I have a 26 year old tank in my garage that supplies my house. I noticed two days ago that it had been leaking for an unknown amount of time (could be two days, could be four months). Finally got a chance to look closer today and it looks like the seam of the cylinder is bulging and rusted, can’t tell exactly where the water is coming from but deductive reasoning says it’s near the bottom... It is gas heated. I do not have the funds to purchase a replacement right now but luckily it’s summer so hot water isn’t totally needed. I need to know: can I shut off the gas and continue to use my water in my house like normal just knowing I won’t get any hot water? Can I shut off the gas and the water flowing into the tank, drain it, and just continue without replacement for now? I obviously need to replace it, but I can’t afford several hundred dollars right now.
