For the detectives out there....

That's 2 feet below the surface. I'm thinking the white pipe was dropped at a later point as it is sitting a few inches above the pink/grey pipes. Had the white been laid with the other 2 it would be almost touching. My only guess is someone opening a trench for the white pipe ended up hitting the pink pipe with the tip of a pick axe or some other type of tool.

Myself and previous owners have been hemorrhaging money...

What about the water spigots on the outside of the house?
 

Do the outside water spigots supply drinkable water or reclaimed water? and how can you tell?

I can only answer that with respect to my own home - so not a blanket answer.

All of my outside spigots run off the house water - potable water. None from reclaimed.

I would suspect two separate systems? But I don’t have reclaimed water. I would think there are two separate meters with cutoffs You could try shutting off the main feed to irrigation, then turn on the outside spigots. Then do the same with main water supply to house.

Long ago... that’s how I confirmed that all of my outdoor spigots are domestic.
