Installed a new 50 gallon lowboy electric in customers crawlspace. Previous tank had been removed the day before. Started by digging and using the chipping hammer to make room for the new tank. Once we got about 6â€ deep we spread sand and packed it down to make a firm bed. Placed 6 pavers and poured more sand, packed it down to provide stability to the new tank. Got the new tank in place, level. Cut the old gate valve out and soldered in a new ball valve. Extending the copper water lines about 4 feet so they could reach he inlet and outlet of the tank. Added new supply hoses to both hot and cold. Ran the T&P relief drain line out of the crawl through an existing opening that already had a gas line going through it. Opening is 10â€x6â€. Strapped the tank with earthquake straps and began filling. Checked for leaks. Began connecting the wiring. Checked for leaks. Once the tank had filled, I relieved air from the line through the kitchen and bathroom faucets. Returned power to the tank
