NW KS | Very little chemical is left in the meter. Gravity plus the vacuum that pulls the chemical in takes most of it right on through. I believe most of these setups have a valve for water plus typically either 4 or 6 chemical inputs. I ran my homebuilt setup for a year without a water flush valve and never had any issues. I am adding a valve to flush water through but that is more for paraquat than anything else. | |
