HI – I watched your video on how to descale a mastertemp 400 and I think I need to do it (out tankless waterheaters in our house died because of how hard our water is here in San Diego)…my heater keeps kicking on and off. I just changed out the AFS and its still happening so I think my exchanger is full of scale most likely. I am a DIY guy however, and the idea of taking apart the couplings, gas, etc. to move the heater seems scary to me. Is there another way to do it?

We don’t move a heater to descale it. We just loosen the unions connecting to the heater and run the water through an isolated heater. It’s a bit of work and you need the right set up fittings but it can be done in place.
