Before I backfilled the trench for my yard's sprinkler system I noticed that water collected in the low spot after use. I assume it's drainage from each zone from the drain openings, The lawn is slightly higher than the valve box so I think the water flowed down the trench. I put rock in the trench before I backfilled it. Will this accumulation of water damage my yard or house foundation?
