Two hours ago, I called Foerst Plumbing who is now Totally Tankless because our Bosch on demand water heater was leaking. Steve just left and he showed us that the original installer did not adjust the fuel and air nor did he t vent the heater properly. Steve is coming back tomorrow to fix the install. In the meantime, my family can shower tonight.

I have a tankless water heater and the Bosch told me to contact Foerst Plumbing. The owner came out to look at my unit he had the parts the next day and I had hot water and a new plumber. Thanks guys.
