I have had my tankless water heater for around 3 years now and have yet to flush the system. I am on a well system and my water is a little hard. Should I just do a basic flush of the system........ or I have heard some kind of flush deal where you use vinegar to clear out any scale within the pipes.
Anyone ever hear of this, or anyone have any good tips?
Don't know what brand you have.. Rheem ( I'am sure others also) has a flush kit comes with circulation pump to perform a vinegas / water flush.. Does your"s have the flush valve kit installed ?
