Hi, I put a riser on my distribution box over a year ago so
I could pour septic scrub into my system. My question is:
My D-box always has about 1-2 inches of water in it. Is this normal?
I went away for a weeks vacation and came back and there was still about one inch of water in it. My system is working fine and I also put a Zabel filter on my exit pipe so no solids get into the field.
Thanks, 

Jim.
