So wide a range is possible in the selection and price of plumbing fixtures that no very useful data can be given for a complete installation.

For instance, in one house the price of a single bathroom, fitted up to meet the fancies and purse of the owner, may cost more than the whole plumbing outfit of his more modest neighbor.

Nevertheless, it is a fact that the plumbing of a house is a poor place to practice economy, as no part of the construction of a building needs more careful attention in execution or in selection.

In general, a good job of plumbing will cost about 10 per cent of the cost of the building, and of this outlay about 30 per cent will represent the labor.

In taking off plumbing the contractor should begin at the sewer or cesspool, if the drains are included, or, if not, at the outer end of the soil pipe, and take off carefully every pipe with its fittings, which should be itemized carefully as this data will be useful in getting at the amount of caulking, fitting, etc.

Soil Pipes. Soil pipes should be estimated by the lineal foot, allowing in each joint 3/4 of a pound of lead for every inch in diameter of the pipe.

List prices of pipe and fittings can be obtained from the dealers, which are subject to discount; these vary from time to time, but the present discounts will be found to bring the prices of the more common materials about as follows:
