drip system filtration with ditch water
Hi, I'm using ditch water with a drip irrigation system. I have a 40 mesh filter followed by a 140 mesh filter on each zone. The 140 mesh filters clog almost immediately. I've been told that most drip systems can really work with much lower filtration, like just the 40 mesh filter alone. I am using both built in 1/2 gph pressure compensator emmitter line and some punched in 1/2 gal emmitters on 1/2 inch line.
The local hardware store says they have seen 100's of local systems work fine and not clog with ditch water and 40 mesh filtration. What do you think? I don't want to ruin my new system. And if I need 140 mesh filtration, how to solve the immediate clog ups?
