Atlanta gas light notice a leak on the gas fuel line the feeding to the front of the house lamp lantern. I go down under the crawlspace and cap off the feeding supply line to that lantern. The crawlspace have a very low entrance of 1 foot height very difficult access. Customer have little to no hot water, low water pressure on the hot side of the fixture. Electric water heater is 15 years old. I replace the water heater with a 50 gallon tall electric water heater and bring everything up to code. When I go under the crawlspace, I noticed partial of the house is galvanized pipe waterline. The pipe is very corroded and leaking. Also, the inside of the pipe is very corroded. Have very small opening giving low water pressure to fixtures. I recommend customer to do a whole house re-pipe.
