150. Overflows. Keep overflows clean. When the plug and overflow are combined, as they sometimes are, lift out the cylinder forming the plug and overflow and wash it. When it fails to hold water in the tub or basin, it may need a new washer on the lower part. This may be replaced very easily. Fig. 79 shows one type of overflow.
