Sorry for the slow progress. Hurt my arm which is slowing me up a bit. You can see the lion’s share of the plumbing is done. 2” Radials of shortening lengths coming off of a 4” header all tied together to equalize flow, I hope.
Each radial will have a clean out. The right side of the picture shows a 4” clean out as well. The header will be in that trench that is filled with rain water at the moment so I had to lift it a little so I could glue the joints. With a little luck I’ll have the plumbing finished tomorrow night after work.
