hot water in all tubs but not sinks

[dkw1977]

I have a issue I need help with. I live in a four bed 3 bath home. Came home today and there was no hot water in any faucet in my home but there is hot water in all three tubs. Enough hot water where I was able to shower. This is strange to say the least. What can possibly stop hot water from getting to every sink in my home. The water gets lukewarm but never gets fully hot like it was yesterday. But the tubs are flaming hot. Please help!!!

Sounds like you have a tankless water heater and the flow switch is not working. Try turning on the tub along with the sink and I bet you will then get hot water to the sink.
