<div>My heat pipes are not hooked up. 2 problems. We
tried one section and heated with 2 electric 40gal hot
water tanks. Electric bill was over $600 !!!! Then the
pipes were early pex that has set in an open warehouse (
supplier"s ) and became brittle soon after the concrete
was poured. I think they will still be reliable if not
moved a lot.. Too much investment in that heated floor
to just abandon it. I picked up a gas ired swimming

<div>I have thought about that, and
have an old and a newer 4 post

you work on both trucks and

way. I would like to install the
4 post 30K lift, but the floor has
water pipes for heat under the
slab. We don't know where they
are, and the posts have to have a
pier under them. The floor has 8"
piers under the slab, cannot
remember where they are. I
thought of fastening 4' x 4'
plates 1in thick to the floor and
then fasten the posts to them.
The floor is reinforced with
reinforcing steel. I need to find
the reinforcing in the floor and

My experience
with Cat, IH,

An interesting

that, rarely
