SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

I have an older sprinkler system, which normally works well. It appears to have been put together by some folks who had only small lengths of pipe, or by someone who hoped the house owner would have to keep calling them back to do the repairs rather than doing them themselves. I have no room to work with between 1" connectors, so I cannot cut without opening up a very large hole in my yard and replacing 15-20 feet of pipe. Unfortunately this same area includes several valves which are emplaced on parrallels, and all of it glued together. I would have to replace ALL of the valves also. My first repair with an epoxy I was told would work made for a bigger break than I started with. My next attempt was with a radiator hose whose internal diameter was the same as the outer diameter of the 1" connector. I used hose clamps and they held famously, but the radiator hose burst under the system pressure! More than a radiator, huh? I see this stuff called "funny pipe', but it is of very small diameter. What is there that I can use to effect repairs such as these (this is my second) without digging up my whole yard an replacing all those expensive valves and pipe?

I appreciate your help.
