I had problems using the garden hose to drain both the sink and shower to my grey water container. I even tried 1 1/4" drain hoses but had problems with the shower drain. I finally decided to hard pipe all the connections. All the parts were obtained from Lowes Hardware store pluming section.
This show to components that make up the shower pipes. They are Keeney Manufacturing company products and were purchased from Lowes and include (part No.):
1. 90 degree coupler elbow (30501wk)
2. one straight tube with the thread nut and plastic ring at the cut end (40-12wk)
3. one waste arm with a 90 degree elbow (104wk)
