I am adding a filter to my sprinkler system. Since installing the system I have had a problem with sand stopping up the pop up heads. The water source is a shallow well. The lines are 1" and I was told the pump provides around 20 gpm. The T style filters I have been looking at are fairly long with a drain on the bottom.
If I install a 1-1/2" filter, will I get a higher flow rate? I don't want to lose any volume and minimal pressure.
Also, can I mount the filter almost horizontal (tilted slightly down) so I can easily get to the drain valve? If I mount it vertically, the drain valve would be 1-1/2 to 2 feet below the ground and would be hard to get to.
From my reading, I assume I need a 100 mesh filter. I am looking at the ones at the link below. Are these good filters? If not, can anyone suggest better ones?

Thanks in advance for any help or advice.
