Shallow underground pipe

[rowdy235]

Hey guys,

I am wanting to put in a hose spigot at my shop for washing cars and flushing boat motor etc. My shop is about 100’ away from my pump house, but the septic drain field runs between the two, so digging deep with the pipe is not really an option.

I was thinking about burying the pipe pretty shallow (like 6”) and putting a shutoff inside the pump house. In the winter when there’s a chance of freezing I would turn off and open the valve on the other end. I already have some pex left over from a project that I would be using.

Just wondering if anybody has any ideas or sees any issues with my plan?

I have a long run of poly to the vegetable garden buried about 6 inches deep across my septic field. I blow the line out in the Fall using an air compressor.

trapping water might be an issue, or forgetting to blow it out soon enough. not as good as being properly buried . but i think you can pull it off without issue you could even sleeve it in a conduit and pull a new line later if you never want to dig again

Thanks guys, sounds like it’s feasible at least. I have some slope between the pump house and shop so that should help with draining the water. We don’t have too harsh of a climate here in my neck of the woods- so would really only need to be worried in the dead of winter.

thanks!

Any water trapped in a belly should not damage PEX. A decent compressor would blow out all the water. Not blowing it out soon enough would mostly affect above ground sections. It takes a long time for frost to penetrate six inches.
