Upon arrival customer stated they wanted to make sure the sump pump worked in the basement and to see why the shower was leaking. I filled up a 5 gallon bucket and make sure the sump pump work. The sump pump is working properly. While I was testing the sump pump I had the shower running. I was not able to get the shower to leak until I ran the water on the side of the shower where I saw missing grout on the shower wall. I informed the customer they would have get a tile guy to fix that issue. Customer also stated he was concerned about the cast iron so I left customer with estimate to replace all the cast iron inside the home.
