| you did not say how the slate was installed (what is under it, between it, etc) if you are not concerned with the slate cracking or developing differential settlement under load, and if not much is needed to level, hardwood shimms as needed to level under the vertical support points of the cabinet. once satisfied, load up with tank and some water. if all is well, cut shimm tails flush with cabinet. naturally these thoughts are mine alone and not knowing type and capability of slate you have, cannot anticipate cracking of slate etc. fortunately I did not have slate, but, removed carpet, added a 1/8" shimm full length of rear cabinet, since the side walls of cabinet are solid wood no seams, the small gap is acceptable on the ends with front and rear full supported. i will still probably add a shim or two for safety though. if on the other hand all you have is some very minor irregularities in the floor and you do not need to elevate one end from the other a piece of carpet might just do (without pad of course). hope this helps just my thought. |
