I have a sprinkler system in my yard that was there before I bought it. When I had my pool installed I had to move a sprinkler head/line and lost a few heads along the process. I have replaced those with ones that are easily adjustable and pointed them away from my pool. However, some of the remaining sprinklers are being directed towards my pool walls.
My question is, is this bad for my steel pool walls? I would think it's not ideal but should I go through the trouble of reaiming/replacing the heads so that they dont hit the walls? Or 20 minutes a day, 3 days a week wont do too much damage?
The sprinkler heads in question are a K-Rain type (not sure model) and I cant figure out how to adjust them properly.
