  • To remove one 75 or 80-gallon tank from inside closet, attic or closet $225 per tank

  • Hard to access attic area where the tankless is to be installed. $350  This is for extreme conditions where existing construction makes the tankless installation very labor intense, occurs only 3% of homes.  

  • When adding the Crossover Valve, for the hot circulation system, we encounter "builder grade" sink valves or stops or old supply line which are old or not compatible with the Rheem Crossover Valve. In this case we must replace the original water supply lines and valves or stops, under only one sink, to assure there will be no future leaks. Install new water supply lines and sink valves or stops  $225.  See pics below. Tankless is not responsible for leaks if we are forced to use existing supply lines or sink valves/stops.

  • Add an 120v electrical outlet in an attic or closet ,if one is not available. $195.

  • For Tankless Guru to change your water filter $125. Includes labor and cartridge.

If you have sink valves or stops, that look these, they will need to
be replaced in order to install our hot water re-circulation cross over valve.
