4. Place the two brass closet hold-down bolt heads in the slots of the flange.
5. On the bottom of the water closet, as shown in view A, figure 5-8, slip the preformed sealing ring over the horn to form a sealing gasket for the water closet against the face of the flange. Do not use putty as it will dry out and leave a possible sewer gas leak.
6. Turn the water closet bowl right side up and set it on the flange with the horn projecting down into the flange. In setting the bowl on the flange, as shown in view B, figure 5-8, guide the two hold-down bolts up through the bolt holes on either side of the base of the water closet. Using your full weight, press down and twist slightly to settle the bowl and the wax ring into position. The bowl should be perfectly level when settled. Check for level. If off level, use a wedge.
7. Install nuts on the hold-down bolts and tighten them alternately. Do not overtighten them as this may crack the base of the water closet.
8. A wall-mounted water closet, as shown in view A, figure 5-9, is attached to the wall by a chair carrier, similar to the one shown in view B, figure 5-9. The chair carrier is positioned and bolted to the floor. The foot carries the weight of the entire closet independent of the walls and drainage connections. A standard fitting is used to connect between the drain and the closet bowl after the chair carrier is bolted down. The fittings are for 4-inch iron, lead, or soil pipe. The bolt holes in the chair carrier are slotted to facilitate installation of the closet bowl.
When mounting a close-coupled tank on a closet bowl, note that two bolts hold the tank on the bowl. Figure 5-10 shows how. The water supply pipe is between the bolts and drops the water directly into the bowl. A specially designed gasket is installed between the tank and bowl to make the connection waterproof. The bolts are tightened from underneath the closet bowl. Do not apply too much pressure when you tighten these bolts, because you may crack the bottom of the tank or the back of the bowl.Continue Reading
