Saddle hubs belong to the days of poor plumbing, before plumbing codes were adopted. They are used, however, to a greater or less extent in country places where there is no one to supervise the work on repair jobs. A saddle hub is shown in Fig. 6i. To use this fitting a hole must first be cut through the pipe to which the hub is to be attached and two bolt holes through which the bolts that hold the saddle hub to the pipe must be drilled. The space between the saddle hub and the pipe is then bedded in putty and the two, the pipe and saddle hub, are drawn firmly together by the bolts. Such a connection can never be depended on, and is prohibited in all cities where there are plumbing codes. The putty between the saddle hub and the pipe, when once it has dried out, is liable to crack, thus providing a channel for the escape of gas into the house, or the bolts might corrode through, thus breaking the connection at this point. There is no real economy in the use of saddle hubs and the practice of installing them should be discouraged. If, however, saddle hubs are to be used, then it is better to require a pipe band, similar to Fig. 62, which makes a much stronger and more permanent joint. Saddle hubs can be had in T patterns, Y patterns, and in half-Y patterns, and with various sizes of outlet. In ordering saddle hubs, not only the size of outlet should be specified, but also the size of pipe the saddle is to fit, and whether the pipe is to be standard or extra heavy. Pipe plugs, Fig. 63, are used to close the ends of pipes and the branch outlet to fittings. Fig. 64. A cleanout ferrule is shown in Fig. 64. Some cleanouts have iron bodies and some have brass more
