I am new to this group.

I am looking for information concerning maitenance on tankless water
heaters. My daughter has one that needs flushing and the periodic
maintmence performed. The local plumbers don't work on them and the
big city guys want an arm and leg, stating that various items are
required. They want to replace the heater at a cost of $4,500. We
think before replacing, the flushing and strainer cleaning should take
place to see what happens.

I suspect there is a knowledge base concerning these things, but I
don't know where to find them. Can anybody help?
