Old weeping tile
I live in a 90+ year old house with an old terra cotta weeping tile system. There are multiple openings in the ground on each side of the house. They are not attached to the gutter downspouts. Are the weeping tiles serving any purpose? I would really like to close them up as I feel they are breeding grounds for misquitoes, which we have an enormously bad problem with. I can feel standing water in a few of the pipes. It would be expensive and time consuming to try and dunk each tile opening every month. Could I just fill the pipes with concrete to close them up? Or maybe gravel, which would still allow some drainage (assuming some actually work) but no standing water?
Thanks for any help!
