7Check your storm water drains
This first one is easier than you think. I’m not talking about sticking your hand down the drain or a hose down to see if it flows well. A simple visual check that you can do is to take a look at what material is at the bottom of the downpipes. If it is white plastic pipe, then it’s safe to say that you’re in the clear and the drain has probably been updated. If it’s an old brown terracotta pipe, chances are that it’s probably full of roots or has even been crushed by a couple of tree roots somewhere along the line. This can be a costly thing to have re-done.
