Has anyone repaired a small crack in a plastic waterbutt? I tried Araldite but it wouldn't stick to the surface. There seem to be a few possibilities at Toolstation but I wondered if anyone has actually used anything successfully.

I bought some sealing tape on the strength of a Faceache ad'. Wasn't dear, but sealed my plastic downpipe superbly.

Ct1, construction adhesive. It will stick to pretty much every thing except the plastic the tube is made from. One of the demos is sealing a lastic cup, cut with a stanley whilst full of water. Other brands maybe as good now. For about a tenner worth a try

I’ve welded plastic cracks up with a soldering iron for decades. Bit flat tip helps and sort of stir the molten plastic. Also don’t breathe the fumes if you can help it

I think i would be trying 1 of the addhesives mentioned like ct1 but i would be putting a large patch on the inside and smearing loads of it about and try to brace it till it sticks.
Atleast them the water pressure is pushing the patch tighter.
Done similar with feed hoppers and i would do that and then rivet the patch in place but with this water would leak throu the rivets themselves
Must admit even if u welded/melted it i would be sticking a big patch inside.
Never tried welding a water butt but some IBC's aren't very thick, tried welded cracks in wellies quite a few times always unsuccesfully ( althou the cracks wee generally where the welly bends and flexes so always opened up again)

I've done a few holes with a thin plastic sheet/milk bottle patch and silicone on the inside of the butt, just like doing a puncture in a bicycle tyre, which works for that type of repair.

….ask a Creedmoor owner for a loan of his butt plug?…..
maybe not!

Thoroughly clean & dry the inside area of crack, apply CT1 inside, let set, clean & dry outside skin, apply CT1 to outside of crack.
I have repaired pastic water containers by paring off a thin sliver of plastic from an unobtrusive place (like around the lip of the container, or sometimes there's a rim around the base where a bit can be taken from) and using it rather like a brazing rod in conjunction with a soldering iron. So, run the soldering iron along the split to melt the surface while at the same time melting the plastic "brazing rod" onto the area.

As above, gorilla tape, soldering iron, sealant etc…. My weapon of choice is the welly repair stuff that goes iff very quickly in sunlight - name escapes me but I have used it on countless repairs and it is very flexible too.
Just remembered it (well Google did) Stormsure.
