Home Improvement Asked by D.Mac on February 11, 2021
I am installing a mainline for a residential lawn irrigation system. I laboriously dug down to the pipe leading to a yard hydrant, three feet deep. I installed a tee, and on the branch from the tee I installed a PVC ball valve and drain.
To winterize the system I will close the ball valve and purge the pipe downstream but I will need a way to access this valve from the ground surface. I propose a three foot length of six inch diameter DWV pipe.
Is this what is commonly done? (My arm is only so long) should I have used an expensive curb key valve?
Should I use ABS or PVC or whatever I can find? How should I cap this off?
I decided to install an A.Y. McDonald 6001 series brass stop and waste valve (for example, on Amazon, ASIN B003MXYJOU). Such units are much more expensive than a common valve, and I was hoping to avoid that expense. However situations like mine are just what they're designed for.
Reading other answers on the site, it is best to prioritize quality and reliability when making plumbing repairs in difficult to access locations.
