in Domestic Hot Water
Hi Everyone, I have a Trianco heat maker II model HW-M2-100L. I'm having very low DHW pressure at all faucets/ showers on 1st and 2nd floors (All HW locations in house). It is the original installed when we built the house in 1994. Hate to ask but........... any thoughts?

    Just the hot water? Is temperature OK, or is it too hot or cold? Assuming that all the valves are open as they should be, my first idea would be that the domestic hot water heat exchanger coil inside has gotten scaled up. Has it ever been flushed out? Descaled?
