Greywater

Made this grid out of 2" PVC pipe. It 51" by 24" which gives me about 25'. I found a program that figures the volume of pipe and it comes to 4.7 gals. I am planning on installing it under my teardrop between the 2" tubing. I have the inlet and outlet but will have to vent it.
Here is a link to the neat program for figuring the volume of pipe.
