Clog in a 2000ft agricultural pipe - Best way to find it?
Hello all,
I have a piece of farmland in California that we flood irrigate from a series of 9 valves on a pipeline some 2ft below the soil. Over the last several years it has been taking longer and longer to irrigate our pasture and for the life of me I can't find what is happening.
This is what I have done and know so far:
- bought a small pipe camera with 50ft of length and scoped every valve on my piece of property (marked with red dots on the picture)
- also scoped the three valves on my neighbors property (marked with yellow dots on the picture)
- the pipe is all PVC
- my neighbor's upper pasture (surrounded in yellow line) does not seem to suffer from slow discharge out of his irrigation valves
- it isn't a true clog because we still get flow - but what use to take 8 hours now takes 14 to flood our whole pasture and has been getting progressively worse over the last few years.
Some genius back in the day thought it would be wise to plant oak trees on top of the pipes in the lower pastures (both mine and my neighbors) back when I was probably watching Ninja Turtles, but every length of pipe I scoped showed no buckling or break in the pipes.
There are no trees on the pipeline anywhere else that could be throttling it other than the marked red and yellow dots - which I have scoped up to 50ft in both directions.
What should be my next step? Do I rent a sewer scope from Home Depot and hope the clog is within 200ft of somewhere I can access it? Is this something a residential plumber could come out and solve with more sophisticated equipment?
Thank you all for any help!
