Good idea. Do you have a floor drain you could run the hose to or maybe a drain pipe you could tap into? Then you could pass on the bucket. Just some thoughts.
if you dump the water out the window why not have a long of a hose to reach the window and drain it from tank directly out the window.. you skip the hard work and let gravity do it's job..
The window is about 25' away in the next room. Its quite simple with the buckets. I dont mind working on my tank. Its the only thing I really have that I enjoy.
