I have 2 tie rods that are slowly leaking during heavy rain or when I water the grass in the basement that need to be repaired. I'm also interested in either a backflow preventer or sump pump for the basement and would like to get the main water valve changed from a twist to a lever if possible. Thank you

Water coming in through basement floor when quick melt or heavy rain.
Project Location: Markham, ON
We had water coming into the basement from two areas during the big melt on Wednesday. We called our insurance company who sent out a restoration specialist who estimated less than 3500 in damage but that the source of the leak is two possible cracks in the foundation. Interested to get your opinion on the source and how we can fix the issue.
