Need to replace a T'd in tank in house garage closet..Is on its stand
with pipe running into hole in stand. Can't see underneath. Outside
tank at T looks like pipe screwed in. How do you access under tank and
disconnect the tank to be replaced after emptying tank? Is about 25
years old. Probably around size of WX200-250. Any help on disconnecting
pipe would be appreciated. Is there a trick in getting in there or what?
