I had the end cap crack on a 2" irrigation line buried 1-2' underground. It sprayed downwards, clearing away 2' of dirt vertically (3-4' total downward now). I found an area about 3-4' away from this site that also had water rushing up from it, so there is at least a 3-4' deep horizontal hole as well, all within feet of my patio and pool pump cement block.

How do I fix this?

I live in Tampa, FL. Ground is kinda of a dry clay/sand kind of dirt.

Right now, my idea is to carefully dig up where I think the hole is so that there's no cavity down there. Flush the broken line. Re-PVC-glue it was a new end cap. Refill hole it with some clay/compact dirt filler.

I think your suggestion/idea is the solution. Unfortunately, when it comes to filling in earthen holes with earth, it's a very simple operation involving digging tools and excess clean fill.

Personally would excavate around and fix the broken end cap, and backfill. It's no more complicated than that.

TL:DR = Grab a shovel and order some dirt.

    Done and done, thanks for the confirmation! I was nervous at first b/c I had to remove some trees and the proximity to the house, but DIYed it. Dug up the area, confirmed the cap had cracked..sawed it off and replaced it. Took 8 extra bags of dirt fill to pack the hole back up. I almost filled with gravel but read it was a bad idea that could worsen erosion.

  • Congratulations! Going slow and doing things by hand in cases like this are often the safe and conservative way to do things. I'm sure you're glad it's done. Mar 13, 2015 at 12:45
