I think he means opening the WH drain valve with the pressure on to blow out any sediment. I am on a well and have a lot of minerals in the water. I do this about twice a year into a 5 gallon bucket. I get quite a bit of crud.

Makes sense now. I've seen issues with the filter screens at the base of gas WH's because they don't get cleaned- that was my first thought......
