Brandon, many thanks.

I just got an estimate this morning for professional sprinkler installation. The installer hasn’t even sent me the estimate yet…but I’m guessing it’s going to be over $2K as I have a large back yard.

If the bill is too much I may well use your system. I’ve dug trenches for a friend’s sprinklers (sucker moved to Germany so I can’t have him repay the favor), but your system beats running that "Ditch Witch" all day. After seeing your pictures & notes, I think I can do this for a lot less than a pro will charge. Again, many thanks… Dave
