[al's sewer]

I want to re-locate my water heater into a utility closet and finish the basement. I want to move it 25 feet and put it next to a concrete wall. Does code require a nearby floor drain? Can I put a pan under the water heater and drill a 1" hole thru the basement floor to drain the water from a water heater problem into the 8" of gravel that is suposed to be under the slab?

you would have to check your local codes. Here in missouri they are not required but I would suggest it to avoid a mess if the heater ever starts leaking or the t and p blows. As far as drilling the slab the key word there is supposedly.
