Hello everyone,
I recently purchased a new house and replaced an old system with a new sub-surface drip irrigation system. One zone required that I use the piping from the old system because it passed under a large flagstone patio, leaving me no way to bury new piping to this front yard zone.
Upon trying to connect the old pipe to the new pipe installed under the front yard I found that the old pipe was just a tiny bit too large for the standard 3/4" connectors I had been using. I went to Home Depot, found someone who seemed knowledgeable in plumbing, and we were both at a loss. We could not find anything that fit into a piece of the old pipe (slightly larger than modern standard poly).
He suggested that I use a brass barbed coupler and shrink down a piece of electrical shrink wrap on the side meant for the old piping. I did this, but after two weeks this connection has burst (the system is at only 40psi, btw).
By chance does anyone have ideas about how to make this connection? I'm guessing that it's fairly old pipe and standard sizes were slightly different from back then, but I cannot find any evidence of this after much time searching.
Any help would be greatly appreciated.
Thank you,
Joe
