Geberit toilet systems siphon 1.6 gallons of water per flush. Geberit toilet bowl designs, composed of high-density polyethylene tanks, prevent build-up of condensation. The design also consists of an in-wall installation system that minimizes flushing noise levels, saves nine inches of floor space and eliminates the toilet base, a prime target for unforeseeable messes. The fully assembled in-wall toilet system ships and arrives ready for fast and easy installation. Installing a Geberit toilet system requires an adequate background in construction, plumbing and electrical work.

Inspect the package for damages that may have occurred during shipment. Check the unit's nameplate to verify whether the correct model shipped. Compare the invoice to the order form before receiving. Notify the freight carrier, then contact the manufacturer immediately to discuss existing discrepancies.
Read the instruction manual to follow proper installation protocol. Consult and conform to national and local building and fire codes. Flush all water supply lines before establishing connections.
Determine the toilet bowl's finished rim height. Measure the seat's height and finished, floor covering dimensions. Secure the 2-inch-by-6-inch framework to the floor covering and ceiling joists. Use mounting screws to reinforce support studs connected to the framework. Use a carpenter's level to assess rough edges.
Position the carrier to the rim height specifications. Drill an opening through the sole plate and floor covering to house the discharge fitting. Install the carrier assembly into the prepared opening. Align the carrier frame flush with the front of the support studs.
Use a permanent marker to create six-hole location reference points on the sole plate, which should total three holes on each support stud. Lift and remove the carrier assembly off of the support studs. Use a power driver to create the six 3/16-inch pilot holes into the sole plate and six 5/16-inch bolt holes for the support studs.
Install tank and carrier unit into the framework and fasten with stainless steel bolts.
Position the discharge fitting and 3-inch DWV drain pipe vertically, then establish a connection with coupling and stainless steel hose clamps. Do not cut the discharge fitting.
Set the water supply pressure at a range of 25 to 90 Psi. Use 1/2-inch-by-6-inch copper pipelines to extend an ear elbow supply side down and secure the elbow to the cross brace. Install the elbow and cross section connection to the tank's back reset section. Remove and set the tank door aside. Install a 1/2-inch NPT shut off valve through the tank's opening. Do not shut off the NTP valve. Do not connect the fit valve supply.
Mount the mud guard on to the tank access window. Snap in the tank access cover plate. Snap on the blue mud guard cover.
Mount two 1/2-inch-by-6-inch threaded rods on to the tank and carrier. Insert clean, protective plastic sleeves though the threaded rod fixtures. Push in protective pipe lugs into the flush pipe and discharge fitting's opening.
Remove the pipe plugs from the tank's discharge pipe openings located on the carrier assembly. Connect the toilet bowl inlet adapter to the discharge adapter. Install the bowl inlet adapter and discharge adapter into their corresponding openings. Install the gaskets on to the inlet adapter and discharge adapter.
Position a straight edge against the wall and align it flush across the fill pipe. Repeat the prior steps for the discharge adapter. Dislodge and carefully remove the inlet and discharge adapters from the tank and carrier assembly.
Assemble the inlet and discharge adapters with the gasket, placing it completely into the toilet bowl. Measure and mark the threaded nodule on the middle of the pipe. Lift and remove the pipes and gaskets from the toilet bowl. Subtract 1/8-inch from the toilet bowl to establish the proper specifications for sizing. Mark each pipe in accordance with its specification, measuring from the gasket side. Use a utility knife to cut off the excess lingering on the toilet's spigot side. Use a bevel to smooth out the leftover rough edges.
Slide off the plastic sheets from the threaded rods. Align the threaded rods to protrude three inches from the finished wall. Use an adjustable wrench and hex nuts to secured the threaded rods tot he carrier frame.
Lubricate the rubber seals with a rubber sealant. Avoid using plumbers' putty or silicone solvent. Attach adapters to the reserved wall side hub.
Position the toilet bowl on to the fixture rods. Thread the provided cap retainers, washers, nuts and hand-tighten only. Use a carpenter's level to assess the evenness of the toilet bowl. Use an adjustable wrench to tighten nuts. Do not over-torque the nuts. Install caps over the cap retainers. Use a caulking gun to seal off openings from excess moisture.
Dislodge and remove the mud guard cover. Use sheers to trim off excess material.
Throw away the mud guard cover and excess material. Pull out the cover plate.
Flush the water supply line and connect the braided hose to the stop valve. Attach the refill tube on to the overflow tunnel. Fill tank with water. Flush tank, then observe while mechanism refill it. Be sure the water level reaches 3/4 inches below overfill level.
Mount two-threaded lock pins to the finished wall. Align the lock pins flush with the finished wall. Turn the lock pin clockwise to mount in place. Position the actuator frame on to the boxes face with the base spring facing outward. Use a Philips screwdriver and two lock pins to secure the frame.
Insert the access panel flush actuator push rod into the rocker bushing, making sure to connect the taps to the actuator frame. Mount the push rod and lock it into placing by turning the push rod in a clockwise fashion.
Attach the actuator plate on to the frame's upper edge. Mount the actuator plate to the frame and test for functionality. Unwrap the protective foil from the frame.
