How to fix cracked reticulation piping?

[cyberbash]

This is probably a straightforward question, so apologies but I'm new to reticulation so I'm not sure where to start.

It looks like someone has driven over a part of the reticulation and as a result there is a crack (pictured). I can see a Ratchet Clamp holding two of the pipes together but I'm not sure what the part that's actually broken is called and therefore how to replace it. The bit that is cracked seems to be attached to a circular black disc beneath it, but again I'm also not sure what that is and if that also needs to be replaced.

Thanks for your advice

Hello @cyberbash 

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your damaged reticulation piping.

I'm going to have to ask you to dig further into the soil in order to reveal what the entire part looks like. It appears to be a standard 90-degree elbow that is on some sort of standing plate that prevents it from moving. It could also be a plug end with a footing. Either way we'll need to see the entire structure in order to tell what it is. Once you have it out of the ground, please take a photo and post it here. We can then do a search for the part that's been damaged.

If you have any other questions we can help with, please let us know.

Hi Eric, thanks for the reply and for the warm welcome. I’ve taken some more photos-it seems like the black pipe just plugs into the white pipe. The connection seems quite snug and I can’t see any fasteners so it may be glued in?

thanks again

Hi @cyberbash,

The damaged black plastic part appears to be an irrigation riser with an elbow joining it to your poly irrigation line.

The piece underground is a PVC pressure elbow which will be glued in place. 

Unfortunately, you are going to have to cut it off and replace it with a new one as the irrigation riser is glued into it.

If you can advise what the diameter of the poly pipe and the PVC pipe are, I am happy to recommend a suitable replacement.

Let me know how you go.

Hi Jacob,

the black poly pipe is 2cm diameter and the white PVC pipe is 4cm diameter. If you could give me detailed instructions/post a link for how to replace it too that would be much appreciated-I’m not very handy but want to learn. 
Thanks

Hi @cyberbash,

It looks like they've used a K-Rain 19mm Barbed Elbow × 15mm BSP Female at the top of the riser. This would mean the riser is threaded into the underside of this fitting. If you rotate the riser anticlockwise, does it move at all?

If you can rotate this piece out, you may be able to do the same at the base of the riser meaning you could just replace the riser.

If this is not possible, I'll still need a bit more information to be confident with the materials.

Can you advise the diameter of the PVC pipe at the base of the trench? 

Fingers crossed you can just rotate the riser out of place, but if not I should be able to get you the parts you need with this further information.

Let me know how you go.

Jacob
