Now run your plumbing making sure cold water fed and hot water out is right. You may want to have a bucket and run cold for a second to clear pipes of sediments.
Step 8

Connect your plumbing, turn water and power on and run hot water for a minute or two before replacing aereators, shower heads, and washer hoses(place hoses inside washer or drain pipe as not to flood your washroom). Now you have successfully installed your money saving tankless hot water heater.
