On arrival the customer showed me the tankless water heater and main emergency shutoff valve. I checked the breaker box for proper sizing as well as check for the drain line for the new tanked water heater tmp. I wrote up an estimate to put in a new water heater with water heater emergency shutoff valve and a permit. After presenting the estimate to the customer and going over the work I would be doing and the warranty that comes with it. The customer declined the estimate and stated they were quoted by another company $1300. They will call back if they would like to move forward because the estimate given by the company that quoted $1300 does not state any warranty or drain system.
