Arrow Best, simplest and cheapest way to replace pipe?

Hi,

The photo above is of a drain pipe. The pipe is low volume so much so that I intend to reduce it and bury it.

My problem is that the pipe has an elbow attached to it. I would like to remove the elbow leaving the original pipe onto which I would stick a new elbow. The problem I have is that the product used to glue the two items together is called Tangit and I am told that this cannot be undone.

If anyone has any ideas on who to best approach the problem please let me know. I am not very technical in these things.

Thanks,
Alan

Below is what I've been told and areas of research. I've placed them down here so as to avoid a lengthy question.

I found a couple of videos on youTube describing how one can break them apart effectively heating the inner pipe and then ripping it out with a long nose pliers. The challenge using this method are:
  1. The pip is positioned horizonally not vertically
  2. I am told that pipe cement and Tangit are diferent products.

Someone suggested I open up the area and cut where the elbow is inserted over the pipe. Anyway the new elbow must be placed further in. This sounds very plausible but is there a tool (based on a hacksaw) that allows me to do this without having to break a massive portion of the wall?

Can you not just cut the vertical pipe to within 2" of the elbow and attach a coupling and new pipe? You probably won't be able to take any of this apart. Is this your condensate drain?

I wouldn't try to undo any of the connections. Typically a solvent is used, which basically fuses the plastic. It's not like a glue that could be loosened.

I think Larry has the right answer, just cut the vertical pipe, sand the paint off of it, then connect your pipes going onward from that point.

What is this a drain for? Typically reducing the size is not done to pipes, there may be a good reason it's this size.

Thank you for your replies.

The pipe is used to drain rain water. The amount that will come out is VERY small.

My problem is that I need to cut AFTER the elbow as I could not find an adapter that fits on top of the elbow.

If I go for this route, is there a tool I can purchase that will allow me to perform this cut without having to break a large portion of wall? A standard hacksaw will not fit because the elbow is within the wall cavity.

A dremel tool with a cutting wheel would be a good choice for that.

I think this tool will do the trick.

Thank you Kiton.

DOn't try to cut this back in the wall. Cut off the vertical pipe and join a new pipe with a connector, and route it the way you want it. In addition if it carrys rain water, don't reduce it, although you may only think a small amount exits, it may need the full volume at some time.
