Repair to pressurised pipe

I would appreciate some advice from the knowledgable people on this forum

I help out at a local football team where we have a weedkiller/fertiliser sprayer ' It is towed behind a small mower and powered by it's battery.
Getting it out of the garage I caught the pipe snapping it out of the tee junction
The crack is as per the red line in the photo

The plastic is quite hard (not soft like a nylon waste pipe) so I used a 'super glue' - It went back together well and I thought it was fixed
However when connecting back up and pressurised, there is air/fluid bubbling out of the crack.

Could anyone give me some ideas please on the best method to repair fully
I was wondering about a gauze wrapped in a figure of eight around the tee junction and fibre glass
Or is there a better way?
Thanks

its solvent welded together, to fix properly you would need some pipe and a tee and straight then chop it out and replace.

Try some Qbond, it’s amazing stuff. Glue it together, takes 7 seconds and then poor some of the powder you get with it over the crack and then drop a few drops of glue on it. It will be hard as nails.

Could it be melted with a soldering iron?

Thanks for the ideas guys - I wondered about the soldering iron - just thought being a 'hard' plastic it may not melt well
No harm in trying first I guess

Re renewing the tee piece - Not sure how I would go on with the main coupling at the top. I'll have to see how it is fixed in

Would the Qbond stuff work without breaking the joint again?
 
Pipe solvent cement will melt the plastic and seal the crack, just make sure the crack and pipe are dry before hand :thumbsup:

+1 that's how the are joined in the first place. Handy stuff for repairing snapped clips etc too if they are made of ABS.

Quick update
I took the plunge and had a go with a soldering iron - seemed to work a treat
I'll couple it up later in the week (if it ever stops raining!) and see if it has worked

If not I now have a small recess so will try the pipe solvent as suggested

Many thanks for the suggestions :thumbsup:
