    Before you blame the uni feeder isolate the water feeder and have the ho check the water level if it doesn't rise then it's not the feeder if it does then you probalby have a small leak on the tankless coil isolate it to be sure and if the level does not flood then there's your culprit ,i have seen this a few times on steamer it's sometimes overlooked it can be a bit easier on a hot water boiler it blows the saftey but the procuder is the same peace and good luck clammy
