safari. I found three major cracks so it is to be replaced. I measured every angle I could think of and now have a few questions. Does it need to be replaced with the same size? Since the opening in the space we removed it from is 54 by 28 by 7, could the tank also be increased in size. Where would I be able to have one made? I was also wondering if this was this the original tank, red seems like a strange color? There is a Styrofoam bed under the tank and the tank was screwed to the floor and the flange is cast iron. I wasn't able to get it off when I removed the toilet so it is still attached.
Thank for you help.
Increasing that tank size would create a number of issues.
The styrofoam bed and around the sides are for cold weather insulation.
There should have been a small hose hooked to the tank pan, that came from a heat duct, so that when you ran the furnace, a little heat went around the tank to keep it from freezing.
The original floor flanges were cast metal.
A fiberglass exact replacement is available.
