Replace 3/4hp garbage disposal with new 1/2 garbage disposal Upon arrival customer explained that tankless water heater was having the same issue and his garbage disposal was also leaking after getting his approval I started flush on tankless at no charge being it was less than a month ago when we did so while it was flush I replaced 3/4 garbage disposal with 1/2hp garbage garbage disposal was extremely rusted and difficult to remove after getting installed tested and everything is working properly with no leaks After garbage disposal was replace I flushed tankless with clean water and put back in service and found that flame rods are bad cleaned and reinstalled and fired up but can’t say how long it will last gave customer price to replace and supply is checking availability being unit is so old
