Ed, I am in the York, PA. area, I do work in my surrounding area as well,do yourself a favor and get a pump, they do a much better job. By circulating the chemical through the lines, there is also friction caused by the circulation, that helps the chemical work better.Ther are cheaper pumps on the market, in fact I build my own using 50gph carbonator pumps.As far as pricing goes, you are somewhat limited to what the other guys in the area charge. If I did what I do in Philly or Pittsburg, I could charge a lot more than I do in York or Lancaster counties.
