Well. I needed a new holding tank, one was stinkin and only 6 gallons, decided to take advantange of available space so I made one. New one holds 14 gallons and still fits in same location as old one
All said and done I had about $110.00 including hose, fittings and materials.
I posted quite a few pics on my blog, here is the link....i hate resizing pics
so far it holds water just fine
