I have a job where i did a water service using 1" copper from meter to home, then converting to 3/4" PEX and 1/2" for the branch lines inside the crawlspace, roughed in rerouted kitchen drain and 1/2 bathroom, and installed a Noritz gas tankless water heater outside (far away from gas meter per customer request).
I piggybacked off a junction box in the crawl space using 1 black, 1 white, and 1 ground wire to power a 20 amp GFCI outlet box with weatherproof covering. The gas tankless is hooked up to this outlet.
First thing i noticed is extremely low water pressure in shower. It was fine before i began my work, and i replaced both cartridges already (2 handle shower and tub).
Secondly, after a rain storm, the lights in the home started to flicker, which then led to the entire electricity powering off for a period of time.
Lastly, the hot water in the shower turns cold after customer runs it for 5 mimutes.
Tankless water heater requires 120 VAC. there are so many variables that could be the problem. Please share some insight. My first gas tankless install.
