Q. Inclosed I send you the plan of a house I have just fitted up with a circulating-boiler. The boiler is set about four feet above the range in a closet. Now, the landlord has built a summer kitchen, and wants a water-back put in to heat water in boiler from outside range, and I tell him he cannot do it unless he cuts out the back of the range in the main kitchen and runs the pipes back of the range in the main kitchen. But the range man says we can run down from the water-back under the beams to inside boiler, which will cause about two feet of a trap in the circulating-pipe. I say it will not work. Please tell me who is right. I was always taught that the circulating-pipe should have a fall from boiler to water-back. Please tell me which would be the best way to fix it to make a job of it. By answering this as soon as possible you will confer a great favor.

A. You are right, and the range man is obviously wrong. There should be a gradual ascent from the water-back of the pipe that conveys the water heated by it to the side-coupling of the boiler. If the ranges and boiler are located as shown in the sketch, we see no proper way of connecting with the summer range except to run the pipes behind the large range.
