Around the Northwest, these 3-Rock Column Bubblers are pretty popular. I've seen them in different parts of the country too but I don't know how popular they are in all areas. Anyway, as my guys were installing this feature, I decided to stop by the jobsite and take some "during" photos. They may be of interest to some of you who haven't done these before. This is how we do them..... (Before you reply, give me a few minutes to post all the photos) These first photos just show the hole we dug, the valve box at the bottom that holds the pump, and the first column. I had requested a 4' column, a 3' column, and a 2' column. But what I ended up with was 2 4' columns and one just under 2'. The customer distinctly wanted 3 different heights. So we had to improvise. We ended up just buring the first 4' column 1' deep - then it became a 3' column. That's what you see here in these first few photos. .
