Filter installation help needed

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.

If you are collecting a lot of sand, you will have to live with a highly visible T-filter, so it works according to mfr instructions. For 20 gpm, the 1-1/2 inch size is worth the extra expense

Thanks. I have not seen any instructions yet. Will they state it should be mounted vertically? It is almost 16" long so i was trying to figure out an easy way to see/clean the filter. I am in the deep south so freezing isn't really an issue. Could I tee up above ground, install the filter and then tee back down? Would that cause a loss in pressure or flow? It would not be easily seen so that isn't a problem.

Sure, you can elbow up and back down

Thank you. I will order it today. I am curious though...is there a problem with mounting it at a slight downward angle (maybe 20 or 30 degrees) as opposed to vertically? I assumed the water has to go thru the filter no matter what angle and I would just have to make sure the angle was sufficient for all the water to flow out of the drain.

Thanks again for the quick responses. I am new to the site but spent a few hours on it and have already learned a lot.
