Customer stated that there was a leak coming from her unit to the unit below. Took a look behind access behind tub and found leak coming from waste overflow. Stated to customer that we can replace the seals and trim pieces or replace piping with the seals and trim pieces. Also tub was draining. Slow recommended sneaking drain. Customer agreed to replace piping with wasting overflow trim pieces and also sneaking drain. Went ahead and installed new piping with new pieces and ran tub gun to clear stoppage in drain. Tested and didn’t notice any leaks at this time. Also caulked around trim pieces in shower. Found that by overflow tub is cracked and don’t know the extent of the cracking. Also, very common for cast-iron tubs because where they drilled overflow will be a weak point for the tub. Stated to customer to customer that if cracks are all the way through water can get and leak out that way. Told customer keep an eye out for leaks. Cleaned up work area.
