reduced to allow attachment of 19mm hose, of just the hodge-podge ghetto style combination I'm thinking...

I've read that silicone adhesion will fail after a year or two and may leech, but perhaps this is just paranoia?? I just don't have the experience to know what to do.

Any links to memorable/elaborate solutions/examples of standpipe & loop siphon outlets would be appreciated.

Thanks !

There is a good manual on making an entire aquaponcs system out of blue barrels. I did a quick search but couldn't find it. Perhaps someone knows where it is.

It may give you ideas.

Edit: found link.
