not to derail this thread....yes I have seen many, many patients because of improper lifting at home. Some in such sever pain I had to heavily medicate them just to get them off the floor.
I had a similiar filtration set-up in my home a few years back and actually utilized drawer rails with a DIY shelf. The whole thing would slide forward 2.5 feet in order to give me full access to all the plumbing and filters.
You see, I am 6ft4in tall and weigh 206lbs, my lanky frame just wouldn't fit under the stand.
