Lavatories. Precisely the same precautions must be observed in fixinglavatories as have been described in the case of baths, and thesame waste-pipe may answer for both, provided it happens tobe conveniently placed. If more than one lavatory basin shouldbe connected with one waste-pipe, it is necessary that eachshould be separately trapped, and each trap ought to be providedwith an air-pipe to prevent syphonage, as is shown in thesketch (Fig. 83).. In the event of the waste-pipe being common to other lava-tories or baths on upper floors, the air-pipe, A, A, ought not tobe connected, as is shown in the sketch, but it should be carriedto above the highest junction, for reasons already explained inthe case of soil-pipes (p. 121). Cisterns. The materials of which storage cisterns should be made, as wellas the position in which they should be placed, when their pro-vision is necessary by reason of the water-supply being an inter-mittent one, has already been discussed, and the importance ofnot taking the service-pipe to a closet (slop-sink, urinal, &c),direct from the storage cistern, has also been pointed out (p. 20). plumbers work. 129 It now remains to consider how cistern overflows must bedealt with.
