Well casing adapter to drop pipe connection method?

[Ryan81]

Hello gentlemen...
Thanks in advance for your time.

I have a deep jet well, single pipe in 2" casing, with a 1hp Sta-rite vertical pump. It sits on a Sta-rite casing adapter j216-21 like in this link.
Sta-Rite J216-21 Vertical Bolt-On Well Casing Adapter, Iron #VORG6114912, J216-21 (shelllumber.com)

The 1 1/4" drop pipe had belled connections, and the casing adapter has 1 1/4" threads.

My question is what is the preferred method for transition from the drop pipe to the threads in the casing adapter?

If I remember correctly, there is a special heavy pvc adapter that is specific for this due to the weight it supports, but can't remember what it's called, and can't find one anywhere.

Can anyone provide a link to this piece, or the name of it. Or at least an alternate method to attach this downpipe to the casing adapter?

Thanks-

Ryan

I guess there are male threads on the adapter.
While you could use a schedule 120 or 180 pvc coupling, you probably want to use a stainless steel coupling. It is not bothered by overtightening, which a pvc coupling could be split by.

How do you transition from the stainless coupling, to the slip joint pvc to give it the needed glue surface area to support the weight of the downpipe?

Sorry. I misread. I had been thinking threaded schedule 80 PVC rather than glued schedule 40. Is that glued drop pipe recommended for use as a drop pipe?

depending on what the adapter needs.

I am not a pro, and you should get additional thoughts.

Perhaps you are thinking of a short section of threaded Sch 120 PVC pipe, threaded to the adaptor, and the cut end glued within the bell end of the drop pipe.

I don't find info on cemented 1-1/4 bell-end drop pipe.

Thanks for the tips. Yes, this is schedule 80 drop pipe- it's specifically used as drop pipe. The fittings you listed would make the connection, but lack the strength to reliably support the drop pipe or not crack during the pulling of the well, because of lack of glue surface area in the slip end of these.

What is the OD of the bell? Do you have a link to that drop pipe?

You could thread the pipe.

This may be the best option. I'll go by the well driller tomorrow and talk to him.

You could thread the pipe.

Hmm. Maybe it is not drop pipe, but just heavy pvc universal pipe. It is what the local driller here uses. It's like the one in this link, but with a slightly deeper bell. I'll have to go talk to the driller, it looks like.

I have not seen any sch 80 with belled ends. My guess is it is sch 120 to have deeper bell ends.

 

[Reach4]

I was concerned that the OD of the bell would leave enough space inside of the 2 inch casing to pass enough water easily.

Figured I would update this with the answer, as not the leave this thread hanging.

The part is called a Special Reducing Adapter, and it is kind of Texas specific. There is also a female one that goes on the jet end (bottom) of the drop pipe to securely attach the jet assembly. Notice the slight reduction in it's size.
