I have a Sinkmaster Instant 190* water heater that is about 3-5 years old, and since a plumber tightened it in its socket, water is not heating to the proper temperature. It’s possible we just didn’t notice the heat drop before the plumber tightened it. Is there a way to adjust/increase the temperature? Thanks, Pat
I tried to find Sinkmaster on the web to ask them about the problem but they don’t have a website. I bought the Instant 190* at a store that has now closed – Home Depot purchased and inhaled it and it disappeared. I haven’t found HD employees to be particularly knowledgeable about these things, so while searching for Sinkmaster, I found your site and contacted you. I’d appreciate any help you may have to offer.
