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?

Have you tried the manufacturer's web site? 'Course you will need the
brand and model number :-\
We have done what you recommend. My daughter was trying to get a
plumber to perform the mainenance, but one doesn't install nor wprk on
tankless heaters. Another didn't want to perform the maintenance, but
wanted to enlarge the gas line and install a new heater. The gas line
meets the guidlines shown in the manual.

It takes an hour to flush the heatexchanger and clean the strainers.
The heater has been neglected, but if a new one is required, the price
quoted was excessive, like $4500. I am looking for a plumber that
will work on it.

I watched the you-tube videos on flushing one and I am willing to do
it, but I would like better information before I start.

Thanks for responding.
