Well My house has a cinder block foundation, and I can't get under this part of the house as its only about 10" from the ground. I want to know how I can test the floors to see if they can handle the weight of my 125
I do not know this,but can find out tomorrow. Our house is 105yrs old,would it be best if i just moved the tank to a place in the house I can get to and brace it
Naw...The older houses were better. Back then a 2x6 actually measured 2 inches by 6 inches. Oh, yeah...they were wood, too. As long as they are 2x6 and spaced 16 inches apart (on center), you will be fine. Just make sure the tank goes across them, not with them. Also, try to put the tank against an outside wall or over the main beam if possible.
2x6 is a bit small for floor joists. Houses 70 years ago started to use 2x8 at the smallest. 90% of houses were made with 2x10 or 2x12 douglas furr. Very strong as long as there are no defects in the board such as a knot. I would say you will be fine. Most homes now a days are better because of the types of materials used. New I beams were designed to increase dead load capability. Standard is 16" OC.
