run drain line well away from home DOWNHILL.
you should of filled the tub and surrounding area with gravel, dirt
just compacts and doesnt drain.
do you have a downhill space to drain too? the flexible black plastic
drain line is cheap and asy to use so run 2 one for downspouts and a
seperate one to a gravel bed in the problem area, just the gravel bed
area should be perforated the balance solid pipe.
